Aftermarket Assassins - Polaris Ranger XP 1000 / Crew XP 1000 New Body Style S4 Clutch Kit with AA Heavy Duty Primary & Secondary

This clutch kit is designed for 2026+ XP 1000 Cab models and 2022+ NorthStar Editions. These models use a larger crankshaft taper. NorthStar Editions include 3 inner clutch cover bolts for additional clearance. This kit does NOT fit Ranger 61HP Single Cam Models.

Kit Includes:

• AA Primary Clutch with AA Revolver Billet Clutch Cover and Tower Lock
• Primary bolt
• AA magnetic adjustable clutch weights
• AA primary spring
• Weight setup sheet
• Custom primary spring limiter
• Replacement factory secondary clutch
• AA secondary spring
• AA custom cut helix
• AA Extreme Heavy Duty primary sliders and AA HD secondary rollers (pre-installed)

Primary Clutch Features:

• Heavy duty AA design with encapsulated tower, proven on 2016-2020 RZR Turbo models
• Higher grade tool steel post with AA HD sliders assembled to AA specifications
• Better power transfer and lower belt temperatures than OEM P90X or other aftermarket clutches
• Improved belt grip, especially at higher RPM
• Buttery smooth engagement with no factory jerk at idle
• Faster acceleration and wicked throttle response
• Quicker downshifts and cooler running belt temperatures
• Longer belt and clutch life with more consistent performance
• Easily adjustable as needed

Helix Options:

• Performance Helix 1065: Aggressive helix designed for acceleration and higher horsepower. Best for Rangers with 27-30" tires and OEM gearing, or 31-35" tires with gear reduction.
• High Load Helix 1062: Slightly less aggressive with good acceleration gains. Designed for heavier vehicles, heavier tires, heavy sand loads, or crawling. Best for Rangers with 31-35" tires and OEM gearing. Excellent all-around option.

Helix Features:

• Tighter roller and EBS pocket for less clutch slop and reduced chance of roller breakage

Engine Braking (EBS) Options:

• Keep EBS: Factory-style operation. Recommended for slower-pace riders (mud, crawling, hilly terrain). Eliminates chatter noise but produces decel whine.
• Remove EBS: Removes EBS pocket from helix. Eliminates roller clunk noise but produces decel whine. Recommended for faster-pace trail riders, racers, and dune riders.

Clutch Weights:

• Easily adjustable with simple magnets
• Custom AA profile with nitrocarburizing coating for increased wear resistance, improved fatigue strength, and added surface lubricity
• Allows tuning for different applications and modifications without purchasing additional parts
• Magnetic design optimizes weight placement for best performance

Assembly and Setup:

• Clutch does not come pre-assembled. Setup weights according to included setup chart, then install weights and spring.
• Optional assembly service available for +$25 (requires information about engine modifications and tire size/type)
• Comprehensive setup guidelines included for different tire sizes and variables

Important Notes:

• This clutch is louder at idle due to loose spider/slider tolerance until engine RPM increases
• May slightly contact plastic cover at idle, causing minor wear marks (uncommon but possible due to cover variances)
• Primary bolt has a shortened head to clear under cover; use care when tightening with an 18mm 6-point socket to avoid stripping
• P90X Specific Clutch Puller required for OEM clutch removal; AA clutch uses standard XPT/XP1000 primary clutch puller
• P90X Secondary Clutch Alignment Shim Kit available for alignment issues
• Stryker Belt recommended for improved grip in clutch

• 2021 All models: 116-1013
• 2022+ All models except NorthStar: 116-1013
