Alternator Mnt Kit GM LS Engines w/Moroso Elc W/P

The Moroso Alternator Mount Kit for GM LS Engines with Moroso Electric Water Pump is a driver-side mid-mount bracket solution engineered for LS engine builds that incorporate electric water pump configurations. This aluminum bracket accommodates 103mm alternators and provides the precise mounting geometry needed to integrate Moroso-style electric water pumps without conflicts or clearance issues. For engine builders and performance enthusiasts running LS platforms, the alternator mount kit solves a critical integration challenge: standard alternator brackets often interfere with electric water pump installations, forcing costly workarounds or custom fabrication. This kit eliminates that friction.

Constructed from aluminum and finished in natural (bare) state, the bracket is lightweight and corrosion-resistant, making it suitable for street cars, race vehicles, and engine swap projects alike. The mid-mount design positions the alternator in a location that maximizes engine bay space efficiency while maintaining proper belt tension and pulley alignment. At 1.73 lbs, it adds minimal weight while delivering the structural rigidity required for reliable electrical generation across a wide RPM range. The compact footprint—3.5 x 3.3 x 8.8 inches—fits tight engine compartments without excessive bulk, critical for custom LS installations where clearance to other components is limited.

This kit is essential for anyone building a modern LS engine package with an electric water pump conversion. Whether you're assembling a street rod, a track car, a swap into a classic chassis, or rebuilding a high-performance truck engine, the Moroso kit eliminates guesswork and ensures compatibility between critical cooling and charging subsystems. It's particularly valued in tight-fitting applications where factory mounting points don't translate to the new configuration. The driver-side orientation works with standard LS block configurations, making it a straightforward bolt-on solution that saves hours of custom bracket fabrication and testing.
