5mm Billet Titanium Retainer Kit with 32lbs Dual Valve Springs
Billet Titanium Retainers & 32lb Dual Valve Spring Kit for 5mm Valves
Unlock high-RPM stability and maximum valve train control with the Titanium Retainers & 32lb Dual Valve Spring Kit—engineered specifically for small engine builds using 5mm stem valves. This premium kit is built for performance applications running aggressive camshafts, high-ratio rockers, and elevated RPM ranges.
The lightweight billet titanium retainers dramatically reduce valve train mass while offering the strength and durability needed to handle extreme spring loads and cam profiles. Pairing them with our high-performance 32lb dual valve springs ensures excellent seat pressure, resistance to valve float, and superior control at high engine speeds.
Kit Includes:
(2) Billet Titanium Retainers for 5mm valves
(2) 5mm Valve Keepers / Locks
(2) 32lb Dual Valve Springs
(2) 5mm Lash Caps
Key Features:
Titanium construction for unmatched strength-to-weight ratio
Designed for dual spring setups only—compatible with both 32lb and 38lb dual springs
Ensures stable valve operation at high RPM with aggressive cam timing
Ideal for modified racing engines with upgraded cams or high-ratio rockers
Not for use with stock valves—we recommend pairing with EC 5mm Stainless Steel Valves
