Our EC Billet Titanium Retainers fit 5mm Valve Stems and come with 32lbs Dual Valve Springs.

Lightweight Retainers reduce weight and improve valvetrain stability. Our billet retainers are lightweight but very strong and durable. 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.

Do not use dual valve springs with stock valves. We recommend using our 5mm Stainless Steel Valves for Dual Spring Setups.
