LS3 Timing Cover

The LS3 Timing Cover from Brian Tooley Racing is a precision one-piece aluminum replacement engineered for GM LS-series engine builders and performance enthusiasts. This timing cover eliminates the traditional two-piece design's leak-prone seams, offering a cleaner engine bay aesthetic while delivering superior sealing integrity. Built for street machines, competition builds, and high-horsepower applications, the LS3 Timing Cover is the choice for builders who demand reliability without compromise.

Manufactured from lightweight aluminum, this timing cover integrates a cam sensor port and includes a precision-fitted seal, eliminating the need for additional gaskets or secondary components. The natural finish preserves the aluminum's durability while allowing for custom powdercoating if desired. The one-piece construction reduces assembly complexity and potential failure points inherent in split designs, making it ideal for high-boost turbocharged or supercharged LS platforms where pressure spikes can compromise inferior seals. At 3.855 lbs, it adds minimal weight while providing substantial gains in engine compartment cleanliness and long-term reliability.

This cover fits all GM LS-series engines, including LS1, LS2, LS3, LS6, LS7, and LSX variants, making it a universal solution for engine swaps, restorations, and performance builds. Installation requires basic mechanical skill and standard hand tools; the integrated cam sensor port allows direct mounting of factory or aftermarket sensors without adapters. Ideal for builders transitioning from carbureted small-blocks to modern LS architecture or upgrading existing LS platforms, the LS3 Timing Cover delivers professional-grade sealing in a compact 13 x 3.1 x 14.55-inch form factor that fits tight engine bays.
