Replaces Square Block Slider Secondary Clutch with Round Roller Tied Driven Clutch for Polaris UTV These clutch kits include the Team Tied driven clutch to replace the square slide block secondary that is stock on most 2016-22 naturally aspirated RZR models. They also include all of the clutch kit components (weights, springs and helix specific to your model and this conversion). Heavy Duty Outer Rollers (part# 50-371) and High Strength Spider Insert (part# 50-338) can be added to these kits for an even more robust combination.
