Our EC Billet Titanium Retainers and Dual Valve Spring Kit for 6mm Valve Stems.
Lightweight Retainers reduce weight and improve valvetrain stability. The New Titanium combines lightweight with superior durability for the most stable valve train for high RPM engines running aggressive cam profiles or high ratio rockers. Our billet retainers are lightweight but very strong and durable. Lash Caps Not Included.
Do not use dual valve springs with stock valves. We recommend using our 6.5mm Stainless Steel Valves with a 6mm Undercut Tip for the Dual Spring setup.
R-44 32mm(Stock Exhaust) +.100 Longer SS Valve
R-45 35mm(Stock Intake) +.100 Longer SS Valve
R-46 37mm +.100 Longer SS Valve
Valves are sold separately.
Comes with 6mm Valve Keepers/Locks
