Upgrading your side-by-side is about solving one real problem: matching the machine to the terrain you actually ride. Whether that means bolting on tires that claw through mud, a belt that survives high-torque climbs, or a sound bar you can hear over the engine, the right aftermarket part changes the entire feel of the ride.
I’m Mo Maruf — the founder and writer behind GoCarLife. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Below you’ll find a focused breakdown of the best utv aftermarket parts across tires, drivetrain components, and audio, ranked by real-world owner feedback and fitment data.
Our Picks at a Glance
How To Choose The Best UTV Aftermarket Parts
Focus your upgrade budget on the components that limit your machine’s performance on your primary terrain. Start with your most common terrain, then pick components that match the weight and power of your specific model.
Match the Part to the Terrain
A tire that excels in mud may slide on rocks, and a sport tire built for hard-packed trails won’t float in sand. Match the tread pattern to your dominant terrain—mud, rock, or hard-pack—for optimal grip.
Check Fitment Before You Commit
Confirm your exact model year and trim to avoid fitment issues, as small differences matter. For tires, check the wheel diameter and overall height, and see if you need a lift kit to clear a taller tire before you buy.

In‑Depth Reviews
1. SunF A033 32x10R15 Tires (Set of 4)
Our pick — over 4.5★ from 8,500+ verified ratings; the strongest balance of quality and price.
The all-terrain workhorse that balances value, grip, and a far smoother ride than stock.
When the review pages point to quality and value as the two biggest reasons owners are happy, the SunF A033 delivers where it counts. Each tire is rated to carry 992 pounds at 18 psi (the maximum pressure), so you have a clear picture of how much load it can shoulder. The 8-ply construction is designed to resist punctures, cuts, and impacts — exactly the kind of abuse trail tires take.
Buyers report the shoulder traction helps during turns and tricky maneuvers, and the general consensus is that the ride feels smoother than the factory rubber. The set is available in sizes from 22 to 32 inches, so it fits a broad range of ATVs, UTVs, and SxS machines. One detail to note: rims are not included, so you need to mount these on your existing wheels.
Compared to the more racing-oriented SunF A043, the A033 gives up a little track-day sharpness but gains everyday versatility. It’s a genuinely strong pick for riders who want one set of tires that can handle mud, sand, and rock without complaint.
What Owners Celebrate
- Outstanding traction in mud and snow conditions
- Appearance reminiscent of premium Maxxis Big Horn tires
- Smoother ride compared to stock tires
- Strong value at 32 inches with 8-ply toughness
What to Consider
- Rims not included — mount on your existing wheels
- Heavy 144-pound set, so expect a tougher install
Reach for these if: you want a do-everything tire that climbs over mud and snow while riding smoother than stock.
Look elsewhere if: you are chasing a dedicated racing tire for track days, where the sportier compound wins.
2. Ehaho 25″ 6-Speaker UTV Sound Bar
A 500-watt, IP66-protected sound bar that keeps the music loud and clear over the engine.
The defining spec here is a built-in Class-D amplifier pushing up to 500W of peak power through 2 tweeters, 2 mid-woofers, and 2 low-frequency radiators. What that means on the trail: crisp highs and punchy bass that stay audible even when you’re wearing a helmet or speeding down the trail. The IP66 waterproof rating means mud, rain, and sand won’t kill the party.
Beyond sheer volume, the RGB lighting wraps around the speaker units on both sides and pulses to the beat of your music. It is a detail owners enjoy, with the lights syncing to the music. Bluetooth 5.0 gives you a stable wireless connection, and you also get a 3.5 mm AUX and USB input for flash drives.
Mounting is universal for 1″–2″ roll cages, including Polaris RZR, Can-Am Defender, and golf carts. The detachable side-mounted cables keep the install clean, and two power cords (91″ and 130″) let you choose the best route to the battery. The only note from owners is that the bass won’t shake your chest, but at this price the sound quality is called “10/10”.
Our verdict: A rugged, loud, and genuinely waterproof sound bar that turns any ride into a party while staying affordable.
3. SuperATV Extreme CVT Drive Belt
An aramid-fiber belt built to handle extreme torque without the fraying and slippage.
This is not a universal belt — it is specifically designed for 2014+ Polaris RZR XP 1000 models (it will not fit the Trails and Rocks Edition). The core material is aramid fiber cord, which is what gives it reduced fraying and better power transfer during high-intensity rides. SuperATV also uses XC Technology and a knife-cut aramid cord to cope with extreme torque.
