Star .655 Lift Twin Cam Valve Spring Kit with Titanium Retainers
The valve train upgrade your high-lift Twin Cam build demands.
 
Part Description
Built for Twin Cam engines running high lifts like those with Star Racing's P38 Lightning 615 and Thrasher 650 camshafts. This spring kit is engineered to handle the demands of aggressive lift profiles without compromise. Lightweight titanium retainers reduce reciprocating mass for cleaner valve control at high RPM, while the race-spec springs deliver consistent seat pressure and reliable return across the full lift range — whether you're building for the street or the strip.
 
Supports up to .655 lift.
 
Designed to pair directly with the Star P38 Lightning 615 (TC615C) and Star Thrasher 650 (TC650C) camshafts.
 
Fitment: Twin Cam CVO 007+
