The Variable Timing Sprocket of the GMC C1500 allows the truck to hit its optimal power targets with precise cam adjustments, enhancing performance and reliability. This Variable Timing Sprocket features multiple indexed keyways along with offset bushings and elongated slots. This enables builders to advance or retard the cam a few critical degrees. Thus, one can extract more torque from every GMC powerplant without fear of detonation or valve clash. Whether installed on an early carbureted C1500 with a single fixed keyway or a later fuel injected C1500 with slot style gears, the Variable Timing Sprocket is a direct match that drops in with the factory chain, guides, and tensioner system. It provides a stock fit while allowing custom timing. The sprocket comes with a degree wheel to fix the two degree errors that commonly steal horsepower. Now you can be confident that your GMC will deliver the punch that the spec sheet promised. By a careful adjustment of the Variable Timing Sprocket, the cam is advanced. This aids stronger pulling power at low rpm. Hence, a loaded C1500 will surge ahead with less throttle. Therefore, this saves fuel and reduces stress on the automatic transmission. When the fun of the weekend demands higher revs, retarding the Variable Timing Sprocket shifts the power band upward, allowing the sporty C1500 to breathe free at the top end and pass with confidence. The internal mechanism has been praised for its durability as the hardened steel teeth of the Variable Timing Sprocket will neither suffer from stretch nor wear, maintaining accurate valve timing and preventing pistons from mistimed contact. Due to the fact that the GMC factory computers read the corrected cam sensor signal without reflash, the Variable Timing Sprocket works with stock electronics. GMC owners who want their vehicles to start consistently on a cold morning will appreciate the benefit of this, and a single Variable Timing Sprocket upgrade has been known to improve the drivability, efficiency, and safety of a range of C1500 trims.
