Our EC Billet Aluminum 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 Hard Anodized Coating permeates the metal, protecting it from wear, and is chemical resistant. The bright red color adds brilliance when you remove the valve cover for that high-performance racing appearance.

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