Chevrolet Tahoe Variable Timing Sprocket
The Variable Timing Sprocket of Chevrolet Tahoe aids in precise camshaft phasing of the V8 SUV for a balance between power and efficiency. The Variable Timing Sprocket utilizes the timing chain and crank gear to synchronize intake and exhaust strokes. On overhead cam setups, the guides and tensioner should be replaced with every renewal of the set to ensure even loading. Most stock SUVs can make do with just the factory timing marks on the cam gears and crank gears. Nonetheless, the Variable Timing Sprocket may drift a couple degrees. While it might not seem like such a big deal, that couple-degree error can cost the engine roughly 50 horsepower. Consequently, Chevrolet owners who seek performance turn to a Variable Timing Sprocket with multiple keyways, offset bushings, or slotted mounting holes to advance or retard the cam exactly with a degree wheel. Moving the cam through the Variable Timing Sprocket opens the intake valve in advance to build low-end torque, while retarding it delays valve closure for better high-rpm pull so that Tahoe drivers can tailor the power band for towing or high-speed cruising. The main difference from generation to generation is between the single-position sprocket for normal riding and the adjustable type offering fine-tuning. Both types, however, must always be installed as part of a complete chain and gear set to ensure long-term reliability of the Chevrolet Tahoe engine.
