These Manley Performance retainers are machined to INTENSE's exacting specifications to ensure proper fit and guide clearance. The steel retainers are 8% lighter than Comp Cam Steel retainers weighing only 11.8 grams each. They are made from "Thru-Hardened" 4140 chrome moly material and then given a black oxide finish. The titanium versions are 11% lighter than Comp Cams titanium retainers and 43% lighter than their Manley steel counterparts weighing only 6.7 grams each. The lighter the valvetrain components, the quicker the engine will rev. And shaving a few grams off the end of the valve is enough to add a few hundred RPM before the engine reaches valve float.

Both the Steel and Titanium versions of these Manley retainers offer more clearance than stock and .045" more than a Comp Cams retainer. They are not milled down but rather produced that way to eliminate any fluctuation in production and to ensure a perfect clearance every time.

Engineered to work with stock or other compatible beehive valvesprings with no machining, these retainers are also compatible with factory valvestems and valve locks.

We also recommend the use of stronger CompCams 105# or CompCams 130# Valvesprings with either of these valvespring retainers choices.

Sold in sets of sixteen.
