2020 POLARIS RZR PRO XP SHIFT-TEK PROGRESSIVE HELIX

The helix is the “brain” of the driven clutch and it will respond differently with a change in load to the machine, for example, bigger tires or increasing gross weight to the vehicle. With the 36-42 helix, you will gain more out of your driven clutch and have a quicker backshift compared to the OEM helix while raising your rpms and top speed.  Does not fit 2021 Pro XP
