SDPC SBC 1.250" Z28 Valve Springs - .525" Max Lift

Like all of our high performance valve springs, these Z28 springs are made from the highest quality materials and precision wound to exact specifications. They are a direct drop-in replacement for most small block Chevrolet applications. These springs will provide more open and closed pressure to maintain proper valvetrain stability on high performance cams. Valve spring maximum lift is 0.525". Be sure to check for proper retainer, seal, and guide clearance before installation on all valve springs! Sold Individually or as a set of 16.

NOTE: If using these springs on Vortec heads the guides will have to be machined down. We sell the Vortec head with these springs under part number SD8060A2
