TSP .660" POLISHED Dual Spring Kit w/ PAC Valve Springs, Titanium Retainers, & PRC Integrated Seat/Seal
TEXAS SPEED & PERFORMANCE
The polished TSP .660" spring kit featuring PAC valve springs is the newest offering in valve spring technology offering the latest processes and material for maximum spring life. Â PAC Racing is a leader in valve spring technology, so it was only natural to team up with the best in the valve spring industry for our latest offering in a valve spring kit! Â We have developed a .660" dual spring kit with the help of PAC Racing that still offers excellent valvetrain control, even for the more aggressive hydraulic roller camshafts. Â These valve springs will offer excellent durability and stability and will work well with factory-style lifters. Â PAC polishes the valve springs, which helps to increase the overall life of the springs. Â This greatly reduces the chances of spring fatigue and failure. Â PAC's polishing process is completed without losing any pressure in the valve springs, so you maintain all of the capabilities of the non-polished version.
Kit includes the following items:
- American-Made PAC Racing Polished Dual Valve Springs Rated to .660" Lift
- Patent-Pending Precision Race Components Integrated Seat/Seal for Dual Valve Springs
- Titanium Retainers
