GMC Yukon XL Engine Timing Parts

Since 1921, Cloyes has been the trusted leader in automotive timing systems, delivering premium-quality solutions. A timing chain tensioner maintains appropriate tension in the timing chain. Depending on design and application, Cloyes engine timing chain tensioners can use spring tension or hydraulic pressure to properly tension the chain for optimal performance. To ensure total timing system integrity, Cloyes recommends replacing the chain along with the tensioners, guides, and sprockets during service. Trusted by professionals for over a century & backed by an industry-leading Warranty (limited) and technical support.

Since 1921, Cloyes has been the trusted leader in automotive timing systems. As a critical component of the engine’s timing system, the crankshaft sprockets work in unison with the timing chain, tensioners, guides and other sprockets, to ensure precise timing. Cloyes engine timing crankshaft sprockets are precision-tooled with exact tooth geometry and a perfectly matched bore, off-set and timing index for superior fit, reliability, and long-term performance. To ensure total timing system integrity, Cloyes recommends replacing the chain along with the tensioners, guides, and sprockets during service. Trusted by professionals for over a century & backed by an industry-leading Warranty (limited) and technical support.

INA Timing Chains are designed to meet or exceed OE quality and performance. All our chain Plates and Pins are heat treated to precise hardness for maximum performance and durability.

Engine Variable Valve Timing Solenoids regulate oil flow to the cam phasers that change the timing of the camshafts. The desired positions of the camshaft varies with engine speed and load and is calibrated for optimal engine performance, drive quality, and efficiency. They are GM-recommended replacements for your vehicle’s original components. These original equipment solenoids have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

This replacement camshaft adjuster magnet is a direct replacement for a damaged original equipment magnet. Made of quality materials for durability, this part has been tested to ensure a proper fit.

“Cloyes Performance Tensioner Elimination GM LT Engine Timing “”Z”” chain det eliminates the factory tensioner while maintaining tunable accurate timing for VVT-equipped LT engines. By removing the factory tensioner, this kit eliminates chain slack and potential failure. The “”Z”” chain offers superior strength and durability for VVT LT engines, reducing the risk of chain stretch or fatigue. The combination of Cloyes TRUE Roller “”Z”” Chain and precision-machined sprockets ensures a center distance corrected timing drive for extreme performance on VVT-equipped LT engines.”

“Billet Crankshaft Sprocket Has Three Keyways for +/- 4 Degrees Adjustability. Both Billet Steel Sprockets are Heat Treated for Durability. TRUE Roller 0.250″” Roller Diameter Chain for Reduced Friction. Includes Captured Needle Camshaft Sprocket Thrust Bearing to Minimize Block Thrust Surface Friction. 3-Piece Sets Hand-Matched to Qualify the Correct Center Distance and Minimize Runout.”

The combination of Cloyes TRUE Roller chain, and precision-machined sprockets ensures a center distance corrected timing drive for reliable performance on VVT-equipped LT engines.

Tensioner Elimination Kit for GM LS Engines Equipped with VVT. Kit Replaces the Chain and Crankshaft Sprocket to Tighten the Chain Fitment and Eliminate the Factory Tensioner.

The variable valve timing (VVT) system allows the engine control module (ECM) to regulate the intake and exhaust valve phase angle providing the most optimal engine volumetric efficiency under all engine operating condition to control tailpipe emissions and engine efficiency. Variable valve timing is an emission control device and although there are various methods of operation, the typical device is regulated by oil control valves, actuator solenoids and camshaft phasers.

This replacement VVT oil control valve is a direct replacement for a worn or leaking original equipment valve. Made of quality materials for durability, this part has been tested to ensure a proper fit.
