Features & Benefits
- Complete Four-Piece Gen V LT Timing Kit: Michigan Motorsports packages the primary timing-drive components needed for compatible L83, L86, and LT1 engine service in one matched kit. Replacing the chain, tensioner, crank sprocket, and phaser sprocket together helps simplify parts selection when the front of the engine is already apart.
- Michigan Motorsports Heavy Duty Timing Chain: The included heavy duty timing chain replaces GM #12646386 and #12586482 for compatible Gen V LT timing applications. It provides the critical connection between the crank sprocket and phaser sprocket during camshaft operation, making it a practical replacement during timing service or internal engine upgrades.
- Michigan Motorsports Tensioner and Crank Sprocket: The kit includes a Michigan Motorsports timing chain tensioner replacing GM #12630107 and crank sprocket replacing GM #12713934. Replacing these components with the chain supports a more complete timing-system refresh instead of reusing existing parts during major engine service.
- Genuine GM Phaser Sprocket Included: A Genuine GM phaser sprocket, GM #12623368, completes the camshaft side of the factory-style VVT timing assembly. This gives builders an OE GM phaser component while pairing it with Michigan Motorsports timing service components for the rest of the primary drive.
- Ideal for Camshaft and Front Engine Service: This timing kit is a strong choice when performing camshaft installation, oil pump service, front cover repairs, engine rebuilding, or high-mileage maintenance. Replacing the major timing-drive components together can help prevent repeat labor after the engine has been reassembled.
