The Buick Skylark Variable Timing Sprocket lets the engine tailor camshaft timing for stronger torque or higher rpm power, giving drivers flexible performance. This Variable Timing Sprocket features multiple keyways in the crank gear plus precisely machined slots or offset bushings on the cam gear, so builders can advance or retard valve events by a few degrees instead of being stuck with factory marks that may drift two or three degrees. By advancing the cam, the Variable Timing Sprocket opens intake valves earlier and boosts low-end pull, while a slight retard keeps them open longer for top end horsepower, allowing up to fifty horsepower to be recovered on tuned motors. Because accurate alignment is vital, the system is always installed as a complete set with fresh chain, guides, and tensioners on overhead cam versions to maintain proper mesh and silence in modern Buick powerplants. Earlier Skylark editions relied on basic single-key sprockets, but later ones adopted the adjustable Variable Timing Sprocket, the chief difference being the built-in adjustment hardware that removes the need for external degree wheels once set. Thanks to this upgrade, Buick loyalists enjoy stock reliability with performance cam precision in their beloved Skylark models, and every Variable Timing Sprocket continues to safeguard smooth timing while inviting future tuning freedom.
