ATV & UTV Transmission and Drivetrain Parts – Keep Power Moving to the Ground

The drivetrain is the mechanical chain from the engine to the wheels - and when any link in that chain fails, you're either pushing or calling for a truck. CV boots that tear open on a rock, sprockets worn to hooks, chains stretched past spec, or clutch components that slip under load are all preventable problems when you catch them early and replace with parts built for the punishment off-road machines take.

At RV Trader Accessories, we carry ATV and UTV transmission and drivetrain parts from All Balls, QuadBoss, JT Sprockets, Renthal, Vortex Racing, BikeMaster, Hinson, Hot Rods, Max-Torque, and Wiseco - covering CV boot repair kits, front and rear sprockets, chain and sprocket kits, clutch covers and gaskets, and clutch parts across thousands of fitments.

What's in This Collection

CV Boot Repair Kits

CV boot kits are the largest single product type in this collection, with over 2,600 SKUs from All Balls and QuadBoss covering front and rear, inner and outer boot positions across virtually every ATV and UTV make and model in the market.

What a CV boot does - and what happens when it fails. The constant velocity joint is what allows your axle halfshaft to transfer power at variable angles as the suspension compresses and extends. The boot is the rubber cover that keeps molybdenum disulfide grease packed around the joint and keeps dirt, water, and debris out. When the boot tears - which happens from rock strikes, trail debris, and simple age - grease escapes and contamination enters. The joint heats up, wear accelerates, and if you keep riding on a torn boot, the CV joint itself fails. At that point you're replacing the entire halfshaft instead of a $40-$80 boot kit.

The rule among experienced ATV and UTV mechanics is simple: inspect boots at every service, and stop riding immediately when one tears. Continuing to operate a machine with a torn CV boot is the fastest way to turn a cheap maintenance item into an expensive repair.

Inner vs. outer, front vs. rear. Each axle halfshaft has two joints - one at the wheel end (outer) and one at the differential end (inner) - each covered by its own boot. Front and rear axles are separate assemblies. A complete front kit covers both inner and outer boots on the front axle; a complete rear kit covers both positions on the rear. Some kits cover only a single position (inner only or outer only), which matters when only one boot is damaged and the other is still serviceable.

All Balls CV boot kits use DCR66 OEM-grade rubber compounded specifically for ATV and UTV axle demands - 40% higher tensile strength than conventional CV boot materials, 50% more abrasion resistant, and cold-tested to -40°F. Each kit includes stainless steel clamps designed to tighten without special tools and a lithium-based molybdenum grease for repacking the joint. Fitment coverage spans all major platforms including Can-Am (Outlander, Maverick, Commander, Renegade), Polaris (Sportsman, Ranger, RZR), Yamaha (Grizzly, YFM), Honda (Pioneer, TRX), Kawasaki (Brute Force), and Arctic Cat.

QuadBoss mirrors All Balls' coverage with their own complete front and rear CV boot kits for the same platforms, offering an alternative fitment option on popular models like the Yamaha YFM550 and YFM700 Grizzly.

Representative platform coverage in this collection includes:

• Can-Am Maverick 1000 XDS-DPS, Maverick MAX 1000, Outlander 800R STD 4x4, Outlander MAX 800R, Outlander MAX 800 LTD, Outlander 500 XT, Outlander 1000 EFI XMR, Commander 800, Renegade 800 XXC
• Polaris Ranger 4x4 800 EFI, Sportsman Forest 850 (2011-2015)
• Yamaha YFM400 Grizzly IRS, YFM550 Grizzly, YFM700 Grizzly

Sprockets and Drive Chains

The sprocket and chain category covers over 380 sprocket SKUs and a wide range of chain-and-sprocket combination kits across ATV, UTV, dirt bike, street, and adventure bike fitments, primarily from JT Sprockets, Renthal, and Vortex Racing.

JT Sprockets is the world's largest manufacturer of aftermarket sprockets, producing more units than all other aftermarket brands combined. Based in London, JT uses SCM420 chromoly steel for front sprockets, high carbon C49 steel for rear sprockets - a steel grade they're the only sprocket manufacturer to use - and aviation-grade 7075-T6 aluminium for lightweight competition sprockets. Each sprocket is manufactured by hobbing and CNC machining, then heat-treated and hand-finished. The result is a sprocket that outlasts mild steel or surface-hardened alternatives by up to two to three times.