Owners who struggled with clutch problems report this as the best belt they have used, with improved clutch engagement on installation. The fit is exact — one owner called it a “perfect swap” — and the 16-ounce weight makes it easy to handle. The catch is durability: a few owners mention the belt breaking in under 30 miles, which is a statistically small group but worth knowing before you ride remote trails.
Treat this belt as a performance upgrade that requires periodic inspection, not a fit-and-forget part.
Strong upgrade: The improved clutch engagement is a noticeable, real benefit for RZR XP 1000 owners who have worn out stock belts.
4. SuperATV Rhino 2.0 Front Axle
A chromoly steel axle that replaces the OEM unit and comes with an 18-month warranty.
Designed to fit 2014-2023 Polaris RZR XP 1000, RZR XP 4 1000, and the 2015-16 High Lifter Edition, this front axle is built with chromoly steel and heat-treated for added strength. It replaces several OEM part numbers (including 1333123, 1333283, and 1333420), so you are getting an upgraded alternative to the factory unit. Note that it is not compatible with ABS.
The 18-month warranty gives you confidence that SuperATV stands behind the part, and owners upgrading from the original rhino shafts report it feels sturdy and holds up well. One owner replaced a torn boot and found the axle as expected — a solid, durable component. The 15-pound weight and 32-inch length are standard for this category.
For anyone rebuilding the front end of a late-model RZR XP 1000, this is a straightforward, high-quality replacement.
As an upgrade: The strongest case for this axle is the 18-month warranty plus the heat-treated chromoly construction that out-specs OEM.
5. NOAM NUTV4 Quad 4-Channel Sound System
A complete 4-speaker kit with amplifier and Bluetooth that mounts to any round roll bar.
Unlike a single sound bar, the NUTV4 Quad gives you four separate 4″ 2-way wake-tower speakers driven by a dedicated 4-channel amplifier. The system is all-in-one: amp, Bluetooth remote, speakers, and all the wiring are included. The speakers mount to any round roll bar from 1.5″–2″, and the mounting pads come in the box.
Owners highlight the sound quality and easy installation as the standout features, with Bluetooth connecting quickly — often within 5 seconds. The IPX6 waterproof rating means the speakers, amp, and remote survive rain and splashes. The system works on UTVs, ATVs, golf carts, and even boats, making it a versatile fleet audio solution.
The trade-off is bass — audiophiles will want a subwoofer for deep lows, but at this price the clarity and volume are excellent. Some owners did need to modify brackets for square trusses, so check your roll bar shape before ordering.
Why Buyers Love It
- Genuinely loud and clear even at full blast
- Complete kit — nothing else to buy
- BLuetooth pairs fast with auto-reconnect
- Water-resistant speakers, amp, and remote
Install Notes
- Bass is light — subwoofer needed for deep lows
- Square roll bars need custom brackets
Pick this for: a flexible, multi-vehicle audio kit with true tower speakers instead of a single bar.
skip it if: you prioritize deep bass over clear, loud mids and highs.
6. SunF A043 XC Racing Tires (Set of 4)
A cross-country racing tire that also stays quiet and smooth on paved roads.
For riders who split time between the track and the trail, the SunF A043 is a compelling middle ground. It comes in a staggered set — 27x9R12 in front and 27x11R12 in the rear — with a 6-ply construction for puncture resistance. The shoulder traction technology gives you superior grip in high-speed turns, which is exactly what cross-country racing demands.
Owner feedback is impressive on longevity: one rider logged over 1700 miles over 5.5 years on a Yamaha SxS and the tread still shows minimal wear with no cracks or splits. That same owner reports the tires handle mud, rocks, and light snow while staying smooth on pavement with no sway. The 14 psi maximum pressure keeps the ride comfortable.
Compared to the heavier 32-inch A033, the A043 is lighter and sharper, making it the better choice if you prioritize agility and speed over maximum floatation. It fits a 2013 Polaris RZR 570 with 14″ rims, but check your specific bolt pattern before ordering.
Our take: The best of both worlds — a racing-oriented tire that doesn’t punish you on the pavement drive home.
7. FORERUNNER 30x10R14 AURORA Tires (Pack of 4)
A budget-friendly 8-ply radial with a 17mm tread depth that surprises on snow and mud.
At 30 inches tall with a 14-inch rim diameter, the FORERUNNER AURORA is a solid entry point for riders who want big-tire capability without the top-tier price tag. Each tire carries a 970-pound load rating at 18 psi (the max pressure), and the 8-ply construction gives you serious resistance to punctures.
The tread depth is a standout 17mm — deep lugs that provide real bite. Customers note the tires work effectively even in 12 inches of snow, which is remarkable for a budget tire. The ride stays smooth up to 25 mph, and the aggressive pattern holds grip on trails and in mud.
