Dokili .600'' Drop-In Valve Spring Kit for Silverado, Sierra, Camaro, Corvette TBSS CTS-V GTO LM7 LS1 LS2 LS3 LS6 Car, Truck & SUV 4.8 5.3 5.7 6.0 6.2
Stability
Dokili Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer.
Durability
The unique designed shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life. Because of the unique design, the valve train can handle more RPM and more aggressive cam profiles.
