Prevent the dismount of your springs without having to change spring rates. Our Helper Springs are specifically designed to have a minimal effect on the spring's rate of retention on the coilover perch while the shock is under negative or zero load, also known as droop travel. It is ideal to run helper springs on setups where you cannot pre-load the main spring due to height issues or when experiencing springs coming loose from the coilover perch.
