The AA Adjustable Helix Kit lets you dial in peak RPM on the Can-Am Maverick X3 and Defender faster than adjusting primary weights. It matters most for riders who switch tires often or ride both dunes and trails.

Why it holds up

  • Adjusts quickly at the helix, so peak RPM can be set for best performance
  • Excellent acceleration gains and better power transfer to the rear wheels
  • On the 172 HP X3 R it is more aggressive all around for harder up shifts, with strong RPM ramp up
  • Works with the stock secondary spring, which AA found worked best out of more than 50 tested

Fits

  • 2018 to 2022 Can-Am Maverick X3 120 HP
  • 2018 and newer Can-Am Maverick X3 172 HP, 195 HP and 200 HP base models
  • 2026 Can-Am Defender HD11
  • 2020 and newer Can-Am Defender HD10 and 2022 and newer Defender HD9. These must already have the AA black secondary spring.
  • Also fits 154 HP X3 models, but AA has no base setups for that model

In the box

  • AA adjustable helix
  • Helix adjustment tool
  • Compression tool

Good to know

  • Performance Helix 1053: aggressive, built for acceleration, higher horsepower and fast pace drivers.
  • High Load Helix 1050: slightly less aggressive than the 1053 with good gains over OEM. Built for heavier vehicles, heavier tires, heavy sand load or crawling.
  • 172 HP X3 R: installed in hole C1 it drops RPM about 200 to 300. The ideal setup adds the AA clutch kit with all 6 arms.
  • 195 to 200 HP X3 RR: works with a stock primary but needs fine tuning. AA suggests its S3 clutch kit, which adds primary weights and a spring.
  • Target peak RPM with stock or other tunes limited to 8300 to 8700 RPM is 7700 to 7900. With AA tunes or others limited to 8800 to 9000 RPM, target 7900 to 8300. Test on fairly level ground from a 10 to 20 MPH roll on to full throttle and read RPM passing 55 to 60 MPH.
  • Defender HD9 and HD10 peak RPM should be 6000 to 6300 at 40 to 50 MPH on stock tuning, or 6400 to 6700 with AA tuning.
  • The install video says a separate compression tool is needed. The compression tool is now included in the kit.
  • Part number 108-1040.
