Smooth Shift Secondary PTFE Teflon Washers (3-Pack) // SKU: 05-TW-201-3
⚙️ APPLICATION ADVISORY: This 3-pack is configured specifically for secondary clutch setups requiring stacked shimming or dual-interface placement. Designed for Ski-Doo REV Gen4/Gen5 QRS secondary clutches, custom multi-washer spring stacks, and high-performance powersports driven clutches.
SKU: 05-TW-201-3
Package Contents: (3) 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 custom-tuned 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.
- Multi-Washer Shimming Capability: The 3-pack allows flexible setup configurations—sandwich both ends of the spring and retain an extra washer for spring preload shimming or as a spare.
- 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.
- Essential Kit Component: This is the exact secondary washer package included in our Ski-Doo 850 E-TEC Stage 2 Clutch Kits.
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. Sandwich the secondary spring with one washer at the base and one under the retainer, using the third washer to fine-tune spring preload or replace worn hardware.
- High-Horsepower Tuning: Stacking additional PTFE washers slightly increases spring preload height, increasing belt squeeze for aggressive setups without introducing metal-on-metal spring friction.
