DSR 8MM Dual Valve Spring Kit - (Chromemoly Retainers)
For those budget minded street racers, there is now an affordable, top quality, dual valve spring kit featuring lightweight chromemoly retainers, hardened locators, machined valve locks and Viton seals that safely provides more valvetrain control.
This DSR spring kit features the popular small diameter, dual valve springs with the 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 performance spring packages. This DSR kit comes complete and is ready to easily install into your heads.
This high performance, valve spring package incorporates US manufactured, FEA designed, chromemoly steel retainers, not inferior overseas junk. Fully CNC machined for use in severe duty applications such as endurance, road racing and marine uses. Hardened, fully machined spring locators are included and accurately locate the spring assembly to most aftermarket heads with .562" diameter valve guide, preventing scuffing on aluminum cylinder heads. High strength, hardened "machined" (not stamped) steel valve locks are provided for valve stem holding reliability. Premium quality, Viton steel shell valve stem seals are included for proper valve stem lubrication and oil control.
This is our most popular direct replacement spring kit for AFR "Renegade" series heads, Twisted Wedge 11R heads and certain ProMaxx heads. Will fit many other aftermarket cylinder heads with 8mm valve stems so check your casting dimensions for verification.
