Description

The Texas Speed & Performance TSP .660" Polished Dual Valve Spring Kit is designed to offer excellent valvetrain control for aggressive hydraulic roller camshafts. This kit features American-made PAC Racing polished dual valve springs with titanium retainers and a patent-pending Precision Race Components integrated seat and seal.

Key specifications include a maximum spring lift of .660", an install height of 1.810", closed spring pressure of 160 lb. at 1.810", and open spring pressure of 415 lb. at .660" lift. The springs are polished by PAC to increase overall life and reduce fatigue without losing pressure.
