DSR Dual Valve Spring Kit - (AFR Enforcer)
For those budget minded street racers using the Airflow Research "Enforcer" series small block Ford cylinder heads, there is now a more 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 "Enforcer" 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 AFR Enforcer small block Ford 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 the valve guide, preventing scuffing on the aluminum castings. 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.
