The GMC Safari Rocker Shaft Spring Kit offers a fortified valvetrain by locking each rocker arm in line, helping you keep that power strong mile after mile. The Rocker Shaft Spring Kit is trusted by drivers to maintain a tight clearance that prevents valve float and lets the 4.3 liter V6 purr. If you have a van from the earlier range or the later facelift, the Rocker Shaft Spring Kit fits all Safaris from 1985 to 2005. The Rocker Shaft Spring Kit comprises hardened steel springs and precision spacers to press with a constant load between 70 and 90 pounds, controlling lash and preventing side thrust on the cam followers. This strong grip maintains combustion efficiency, cuts down on wasted fuel and emissions, and enhances the safety margin when a GMC van merges or tows. The more recent GMC units utilize a lighter multi-coil configuration, and this Rocker Shaft Spring Kit provides equal stress distribution, preventing the occurrence of fatigue cracks. The reduced weight allows the engine to rev more quickly, resulting in the Safari's loaded variant climbing grades without the clatter of yore indicative of worn rockers. In the same way as new, the installation of the Rocker Shaft Spring Kit places every rocker in alignment, allowing for valve sealing at highway speed to resist heat and pressure. The Rocker Shaft Spring Kit helps to eliminate bent pushrods and broken arms, giving families, tradespeople, and adventurers the confidence to rack up distance instead of worrying about roadside repairs. GMC owners also like that the kit does not add any special maintenance steps, only the usual oil changes that keep any Safari clean. The Rocker Shaft Spring Kit has thousands of field miles proving it outlasts the heat cycles that destroy normal spacers. With strong GMC construction and exact Safari fitment, this kit stands out from other similar products at an affordable price. Always choose original GMC parts to keep the spirited Safari character in mint condition.
