S&S Cycle Compensator Spring Kit M8 Twin Cam

The S&S Compensator Spring Kit was engineered as a premium drop-in upgrade for late-model, high-output Harley-Davidson® Twin Cam and M8 engines to tame the torque and quiet the clatter. This American-made steel alloy spring is 200% stiffer than the weak factory original unit it replaces, delivers a 50% increase in system pre-load force and a 32% boost in torsional stiffness. Our spring provides massive torque spike protection to shield your clutch and transmission.

Beyond heavy-duty drivetrain protection, this drag-strip-proven upgrade noticeably smoothes out low-RPM roll-on throttle response, improves engine starting, and eliminates annoying startup/shut-off clatter. It is the ultimate, cost-effective way to silence a noisy primary drive and ensure your compensator retains its stiffness, even under the most extreme, high-temperature riding conditions.

• 200% stiffer than the OEM H-D small compensator spring that it replaces. *A
• Increases pre-load and torsional stiffness of the compensator system.
• 32% increase in torsional stiffness through the range of compensator ramp travel. *B,C
• 50% Increase in system pre-load force. *C
• Smoothes low-rpm roll-on response / feel.
• Provides better torque spike protection for all downstream drivetrain components (clutch, transmission, etc.). A great upgrade for bikes paired with high-displacement / high output Late-Model Twin Cam and M8 engines.
• Improves engine starting. Controls compensator shutter and reduces clatter and noise during engine startup / shut-off.
• Helps quiet worn, noisy primaries.
• Disclaimer: The S&S compensator spring is not a fix for excessively worn or damaged compensators.
• Drag strip proven.

Direct upgraded replacement for 10-24 CVO, 11-24 Touring, 12-24 Dyna/Softail/Trike. Also fits 07-12 (Including 06 Dyna) Twin Cam models that are equipped with the updated Screamin Eagle compensator.

• NOTE: Will fit 2007-2010 equipped with Screaming Eagle Compensator, does not fit stock compensator on these models
