DSR Dual Valve Spring Kit For LS Engines (Chromemoly Retainers)

For those budget minded street racers, there is now an affordable, top quality, dual valve spring kit featuring lightweight chromemoly retainers, locators, locks and Viton seals that safely provides more performance capability for your LS1, LS2 and LS3 engines.

This DSR spring kit features the popular small diameter, dual valve springs with required seat and open load pressures for most dual purpose hydraulic roller camshaft profiles with maximum lift of .650” at the valve. The dual valve springs used in these DSR kits are the same Associated Spring brand pieces used in many of the current LS drop-in spring packages. This DSR kit comes complete and is ready to easily install into your LS heads.

This high performance, lightweight spring package incorporates US manufactured chromemoly steel retainers, not overseas inferior pieces. Fully CNC machined for use in severe duty applications such as endurance, road racing and marine uses. Hardened spring locators are included and accurately locate the spring assembly to the factory .500" diameter valve guide, preventing scuffing on aluminum cylinder heads.
