Ferrea E11017 Titanium Valve Retainer Set Of 24, Dual Spring E11017 (90-06 NISSAN 300ZX)

These VG30 Titanium Retainers are 40% less weight than a stock Nissan 300zx retainer and twice as strong. By reducing the weight of the valve train it will improve the follow up response of the cam lobe @ higher RPM's. Also the lighter weight will allow you to rev the engine higher. Will only work with Ferrea Dual Valve Springs
