2008 Hummer H2 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.

Sprocket Made From High Alloy Material. Sprocket Teeth Are Heat Treated. Precision Tooth Form To Assure Proper Chain Engagement, And Precise Keyway To Tooth Timing.

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.

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.

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).

With the backing of an industry-leading two year or 60,000 mile parts and labor warranty, each Dayco timing chain kit includes top-grade timing chains, precision machined crank sprockets and cam sprockets, tensioners, high-grade plastic guides, seals and VVT solenoids and cam phasers if the application calls for it.
