Chevrolet Silverado Variable Timing Sprocket
The Chevrolet Silverado Variable Timing Sprocket lets the truck's camshaft hit precise angles so the engine delivers strong power across the rev range. Working with the timing chain, crank sprocket and tensioner, this Variable Timing Sprocket carries clearly etched marks that align cam and crank, and while that simple alignment satisfies stock builds, performance setups gain far more accuracy by using a degree wheel and the sprocket's built in adjustment options. Some versions provide multiple keyways in the crank companion, others rely on offset bushings or slotted cam holes. And both styles allow drivers to advance or retard cam timing by up to several degrees, trading early opening intake events for extra low end torque or delaying closure for greater high rpm horsepower. Because the chain, gears and guides stretch and wear together, drivers recommend replacing the Variable Timing Sprocket in a complete set to keep valve timing tight and avoid the 50 horsepower losses that even a two degree error can cause. Over the years Chevrolet refined this Variable Timing Sprocket system for successive Silverado engines, and Chevrolet owners note that every Silverado still depends on the same core principle, a precisely indexed Variable Timing Sprocket that maximizes output without sacrificing everyday drivability.
Each OEM Chevrolet Silverado Variable Timing Sprocket 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.
