Isky Cams 7 Titanium Valve Spring Retainers

Widely used in sprint car and Grand National roller cam applications, Isky titanium retainers are 20-40% stronger than all other retainers because they are made from heat treated 100% aircraft quality bar stock. The Isky Super 7 Retainer and Lock system offers a more precise fit than Isky's standard Jumbo 7 degree Lock / Retainer Combo. The Super 7 degree lock is actually closer to an 8 degree taper angle and incorporates a ground finish on the O. D. to exert a greater locking force in the retainer. Valve spring heights are more consistent as a result.
