TSP Gen 5 2015+ LT4 .660" Dual Spring Kit w/ PAC Valve Springs and Titanium Retainers #199-LT4660SpringKitThe 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. 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 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. This greatly reduces the chances of spring fatigue and failure.Kit includes: Spring Seats, Valve Seals, Dual Springs, and Titanium Retainers (utilizes GM factory valve stem locks, not included)Specs:Install Height: 1.810"Closed Spring Pressure: 160 lb. @ 1.810" Installed HeightOpen Spring Pressure: 415 lb. @ .660" liftMaximum Spring Lift: .660"Coil Bind 1.015"
