Smooth Shift Secondary PTFE Teflon Washers (2-Pack) // SKU: 05-TW-201-2
⚙️ APPLICATION ADVISORY: These self-lubricating PTFE washers install directly inside the secondary clutch spring cup (underneath and/or on top of the spring). Designed for Ski-Doo REV Gen4/Gen5 QRS clutches, Polaris RZR Pro R driven clutches, and high-performance aftermarket secondary clutches.
SKU: 05-TW-201-2
Package Contents: (2) Precision-Stamped Virgin PTFE (Teflon) Clutch Spring Washers
Primary Applications: Ski-Doo REV Gen4 & Gen5 850 E-TEC / 900 ACE Turbo QRS secondary clutches, and Polaris RZR Pro R driven clutches.
Eliminate torsional spring bind, lower operating temperatures, and unlock fluid, repeatable upshifting with Bikeman Performance Smooth Shift Secondary PTFE Teflon Washers. Under rapid acceleration and continuous cycling, driven clutch springs naturally twist as they compress. When the spring ends catch or bind against bare aluminum or steel spring retainers, the clutch hesitates to shift, leading to inconsistent backshifting, sluggish throttle recovery, and excess belt heat.
Manufactured from ultra-slick, industrial-grade virgin PTFE (Polytetrafluoroethylene), these low-friction washers act as an ultra-durable thrust bearing surface. By allowing the secondary spring to rotate freely throughout its entire compression stroke, they ensure silky-smooth progressive shifting and consistent side-pressure across the drive belt. Eliminating this mechanical drag stabilizes your shift curve and typically yields an immediate 25–50 peak RPM gain under full load.
Key Performance Features
- Eliminates Secondary Spring Bind: Lowers torsional friction between the spring ends and the clutch cup, allowing unobstructed spring compression and rotation.
- Consistent Shift Curves & Backshifting: Provides razor-sharp, predictable backshift response when entering and exiting corners or maneuvering deep powder.
- Reduces Sheave & Belt Temperatures: Smooth, uninhibited secondary action eliminates erratic belt scrub and heat-soak.
- Stabilizes Peak Operating RPM: Frees up parasitic friction in the drivetrain, frequently restoring or elevating peak shift speed by 25–50 RPM.
- Industrial Virgin PTFE: Resists extreme under-hood operating temperatures, belt dust abrasion, and heavy shock-loads without cracking, flattening, or galling.
Platform-Specific Application Notes
- Ski-Doo Snowmobiles (Gen4 & Gen5 QRS Clutches): Drop-in installation for 850 E-TEC, 850 Turbo, 600R, and 900 ACE Turbo QRS secondary clutches. Position one washer at the bottom of the spring cup and one on top to sandwich the secondary spring for optimal torsional release.
- Polaris RZR Pro R: For high-horsepower turbo and supercharger packages, stack two packs (four washers total) to simultaneously eliminate spring bind and add slight preload to the secondary spring, significantly increasing belt clamping force under high boost loads.
