Top: I.D. = 0.545  Bottom: O.D. = 1.120, I.D. = 0.765

These are a MUST for engines with over 300rwkw. Our springs help eliminate valve float, which causes power loss. Valve float can also damage valve stem seals, collets and retainers.

Our springs are a simple drop-in set up designed to work with stock retainers & locks, however we recommend using Titanium Retainers for vehicles with over 500rwkw.
