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 S 4 Side-by-Side (2025-2026)
The Polaris RZR Pro R 4, spanning the 2025 and 2026 model years, is a high-performance side-by-side vehicle powered by a 1997cc (2.0L) ProStar Fury engine consistently producing 225 horsepower. This naturally aspirated engine remains unchanged across these two model years. For 2025, the RZR Pro R 4 was available in Sport and Ultimate trims. This year introduced new styling and an enhanced interior, including solid doors with a double latch, new dual hood scoops, upgraded contoured seating, and a new dual retractor harness. The Ultimate trim specifically gained 15-inch wheels with color-matched beadlock rims and heated and ventilated seats. In 2026, the Sport trim was discontinued for the Pro R 4 line. Available trims include the Ultimate and the new Ultra Edition. The Ultra Edition is a limited-production model (500 units globally) featuring the DYNAMIX DVS Suspension system with factory-integrated electronically controlled hydraulic locking sway bar links. The 2026 Ultimate trim received a new vertically oriented 10.4-inch infotainment touchscreen and new Pro Armor Trekker tires. FAQ:
