Offset Dual Valve Spring Retainers (Pair)

The GoParts Offset Dual Valve Spring retainers give small engine builders valve spring seat pressure flexibility by producing an additional .100” installed height. Designed for all GoParts Dual Valve Springs these offset, 10° lock, retainers allow you to tune your valve spring pressure without machining the head or valve. They can be used with our flat or radius locks, GP750-2 or GP642-2, so you can use them on flatheads or OHV engines.
