Manley Sport Compact - Pro Series Spring and Retainer Kits: Manley Pro Series Spring and Retainer Kits are matched sets perfect for your high revving Sport Compact.

*Valve Springs*
Manley Performance valve springs are specifically designed to withstand the rigors of today's aftermarket Sport Compact camshafts and properly control the valve train in these high revving Sport Compact engine applications. This means utilizing only the best, super clean chrome silicon high tensile strength steel alloy and performing classified heat treatment and shot peen processing to insure the ultimate fatigue life and limit load loss.

*Titanium Retainers*
Manley titanium retainers are manufactured in the very best dual spindle CNC machines to exacting tolerances rendering a superior jewel-like finish. We use rugged and certified, heat treated aerospace grade titanium bar stock.

Retainer angles are held to within 6' (minutes) (this is a tenth of a degree) and installed heights are held to within .005"!

Titanium retainers are a must for your high RPM Sport Compact engine. Their lighter mass allows the tuner to turn higher engine speeds and still avoid dangerous valve float; without sacrificing reliability.