The JT collection here covers front and rear steel sprocket kits for a wide range of ATV platforms: Honda TRX300EX Sportrax (2001-2008), Honda TRX200D FourTrax Type II (1991-1997), Kawasaki KLT250 C1/C2/C3 Prairie (1983-1985), Suzuki DR125 SE and DR-Z125L, and Yamaha YFM350R Raptor (2004-2013). JT's Z3 Super Heavy Duty X-Ring Chain in 520-120 link is also available as a standalone chain for riders building their own sprocket and chain combination.

BikeMaster covers chain-and-sprocket kit combinations including 520H heavy-duty and 520/525 BMOR/BMXR sealed chain kits matched to front and rear sprockets for popular ATV and street platforms - Yamaha YFM350R Raptor, YFM660R Raptor, BMW F650 GS Dakar, and KTM 690 Duke among others.

Renthal is a UK-based manufacturer with decades of motocross and off-road racing heritage. Their rear sprockets in this collection cover high-demand street and sport platforms including the Kawasaki Ninja ZX-6R 636. Renthal sprockets are manufactured from a proprietary high-tensile aluminum alloy engineered for resistance to wear under race-level stress.

Vortex Racing produces steel rear sprockets for sport and track-focused platforms. Their 454S-40 steel rear sprocket in 525 pitch covers the Kawasaki ZX10R, ZX6R, ZX7R, Z1000, and ZZR600 - machines where sprocket quality directly affects track reliability.

Clutch Components

Hinson clutch components represent the performance end of the clutch category. Founded in 1992 by Wayne Hinson, the brand built its reputation in ATV racing before expanding into motocross, supercross, and road racing. Hinson clutch baskets, pressure plates, and inner hubs have been involved in over 250 National and World Championship wins. The two Hinson SKUs in this collection cover riders doing clutch upgrades on platforms where the stock basket and hardware are inadequate for the demands of the riding style or engine modifications.

Hot Rods covers clutch cover gaskets for ATV platforms where the clutch cover needs to be resealed during clutch service. With 11 gasket SKUs, Hot Rods handles the sealing end of a clutch job that's otherwise complete with the basket and plate hardware already in hand.

Max-Torque produces sprocket clutch components for go-kart and small engine applications, including the SS1258 5/8" Sprocket Clutch for 35 chain in 12-tooth configuration - a utility-grade component for small-displacement or specialty machines outside the standard ATV/UTV fitment range.

Wiseco covers select drivetrain components including clutch-side hardware for ATV and UTV platforms where Wiseco's engine rebuild and performance component catalog extends into the drivetrain.

How to Know When Drivetrain Parts Need Replacing

CV boots: Inspect visually at every service - look for cracking, splitting, or tears in the rubber accordion folds, and check for grease thrown outward onto the surrounding suspension and brake components. Grease outside the boot means the seal is already compromised. Don't wait for noise; CV joints can deteriorate quickly once contaminated.

Sprockets: Worn sprockets develop a hooked or shark-fin tooth profile instead of the symmetric curved shape of a new sprocket. Hooked teeth accelerate chain wear and cause the chain to skip under load. Replace the chain and both sprockets together - installing a new chain on worn sprockets, or worn sprockets with a new chain, causes rapid wear of the new component.

Drive chain: A chain that has stretched beyond the adjustment range of the tensioner, has stiff links that don't flex smoothly, or shows visible rust, kinking, or damaged side plates needs replacement. Measure chain stretch with a ruler - most chains show a half-link of usable stretch before replacement is due. Check your machine's service manual for the spec.

Clutch: Slipping under hard acceleration, difficulty finding neutral, or a dragging clutch that doesn't fully disengage are the signs of worn clutch fiber plates, springs, or a damaged basket. A basket with notched engagement tangs - caused by the fiber plate ears digging into the aluminum - prevents smooth clutch action even with new plates installed.

