1.570 Dual Valve Springs CT 1200 Series (16)

The 1.570 Dual Valve Springs CT 1200 Series (16) from PAC Racing Springs is a high-performance valve spring set designed specifically for circle track racing applications. These springs are essential for racers who require reliable valve actuation and consistent lift control, particularly in high-stress environments typical of competitive racing.

Each spring features a 1.570-inch outer diameter and a spring rate of 743 lb/in, which is crucial for preventing valve float at high RPMs. The dual spring design incorporates a primary outer spring paired with an inner helper spring, effectively eliminating resonance issues and providing progressive rate characteristics that enhance valve control during aggressive cam profiles.

These valve springs are ideal for circle track racers, including those competing in short-track stock car events and modified or crate engine classes. With a coil bind specification of 1.055 inches, they are precisely calibrated to maintain performance and minimize wear on valve train components throughout the racing season.
