New Mother Clutcher HD primary clutch and puller tool made for 2016-2023 Can-Am Defender HD10 and the 2021-2023 Defender HD9 models.This clutch was made using the stronger Maverick X3 parts but then modified to make it bolt up and work on a Defender HD10! What you have now is a ready-to-bolt and use primary clutch rated for more than double the HP of the original Defender HD9 & HD10 clutch! Some upgraded parts include that it has the reinforced towers with the steel-plated slides to prevent button wear on the aluminum housing. It also has the stronger X3 style top cover (aka Governor cup assembly). The great news is, even though it's a lot tougher than the original HD8 clutch, we have it pre-tuned for the Defender HD10 ( and 2021-2023 HD9).This upgrade also lets the engine rev up a little higher to areas that unlock more of your mid range - full throttle torque and power. The mid throttle rpm's are approximately 400 rpms higher while full throttle, this clutch is tuned 600-800 rpms higher than stock until you exceed 55 mph. Once you exceed 55 mph, the top end is the same as the OEM primary which was 7200-7500 rpms.It comes ready to bolt on and use on your Defender!