How to Choose the Right CV Boot Kit

Match to your exact year, make, model, and submodel. CV axle geometry varies between model years and trim levels. Inner and outer boots have different dimensions even on the same axle, and front and rear boots differ from each other. The position (front/rear, inner/outer) must match the damaged boot.

Complete kits vs. single-position kits. A complete front kit covers both inner and outer boots on the front axle. A single-position kit covers only one joint. If you're doing a full axle service or both boots on one axle are suspect, the complete kit is the better value. If only one boot is damaged and the other is new, a single-position kit is appropriate.

Don't skip the grease repacking. Every quality boot kit includes grease for a reason. Once the joint is exposed during boot replacement, repacking with fresh molybdenum grease is not optional - it's what determines how long the new boot lasts.

How to Choose the Right Sprocket

Front and rear sprockets are sold separately or as kits. A chain-and-sprocket kit bundles both sprockets and the drive chain, which is the right approach when doing a full drivetrain refresh. Replacing only one sprocket while reusing an old chain and worn counterpart accelerates wear on the new part.

Tooth count determines gearing. More teeth on the rear sprocket (or fewer on the front) lowers gearing for more low-end torque and quicker acceleration - preferred for tight trail riding and technical terrain. Fewer rear teeth (or more front) raises top-end speed. Stock tooth count restores factory gearing. Many riders go one or two teeth up or down from stock depending on their primary terrain.

Steel vs. aluminum rear sprockets. Steel rear sprockets last significantly longer than aluminum in abrasive or muddy conditions. Aluminum sprockets are lighter and preferred for racing applications where weight matters more than longevity. For trail riding and utility use, JT's high-carbon C49 steel rear sprockets are the practical choice.

FAQ

How do I know if my CV boot is torn? Look for grease thrown onto the inside of the wheel, surrounding suspension components, or the brake rotor and caliper. A direct visual inspection of the boot accordion folds will show any tears, cracks, or splits. Also listen for clicking or popping sounds when turning under power, which indicates the CV joint has already been contaminated and may need replacement beyond just the boot.

Can I ride with a torn CV boot? No - or at least, not beyond what's needed to get the machine off the trail. Riding on a torn boot exposes the CV joint to dirt, water, and debris. Contamination causes rapid heat buildup and wear inside the joint. What starts as a $40-$80 boot kit repair can become a full halfshaft replacement within a short riding session.

What's the difference between inner and outer CV boot kits? The inner boot covers the joint at the differential end of the halfshaft; the outer boot covers the joint at the wheel end. They have different dimensions and bellows profiles. Front and rear inner/outer positions are also different from each other. You need to identify which position is damaged - front or rear, inner or outer - before ordering.

When should I replace my sprockets and chain together? Sprockets and chain should always be replaced as a set. Installing a new chain on worn sprockets causes the new chain to wear rapidly as it conforms to the hooked tooth profile. Installing new sprockets with an old stretched chain has the same effect. A chain-and-sprocket kit from JT Sprockets or BikeMaster handles all three components in one purchase.

What's the difference between steel and aluminum rear sprockets? Steel rear sprockets last significantly longer in abrasive and muddy conditions, making them the practical choice for trail and utility riding. Aluminum sprockets are lighter - a meaningful advantage in racing applications - but wear faster in harsh environments. JT's high-carbon C49 steel is the most durable material available in the aftermarket.

What does tooth count on a sprocket change? Adding teeth to the rear sprocket (or removing teeth from the front) lowers your overall gearing, increasing low-end torque and acceleration at the cost of top speed. Removing rear teeth (or adding front) has the opposite effect. Most trail riders stay within one or two teeth of the stock count; motocross and racing applications may call for larger adjustments depending on the track or terrain type.

What is a Hinson clutch basket and why would I upgrade? The stock clutch basket on many ATVs is cast aluminum, which develops notches where the fiber plate tangs engage over time. These notches prevent smooth clutch engagement and disengagement. A Hinson billet aluminum basket machines the engagement surfaces to a much tighter tolerance and holds that tolerance longer. It's the standard upgrade for machines that see aggressive or competitive riding.
