TSP Gen 5 2015+ LT4 .660 Dual Spring Kit w PAC Valve Springs and Titanium Retainers Discount

Description
The all new TSP .660 Gen 5 2014+ LT4 .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 uses a proprietary process called nano-peening that increases the residual stress of the wire, meaning that it compresses the molecules together very tight to help the molecular bond hold better. Â This greatly reduces the chances of spring fatigue and failure.
