DSR Single Valve Spring 8MM Kit - (Chromemoly Retainers)
For those budget minded racers, there is now an affordable, top quality, single 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 single valve springs and flat wire damper with the required seat and open load pressures for most dual purpose hydraulic flat tappet camshaft profiles with maximum lift of .600” at the valve. The single 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 cylinder heads with 8MM diameter valve stems.
This high performance, valve spring package incorporates US manufactured chromemoly steel retainers, not inferior overseas garbage. 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 a direct replacement spring kit for AFR "Renegade" series heads. May fit many other aftermarket cylinder heads so check your casting dimensions for verification.
