Defcom 7 Clutch Kit

Yes. If you're ordering multiple products (Float Mod + clutch kit + belt + tools, for example), add everything to your cart before checking out. Shipping is calculated based on the total order.

Most KWI products are DIY-friendly. Send-in services (Float Mod, sheave resurfacing) require shipping your clutches to us, but the reinstall is easy — we include a QR Code that will lead you to written instructions and/or YouTube install video with every order. Clutch kits, helixes, and springs typically install in 30–60 minutes with basic tools. The most common tool needed is a primary clutch puller for removing your primary clutch.

Our return and exchange policy can be found here.

Yes. All KWI Float Mods, clutch kits, and complete clutch systems work with tuned, supercharged and turbo boosted builds. Our clutch kits are specifically calibrated for your horsepower level, so when you order, tell us your tune and modifications so we can build for your exact setup.

Yes. KWI Clutching offers Affirm financing and Shop Pay on qualifying orders, giving you the option to pay over time in monthly installments. Financing terms are shown on each product page and at checkout.

No. not at this time. That is something we are looking into. 

Yes. Every KWI product comes with written installation instructions. For most Float Mod and clutch kit installs, we also have YouTube video walkthroughs that show the process step-by-step. Links to videos are provided with your order and on the KWI installs page.

Both. KWI sells complete send-in services (Float Mod, sheave resurfacing) AND individual parts (clutch kits, springs, weights, helixes, rollers, belts, tools). If you're a DIY installer or shop, we have everything you need. If you'd rather have us do the work, our send-in services handle it start to finish.

Yes, KWI ships worldwide. International shipping rates and customs duties are calculated at checkout. For send-in services, international customers are responsible for shipping their clutches to our Godley, Illinois facility. Contact us before ordering if you have questions about international send-ins.

No. KWI Float Mods, clutch kits, and other modifications do not void your OEM warranty. The Magnuson-Moss Warranty Act protects consumers from having their warranty voided by aftermarket parts unless the manufacturer can prove the aftermarket part caused a specific failure. If you have concerns, contact us before ordering and we can walk through specifics.

Our parts are compatible with components from other manufacturers, but we can't guarantee performance when mixing brands. For the best results, we recommend sticking with one company's components throughout your clutch system.

Every KWI product page includes a "Verify Fitment" tool that shows exactly which machines the product works with. If you're still not sure, our team can help — reach out through the website chat, email, or phone and tell us your machine's year, make, model, and any modifications (tune, turbo, tire size). We'll point you to the right product.

The process is: Order online → Complete our Clutch Ship-In booking form wh ice will be emailed to you (Check Spam if you don't see it)→ Pack and ship your clutches to us → We inspect and build your clutches → We ship them back → You install →Verify RPM and ride. Most send-in orders complete 7-10 business days in house.

In-house turnaround is 7–10 business days for most send-in services (Float Mod, sheave resurfacing, etc.). Add shipping time both ways on top of that.

Wheel horsepower gains vary by machine and starting condition, but 5–15 wheel horsepower on stock machines is typical. The gains come from three sources: (1) improved belt-to-sheave contact from resurfacing and floating, (2) better power delivery from properly calibrated clutch kits, and (3) reduced friction losses in the CVT system. Tuned and modified machines see larger gains because the clutches are properly matched to the tune.

For Can-Am machines: inspect after every hard ride, and remove/clean/lubricate the secondary shaft splines with moly grease every 500 miles. Primary rollers should be inspected for side-to-side play and replaced if wear is visible. Regular clutch maintenance is one of the biggest factors in belt and clutch life.

The Float Mod modifies the secondary sheave, so returning to fully stock would require replacing the fixed inner sheave. For most owners this isn't a concern — once you experience the smoother engagement and better belt life, there's no reason to go back. Machines with the Float Mod actually tend to hold or increase resale value in the enthusiast market.

Hard shifting is almost always caused by clutch misalignment or worn internals. On Can-Am machines, the secondary clutch is locked in place from the factory, which causes it to fight the primary during shift-out. The KWI Float Mod fixes this by machining the secondary to "float" and self-align, eliminating the resistance that causes hard shifting.

Print out your order confirmation and include it in the box. Wrap each clutch separately in bubble wrap or thick paper — never use packing peanuts, as they can damage clutch components in transit. Pack in a strong, double-walled box.

