Frequently Asked Questions
SKU: 199-ISSPACPOL660SpringKit
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. 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! 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. These valve springs will offer excellent durability and stability and will work well with factory-style lifters. PAC polishes the valve springs, which helps to increase the overall life of the springs. This greatly reduces the chances of spring fatigue and failure. 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
*Our dual valve spring kit utilizes GM factory valve stem locks, which are not included
*Will not work on LS7, LS9, any Gen 5 LT1/4 engine applications, and most aftermarket cylinder heads with bronze guides
