2015 GMC Sierra 3500 HD 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.

ACDelco GM Original Equipment Engine Timing Damper Kits remove unnecessary slack from the timing chain to help prevent chain rattle and excessive component wear, and are GM-recommended replacements for your vehicle’s original components. These original equipment engine timing damper kits contain components that will provide the same performance, durability, and service life you expect from General Motors.

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.

“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. 3-Piece Sets Hand-Matched to Qualify the Correct Center Distance and Minimize Runout.”

“Billet Crankshaft Sprocket Has Nine Keyways for +/- 8 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.”

Cloyes Performance Tensioner Elimination GM LT Engine Timing Set 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 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.

INA timing chain kits include all essential components to ensure that the repair is done right the first time. Each kit contains all necessary chains, tensioners, and guides. In certain applications the kit also contains the necessary gears and sprockets, along with a specially formulated, high performance, chain additive uniquely made for Schaeffler by Liqui Moly. The chain additive helps reduce friction during the break in period and reduces run-in wear by up to twenty percent.

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.

GM Genuine Parts Engine Variable Valve Timing Solenoids are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These 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. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

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.

The variable valve timing sprocket is key to ensuring an engine’s performance and clean running. Replace a worn factory VVT sprocket with this quality engineered sprocket to restore lost performance. Designed to install and perform like the original.
