GMC Yukon Variable Timing Sprocket
The GMC Yukon Variable Timing Sprocket lets the engine hit its ideal power band by aligning cam and crank motion with precision. In every Yukon, this device works as part of a matched set of timing chain, guides, tensioner and gears, and replacing the whole set keeps the Variable Timing Sprocket from wearing unevenly. Stock versions rely on simple timing marks that line up the cam and crank, but a performance oriented Variable Timing Sprocket takes accuracy further, using multiple keyways, offset bushings or elongated slots so installers can dial timing within a single degree. That adjustability allows drivers to advance the cam for stronger low end pull or retard it for more top end horsepower, preventing the power loss that as little as a two degree error can cause. Earlier styles offered only fixed alignment, while later adjustable styles of Variable Timing Sprocket give Yukon owners control over where the engine makes torque. Every GMC driver appreciates how the system sharpens throttle feel in the updated models, and GMC recommends changing the tensioner and guides whenever the Variable Timing Sprocket is replaced, ensuring long life and consistent timing in all GMC sport utility engines.
Each OEM GMC Yukon 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.
