LMM Duramax Timing Chain Kit 2007-2015

Overview

This is a timing chain service kit for the Chevrolet, GMC LMM Duramax diesel (2007-2015). Built to OEM specification and engineered as a direct-fit replacement for a professional-grade LMM Duramax repair or service. Every order ships fast and is backed by our support team.

What It Does & How It Helps

The timing chain keeps the crankshaft and camshafts in sync. As the chain stretches and its guide rails and tensioner wear, you get a cold-start rattle and eventually a timing-correlation code — and on an interference engine a jumped or broken chain means bent valves. A complete chain kit, with the chain, guides, tensioner and sprockets where included, restores tight, quiet valve timing and protects the engine from a very expensive failure.

What's Included

• a timing chain, guide rails and a chain tensioner as specified
• the sprockets and seals where the kit includes them