The aggressive tread is slightly louder on pavement, and some tires may arrive deformed but straighten after a day in the sun. The grip-per-dollar value is exceptional for a budget tire.
Budget star: Deep 17mm lugs and an 8-ply carcass make this the value pick for trail riders who want serious traction.
8. Tusk Megabite 32×10-15 Tires (Set of 4)
The aggressively treaded 8-ply that owners say has serious “bite” and runs quiet on blacktop.
The Tusk Megabite is a tire designed for soft-to-medium terrain, and its 8-ply radial construction makes it tough enough for heavy abuse. The set carries a combined 4408-pound load capacity — that’s over 1,100 pounds per corner, which is plenty for a loaded utility side-by-side. The aggressive tread styling is not just for looks; it delivers real traction in mud and dirt.
Owners upgrading from the older Tusk Terrabite notice a clear improvement in mud performance with the Megabite’s more aggressive lugs. The ride is described as smooth, with one owner noting they are “quiet on the blacktop” — a welcome trait for a tire this aggressive. Another owner praises the perfect fit and easy installation.
Tusk tires run small—a 32″ may measure closer to 31″ at riding pressure. This matters most if you need maximum ground clearance.
In short: A high-load-capacity mud tire that doesn’t punish you with road noise — just double-check the sizing.
9. Tusk Terrabite 34×10-15 Tires (Set of 4)
A 34-inch, 8-ply radial with ¾-inch lugs built to crush medium-hard terrain.
The biggest tire on this list, the Tusk Terrabite is built for medium-hard terrain like dirt, gravel, rocky trails, and mixed surfaces. The ¾-inch deep aggressive tread pattern is the headline spec — that’s a seriously deep lug that digs in and holds. The 8-ply radial construction, combined with the heavy-duty sidewall tread armor, protects against punctures and cuts.
At 34 inches tall and 10 inches wide on a 15-inch rim, this is a commanding tire. The set carries a 4600-pound load capacity total. Reviewers point out excellent traction on hard-packed dirt and trails, with a smooth ride and notably low noise on pavement — one owner said these are “much quieter on pavement” than OEM tires.
It is not ideal for deep sand unless you keep your momentum up, and sizing can run small (some report a 32″ measuring closer to 30″). For riders who tackle hard, rocky terrain and want maximum clearance, this is a top-tier choice.
Standout Strengths
- ¾-inch deep lugs for serious traction on hard terrain
- Reinforced sidewalls resist punctures
- Quiet on pavement despite aggressive tread
- Huge 4600 lb total load capacity
Worth Knowing
- Runs small — check actual mounted height
- Not ideal for deep sand without momentum
Get this for: hard-packed trails and rocky climbs where ¾-inch of tread depth makes the difference.
Choose differently if: most of your riding is in deep sand or mud pits, where a paddle-style tire excels.
Understanding the Specs
Tire Size and Ply Rating
A tire size like 32x10R15 tells you the height (32 inches), width (10 inches), and rim diameter (15 inches, where the “R” means radial construction). The ply rating is the key durability number — an 8-ply tire resists punctures and cuts far better than a 6-ply, making it the right choice for rocky or abrasive terrain.
Load Capacity and Max Pressure
Load capacity tells you how much weight each tire (or set) can safely carry, so match it to your machine’s loaded weight. Maximum PSI is the highest pressure the tire is rated for — running at a lower pressure gives you a softer, more comfortable ride and more traction, but you lose some carrying capacity.
CVT Belt Material
The material of a CVT (continuously variable transmission) belt determines how well it handles heat and torque. Aramid fiber construction is the upgrade you want for high-horsepower machines — it resists fraying and slippage better than standard rubber belts, especially during hard acceleration or hill climbs.
IP Waterproof Ratings
For electronics like sound bars, the IP (Ingress Protection) rating tells you how well it resists dust and water. The first digit is dust protection and the second is water — an IP66 rating means fully dust-tight and protected against powerful water jets, which is ideal for mud-splattered trail riding.

Final Thoughts: The Verdict
For most riders, the best utv aftermarket parts investment is the SunF A033 Tire Set, because it delivers proven all-terrain traction at a price that leaves room for other upgrades. If your priority is staying in the saddle on long, hard-packed trail days, the Tusk Terrabite 34″ set is the premium choice with its ¾-inch lugs. For the rider who just wants the music loud and clear over the engine, the Ehaho sound bar is the crowd-pleaser that won’t let the weather stop the party.
