UTV Secondary Clutch

UTV Secondary Clutch Upgrades for Side by Sides

The secondary clutch is one of the most important performance controls on any utility terrain vehicle. It works alongside the primary to regulate belt engagement, manage RPM, and transfer power to the wheels. On stock machines, the factory secondary clutch is built to handle a baseline load. Push that machine harder with larger tires, added passenger weight, mud runs, or a power upgrade, and it starts to fall short. That is where an aftermarket secondary clutch or rebuild kit makes a real difference in how your off-road vehicle handles and performs on the trail.

Fueled UTV carries secondary clutch parts and assemblies built for popular utility task vehicle platforms including Polaris RZR, Can-Am Maverick X3, Kawasaki KRX, and Polaris Ranger models. The selection includes full secondary assemblies, adjustable helix upgrades, replacement rollers, alignment shims, and rebuild kits. Brands like Aftermarket Assassins, KWI Clutching, Gilomen Innovations, EPI Performance, Dalton Industries, and SuperATV offer options designed to improve belt grip, lower operating temperatures, and dial in performance depending on tire size, terrain type, and riding style. Whether the job is replacing worn-out components or upgrading to a full billet floating secondary, you can find the right part here.

FAQ 

What does a secondary clutch do on a UTV?

The secondary clutch receives the drive belt from the primary clutch and controls how power gets delivered to the gearbox. It manages back-shifting, belt tension, and how quickly your utility terrain vehicle builds speed. When it is tuned correctly for your setup, throttle response and power transfer improve noticeably.

When should I upgrade my UTV secondary clutch?

An upgrade makes sense when you run larger tires, add significant passenger or cargo weight, install a power upgrade like a tune or turbo kit, or notice belt slipping, overheating, or inconsistent RPM on the trail. Models running in mud or demanding terrain tend to benefit most from an aftermarket secondary.

What brands of secondary clutch parts does Fueled UTV carry?

Fueled UTV stocks secondary clutch parts from Aftermarket Assassins, KWI Clutching, Gilomen Innovations, EPI Performance, Dalton Industries, SuperATV, and more. Fitment varies by make and model, so use the filter fields to find parts built for your specific side-by-side.

What is a helix upgrade for a secondary clutch?

The helix sits inside the secondary clutch and controls the angle at which the sheaves shift. A steeper or shallower angle changes how fast the secondary shifts and where peak RPM lands. Aftermarket helix kits, like those from Aftermarket Assassins, are adjustable so you can test and fine-tune the setup to match your tire size and riding style without buying extra parts.

Do secondary clutch parts fit all UTV models?

No. Fitment varies by make, model, year, and in some cases, crew cab configuration or machine width. Always confirm compatibility before you buy. Most product pages on Fueled UTV list supported models directly, and the support team can help you find the right fit if you are not sure.

Can I rebuild my secondary clutch instead of replacing it?

Yes. Roller kits, helix upgrades, alignment shims, and rebuild kits let you restore or improve a worn secondary without purchasing a full assembly. If the sheaves are in good shape, a targeted rebuild is a cost-effective way to get the clutch performing as it should.

How do I know if my secondary clutch is failing?

Common signs include faster-than-expected belt wear, inconsistent power delivery, a drop in top speed, and higher-than-normal belt temperatures. A visual inspection of the rollers, helix, and sheave faces will often reveal wear. Catching it early keeps belt and clutch costs lower over time.
