Polaris 2021+ XP Turbo/S & Pro XP & Turbo R Shift-Tek Ultimate Clutch

Remove the primary and secondary outer cover. Remove the drive belt. (Figure 1)

Either pull primary clutch off the vehicle or keep it on the vehicle. In these instructions we kept the primary on the car. Loosen all (6) M6 primary clutch cover bolts with a 10mm socket. Only take (3) all the way out.

Remove the OEM spring. Next you will need a small Allen wrench and a 10mm socket to loosen the pins holding the OEM weights in. Perform this task one at a time.

Tighten the pin holding the weights till it stops. DO NOT over tighten the pins. The weights should move freely with ease.

Place the EVP spring onto the primary clutch. Place the primary clutch cover onto the spring and compress. Torque the M6 bolts down to 100in-lbs (8.3 ft-lbs).

With a 10mm socket and impact, remove the secondary bolt and washers. Remove secondary clutch.

Remove the movable sheave with the rollers, place it to the side. Place the stationary sheave and into a clutch compress tool. With a 15mm socket, remove the (3) bolts from the helix. Decompress the tool.

Remove the sheave, spring cup, and OEM spring. Place the Turquoise secondary spring into the EVP helix, followed by spring cup and sheave. Compress everything together. Use Blue Loctite on (3) M10 bolts, torque down.

Place both sheaves together, make sure all the rollers are moving properly. Reinstall the secondary onto the machine.

Reinstall the drive belt and remove the belt changing tool. Spin the secondary until the drive belt has seated.

Reinstall the CVT belt cover.