Every clutch we receive gets a full inspection before any work is started. If we find anything that needs attention — damaged sheaves, bad bearings, etc. — we email you a detailed estimate for approval before performing any additional work. You always sign off on cost before we proceed.

CVT stands for Continuously Variable Transmission. Instead of fixed gears, a CVT uses two variable-diameter pulleys (called clutches) connected by a belt. The primary clutch is on the engine crankshaft; the secondary clutch is on the transmission input shaft. As the engine speeds up, weights inside the primary force it to close, which pushes the belt outward — like shifting to a higher gear. Meanwhile, the secondary opens up to feed belt tension. This constant, smooth ratio change is what makes CVT systems so responsive.

This is when your secondary clutch spins at idle — you can see the belt rotating and hear the belt hum — even when the machine is in neutral. It's caused by drag on the belt from a misaligned or over-engaged primary clutch. On PDrive machines, primary internals can swell under heat and stick engaged. The Float Mod, combined with our PDrive internal replacements, addresses this at the root.

Clutch alignment refers to the primary and secondary clutches being perfectly parallel and correctly offset from each other. When aligned, the belt runs centered on both clutches, which means efficient power transfer and even belt wear. When misaligned — which is common from the factory — the belt rides uneven, generates heat, wears the belt edges, and robs power. The Float Mod fixes this by letting the secondary self-align to the primary.

The DX3 Conversion is a hardware upgrade for Defender and Commander owners with the QRS clutch. Your machine came from the factory with a weaker primary outer half, spring support, and governor cup than the X3 version — meaning they can't handle our AO-RC clutch kit. The DX3 Conversion replaces those three parts with X3-grade versions, which unlocks the full KWI upgrade path for your machine.

The Groovix is KWI's patented cooling helix, machined from aircraft-grade aluminum billet. Its unique rib and fan design draws air into the center of the secondary clutch, cooling the underside of the belt and sheaves. The result is significantly lower belt temperatures and longer belt life. The Groovix is included in all "Pro" tier Float Mods and can be purchased separately as an upgrade.

The KWI Float Mod is our proprietary CVT clutch modification that solves multiple issues with the Can-Am clutch system — including hard shifting, belt failures, and performance loss. Specifically, it addresses factory belt misalignment, worn parts, and stuck primary clutches.

We machine all four sheaves and the secondary clutch to "float" on the shaft, allowing it to self-align with the primary during operation. We also replace the secondary rollers, and on PDrive clutches, we replace the primary rollers — which wear quickly — along with internal parts that swell under heat and cause the clutch to stick open.

The result: smoother shifting, lower belt temperatures, dramatically longer belt life, and better power transfer to the wheels.

KWI supports Can-Am (X3, Defender, Commander), Polaris (RZR XP, Pro R, Pro S, Turbo R, Turbo S, XP1000, Xpedition, Ranger), Kawasaki (Teryx, KRX, H2, Ridge), and Speed UTV. Fitment on each product page shows exactly which models are supported.

We accept all major credit cards, Apple Pay, Google Pay, Shop Pay (including installments), Affirm financing, and PayPal.

At minimum: a primary clutch puller (specific to your machine — we sell them), a torque wrench, sockets, a belt removal tool, and clean workspace. For more complex installs, additional tools may be needed. Each product page lists required tools for your specific vehicle (SPEED UTV, RZR, etc), for example our V2 Complete Tool Kit includes everything you need for most Can-Am installs.

The difference is which clutch system your machine came with from Can-Am. PDrive clutches are found on 2021+ Can-Am X3 turbo models Defender DH11. QRS clutches are on 2017–2021 X3s and on Select Defender/Commander/Maverick models. The Float Mod modification is similar in concept for both, but the specific parts, machining, and packages are tailored to each clutch system.

Belts burn for four main reasons: (1) clutch misalignment causing the belt to ride unevenly, (2) excessive heat from clutch friction, (3) worn or damaged sheave surfaces, and (4) poor calibration for your specific machine setup. The KWI Float Mod fixes reasons 1–3 by aligning and resurfacing the clutches, and our clutch kits fix #4 by calibrating your clutches for your exact machine.

No. Any transmission seal guard (also called a seal saver) is physically incompatible with the KWI Float Mod because the seal guard occupies the exact space the secondary clutch needs to "float." You will need to remove your seal guard before installing the Float Mod.
