Eliminates heat to your shock - A cooler shock results in enhanced suspension performance and extended service intervals. Unlike competitor's products that use metal which retains heat, P3 uses advanced composites that dissipates the heat to the rear. When shock oil overheats, it breaks down and leads to increased wear as well as diminished suspension performance. Extra Bonus: No more heat to your left leg! Made from P3's high-quality composites and epoxies. Save your shocks. Increase your performance. Limit amount of service. Cool your leg. Ride With Confidence. You're #P3PROTECTED.
