Complete Heavy Duty AA Primary Clutch Kit

This kit features the same encapsulated tower design found on 2016-2020 RZR Turbo models. The primary clutch holds power better, resists failure, and slips the belt less than OEM options. It maintains superior belt grip at higher RPM and is proven on high horsepower vehicles. The clutch is made with higher grade tool steel and assembled with AA HD sliders, paired with an AA Revolver Billet Clutch Cover with Tower Lock for added strength and airflow.

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
• AA secondary spring
• AA custom cut helix
• AA Extreme Heavy Duty primary sliders (pre-installed)

Performance Benefits:

• Better power transfer and acceleration compared to OEM P90X clutch
• Lower belt temperatures
• Buttery smooth engagement with no factory jerk at idle
• Wicked throttle response and quicker downshifts
• Faster acceleration
• Longer belt and clutch life
• More consistent clutch performance
• Easily adjustable for different applications
• Tighter roller and EBS pocket for less clutch slop and reduced roller breakage

Helix Options:

• Performance Helix 107-1065: 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 107-1062: 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.

EBS (Engine Braking) 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 magnetic weights with custom AA profile. Features the best coating on the market (nitrocarburizing) for increased wear resistance, improved fatigue strength, and added surface lubricity. Allows tuning for different applications and modifications without purchasing additional parts.

Assembly: Primary clutch does not come pre-assembled. Set up weights according to the included setup chart, then install weights and spring. Optional assembly service available for +$25 (requires engine modification and tire size/type information).

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)
• Primary bolt has a shortened head to clear under cover; use care when tightening with an 18mm 6-point socket
• 6 spring cover button head allen bolts are 4mm; use correct size to avoid stripping
• Requires P90X clutch puller to remove OEM clutch; uses standard XPT/XP1000 primary clutch puller for AA clutch
• Requires clutch compression tool #1 to install helix/spring in secondary clutch

Recommendations:

• Highly recommended with engine tuning to reach peak Ranger 1K motor power
• Essential when running larger tires
• Pair with AA Stryker Belt for improved grip
• Use P90X Secondary Clutch Alignment Shim Kit if alignment issues exist
• Consider upgrading to Heavy Duty P90X Secondary Clutch Rollers
• Optional: Butter Shift Washers for increased spring pressure and smoother shifts
