Check whether there is any damage on the valve stem or eccentric movement or binding. If necessary, remove head for repair. Press new stem seals over valve guide until they are at specified depth. Install keepers in valve stem grooves by compressing spring and placing retainers then drop them in said sequence if need be use grease literally just to stick them down tiny bit of grease will do it this time if needed at all .

GMC Sierra Rocker Shaft Spring Kit

The GMC Sierra Rocker Shaft Spring Kit provides tight valve control and long-lasting compression by restoring proper spring pressure and rocker alignment to the truck's OHV valvetrain. Mounted on the rocker shaft, the kit's new springs put spring tension on each rocker arm against the rocker's pushrod and valve tip, removing excess lash that causes pounding, bent pushrods, or broken rockers. By maintaining seat pressure close to the original 70-90 pounds and open pressure over 200 pounds, the Rocker Shaft Spring Kit prevents valve float that robs power or even allows valves to collide with pistons at high rpm. Earlier GMC V8s had a simple shaft with uniform coil springs, but later Sierra editions have a refined Rocker Shaft Spring Kit with matched pairs of variable-rate coils better suited to the dual demands of intake and exhaust, the main difference being the progressive wind which provides firmer resistance as lift increases. Regardless of year, each Rocker Shaft Spring Kit works in a mechanical fashion and in current GMC applications, provides Sierra owners a simple, long-lasting protection of the engine's breathing system. Installing a fresh Rocker Shaft Spring Kit is a tried and true way to regain a smooth idle, crisp acceleration, and long valve life.

Each OEM GMC Sierra Rocker Shaft Spring Kit we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
