MIP Bypass1 pistons are fully customizable and allow you to control your shocks rebound speed. MIP Bypass1 Pistons are also Dyno Tuned to ensure they match the compression characteristics of the stock pistons!

Bypass1 Pistons combined together with MIP valves allow you to control and maximize your cars shocks performance based on the valves you use. Thicker valves generate a slower rebound and thinner vales get you quicker rebounds. Mix and match valves together and find the best set up for you and your car!

MIP Bypass1 pistons are being used by some of the top racers in the world, including Adam Drake and Ryan Maifield.

You can drill out Bypass1 Pistons to your specifications. Bypass1 Pistons feature 1.3mm pre-drilled holes which allow you to easily drill them out to custom hole sizes.
