2022-Up Can Am Defender HD9 S1 Clutch Kit

The Aftermarket Assassins S1 Clutch Kit is a secondary clutch helix and spring upgrade for the Can-Am Defender HD9. It brings back peak RPM and acceleration lost to larger tires or added weight.

Why it holds up

• Secondary only. The primary clutch is left alone, which makes installation and adjustment easier.
• AA adjustable helix and stiffer secondary spring ramp RPM up faster, with settings for larger tires, paddles, tunes and exhaust
• Works with 27 to 33 inch tires and 28 to 32 inch paddles, and also with 34 to 35 inch tires
• Cooler belt temps, longer belt and clutch life and more consistent clutch performance

Fits

• 2022 and newer Can-Am Defender HD9, all models
• Machines with gear reduction in the transmission, portals or an aftermarket turbo kit need a fit check.
• Contact us before you order so we can confirm fit.

In the box

• AA 1053 adjustable helix
• Black secondary spring
• Helix adjustment tool
• Compression tool

Good to know

• A stock HD9 turns only 5500 to 6000 RPM peak. AA targets at or just over 6000 RPM on the OEM tune, and 6400 to 6700 RPM with AA tuning.
• The adjustable helix allows easy RPM changes, and a setup guideline is included.
• The AA install video is shown on an X3, which shares the same secondary clutch and process.
• Part number 101-1025.
