Flywheel Washer for Briggs Raptor Engines - Superseded to 690582

Overlooked but indispensable, the flywheel washer (SKU: 555083) safeguards your Briggs Raptor engine's balance. Now superseded to 690582, it sits between the flywheel and nut to absorb shocks and maintain alignment during high-RPM spins.

Without it, uneven wear leads to timing issues, robbing your kart of precious power. This washer promotes stable flywheel operation, ensuring consistent magneto firing for instant throttle response—key for overtaking maneuvers.

• High-strength material withstands heat and torque
• Prevents axial play, optimizing energy transfer to the drivetrain
• Eases disassembly for quick trackside adjustments

Kart teams appreciate how such details keep engines humming race after race, reducing downtime and enhancing overall speed potential.
