Chevrolet Silverado Rocker Shaft Spring Kit allows even timing and sealing of valves by fastening rocker arms firmly in place and establishing optimal spring tension to ensure strong compression and smooth power delivery. The kit combines precision rocker shafts with calibrated springs that press the arms against the pushrods and valve stems to instantly take up lash that would otherwise increase as the metal parts wear. The Rocker Shaft Spring Kit minimizes load concentrated on individual studs by squeezing the rockers onto a common shaft, thus reducing the pounding and guarding against pushrod bending resulting from excessive clearance. The first generations on these OHV models applied a single plain shaft with coil springs at either end. The later Silverado editions went to a dual shaft with stiffer nested coils. This meant extra seat pressures near 90 pounds and open pressures topping 200 to fight valve float at higher rpm. Over the decades that the Chevrolet Silverado has evolved, an updated Rocker Shaft Spring Kit has improved metallurgy to resist heat fatigue. Every engine has a Rocker Shaft Spring Kit to help lifters, cam lobes and pushrods keep the intake and exhaust valves closing fully to avoid burnt valves, misfires and piston contact. Drivers' Rocker Shaft Spring Kit fits right into stock Chevrolet architecture.
