Performance Timing Chain Kit for Cadillac Escalade (2003-2007) 5.3L 6.0L

High-Strength Performance Timing Chain Kit for 2003-2007 Cadillac Escalade (GMT800)

What it Does: The Performance Timing Chain Kit replaces the worn factory timing chain and gears on the 2003-2007 Cadillac Escalade to restore precise camshaft-to-crankshaft synchronization and eliminate ignition timing jitter.

The Stock Cadillac Escalade Timing Chain Slack

Factory single-roller link chains on high-mileage LM7 and LQ9 engines are susceptible to mechanical elongation under sustained heat and load. As the chain slacks, valve events drift out of phase with the crankshaft, generating timing scatter, sluggish throttle response, erratic idle, and false knock signals. Sintered OEM sprockets also experience premature tooth wear, increasing the risk of chain slippage under high-stress conditions.

The Engineering Solution

This direct-fit timing kit features hardened steel sprockets paired with a pre-stretched, heavy-duty link chain designed to resist wear and fatigue. The induction-hardened teeth on both the crankshaft and camshaft sprockets maintain exact backlash tolerances with the 24X reluctor wheel configuration. Designed to meet high valvetrain stress, this set ensures accurate cam phasing, stable dynamic compression, and dependable power delivery across the entire rev range.

What's Included

• 1 Timing Chain
