AA 2021 RZR Turbo, 2021-Up Pro XP/Turbo R/Pro S, & 2021+ Ranger XP 1000 STD/Crew Custom Cut Helix

The Aftermarket Assassins Custom Cut Helix adds acceleration and performance on the 2021 RZR Turbo, Pro XP, Turbo R, Pro S and 2021 and newer Ranger XP 1000. Add it to an AA S2 Clutch Kit to make it an S3 kit.

Why it holds up

• Tighter roller and EBS pocket for less clutch slop (clunk) and less chance of breaking rollers
• Two angles built for different loads and riding styles
• Adds acceleration and performance

Fits

• 2021 Polaris RZR Turbo and Turbo S
• 2021 and newer Polaris RZR Pro XP, Turbo R and Pro S
• 2021 and newer Polaris Ranger XP 1000 STD and Crew, including 2026 and newer XP 1000 Cab models
• Does not fit 2020 Pro XP or 2018 to 2020 Ranger models with the steel P90X helix

Good to know

• Performance Angle 1065: aggressive helix for acceleration, higher horsepower and fast pace drivers. Pro XP 2 seat with 30 to 33 inch dirt tires or 30 to 32 inch dune paddles. Pro XP 4 seat with 30 to 32 inch dirt tires or 28 to 30 inch paddles. Best on RZR Turbo or Turbo S with 29 to 32 inch tires or 28 to 30 inch paddles and a level 2 tune or higher. Best on Rangers with 27 to 30 inch tires and OEM gearing, or 31 to 35 inch tires with gear reduction.
• High Load Angle 1062: slightly less aggressive than the 1065 with good acceleration gains over OEM. Built for heavier vehicles, heavier tires, heavy sand or crawling. Pro XP 2 seat with 30 to 35 inch dirt tires or 30 to 32 inch paddles. Pro XP 4 seat with 30 to 33 inch dirt tires or 28 to 32 inch paddles. Best on RZR Turbo or Turbo S with 29 to 35 inch tires or 28 to 32 inch paddles, OEM tune or more power. Best on Rangers with 31 to 35 inch tires and OEM gearing. A great all around helix.
• Keep EBS: like factory. Most slower pace riders in mud, crawling or very hilly terrain keep it. Gets rid of the chatter noise, with a decel whine.
• Remove EBS: removes the EBS pocket in the helix. Gets rid of the roller clunk noise, with a decel whine. Most faster pace trail riders, racers and dune riders choose this.
• Clutch weights must be adjusted to run this helix. See the S3 setup on the setup sheet.
• Aftermarket Assassins highly recommends upgrading to its Heavy Duty P90X Secondary Clutch Rollers.
