Product Description
TSP LS7 7.0 .660" POLISHED Dual Spring Kit with Valve Springs, Titanium Retainers, and Shims
The all-new 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: Spring Seats, Valve Seals, polished Dual Springs, Titanium Retainers (utilizes GM factory valve stem locks, not included), and Shims for proper install height; This kit will NOT use the TSP integrated seat and seal. The seat and seal will be separate.
