Aftermarket Assassins - Polaris RZR XP S4 Clutch Kit with AA Heavy Duty Primary & Secondary

Does NOT fit 2015-2023 RZR XP 1000 models.

From trail rigs to high horsepower setups, this is the only clutch we will run on our shop vehicles. This kit includes our complete heavy duty AA primary clutch with the same encapsulated tower design found on the 2016-2020 RZR Turbo and 2024+ RZR XP 1000 models. This clutch holds power better, resists exploding, and slips the belt less than alternatives. It meets the demands of high horsepower vehicles and holds belt grip better than billet clutches, especially at higher RPM.

Kit Includes:

• AA Primary Clutch with billet Revolver cover and Tower Lock
• AA magnetic adjustable clutch weights
• Weight setup sheet
• AA primary spring
• Custom Primary Limiter
• Inner cover bolts for clearance
• AA replacement secondary clutch
• AA Helix
• AA secondary spring
• AA Extreme Heavy Duty primary sliders
• AA HD secondary rollers (pre-installed)

The clutch does not come assembled. Set up your weights according to the included setup chart, then install the weights and spring. Assembly service available for an additional fee.

Performance Benefits:

• Wicked acceleration and instant clutch response
• More efficient power transfer to wheels: +6 RWHP mid-range, +1 RWHP at peak speeds
• Cooler running belt temperatures, especially with larger tires or paddles
• Longer belt and clutch life
• More consistent clutch performance
• Easily adjustable for different applications
• Very slightly higher engagement but extremely smooth
• Tighter roller and EBS pocket for less clutch slop and reduced roller breakage

Helix Options:

• High Load Helix 1067: Slightly less aggressive than performance helix. Designed for heavier vehicles, heavier tires, heavy sand loads, or crawling. Works on 2 and 4 seat models with 30-35" tires or 30-33" paddles.
• Performance Helix 1068: Aggressive helix for acceleration and higher horsepower. Best with tuned vehicles. Works on 2 seat models with 30-32" tires. Not suggested for 4 seat models.

Engine Braking (EBS) Options:

• Keep EBS: Like factory. Recommended for slower pace riders (mud, crawling, hilly terrain). Eliminates chatter noise but has decel whine.
• Remove EBS: Removes EBS pocket in helix. Eliminates roller clunk noise but has decel whine. Recommended for faster pace trail riders, racers, or dune riders.

Setup Options:

The included setup sheet provides guidelines for dunes, mud, or all-around trail riding. A "Cruiser" setup is available for those seeking less cruising RPM and reduced noise. This setup drops peak RPM to roughly 7500-7800 RPM instead of factory 8300-8600 RPM, offering smoother engagement and excellent crawling ability. You can easily switch between setups in 15-30 minutes.

Clutch Weights:

Recoil clutch weights are easily adjustable with simple magnets. They feature a custom AA profile and the best coating on the market (nitrocarburizing) for increased wear resistance, improved fatigue strength, and added surface lubricity. Magnetic weights allow tuning for many different applications and modifications without purchasing extra parts.

Compatibility:

• Works with tire sizes 30" to 35" and paddles 28" to 33"
• Works great with both stock or modified machines
• Recommended with tuning for higher RPM to reach peak power of 2024+ RZR XP 1000
• A must-have when running larger tires or paddles
