Description
Dynojet's Secondary Clutch Spring Cup Kit for the Polaris P90x Clutch adds vital durability to your secondary clutch spring. Made of billet, this is an upgrade from stock and is designed to keep the secondary spring aligned in the helix.
Keep your Polaris machine running strong with this Secondary Clutch Spring Cup Kit. This part is an upgrade over the stock spring cup, which can render the vehicle inoperable if broken. We've forged this piece from durable billet, allowing it to withstand the high performance you expect from your UTV. Because of its cone shape, this spring cup makes sure the secondary spring is aligned better in the helix.
This fits all models with the P90x Clutch.

Vehicle Information
Polaris RZR Pro XP 4 Side-by-Side (2020-2026)
The Polaris RZR Pro XP 4, available from 2020 to 2026, stands as a high-performance side-by-side designed for thrilling off-road adventures. This powerful four-seater is consistently equipped with a 925cc, 4-stroke DOHC twin-cylinder turbocharged engine, delivering a robust 181 horsepower across all model years. Throughout its production, the RZR Pro XP 4 has been offered in distinct trim levels: the capable Sport base model, the feature-rich Premium trim with Polaris Ride Command, and the top-tier Ultimate, boasting advanced DYNAMIX 2.0 Active Suspension and premium audio. While the core engine and platform have remained consistent, Polaris has implemented incremental improvements rather than a full generation change. Notable updates include revisions to the intake system and cylinder head in early 2020 models, and a significant update to the transmission shaft and secondary clutch from 2021 onwards, making these components non-interchangeable with 2020 models. Further refinements in 2025 brought an updated interior across all Pro models, with improved seating and controls, including four-point harnesses for Ultimate trims. The 2026 models will standardize new inner door handles and continue to offer FOX shocks on Sport trims and DYNAMIX 2.0 on Ultimate trims. FAQ:
