LWP Deluxe Alt. Bracket

The MARCH PERFORMANCE LWP Deluxe Alternative Bracket (MPP20121) is a passenger-side, high-mount alternator bracket engineered for Small Block Chevy engines running GM 10SI alternators with long water pump configurations. This aluminum bracket features a clear powder coat finish that resists corrosion while maintaining a clean, professional appearance in engine bays where aesthetics matter alongside function.

Constructed from aluminum, this deluxe bracket delivers the strength required for secure alternator mounting while keeping weight low—critical in performance applications where rotating mass directly affects parasitic drag on the engine. The high-mount configuration and water pump mount integration simplify installation by consolidating multiple mounting points into a single, pre-engineered assembly. This design eliminates custom fabrication, reduces assembly time, and ensures compatibility with OEM and aftermarket water pump options designed for long water pump small block installations.

This bracket is built for engine builders, hot rod builders, and performance enthusiasts who demand precision fitment without compromise. Whether you're assembling a street engine, stroker build, or race platform, the deluxe alternative bracket delivers reliable charging system support while freeing up underhood space and improving overall engine bay layout. The kit format means all necessary hardware is included, reducing the risk of missing fasteners or incompatible components during installation.

Small Block Chevy engines with long water pump configurations present unique packaging challenges that require purpose-built brackets. This MARCH PERFORMANCE solution addresses those challenges with engineering precision, allowing builders to focus on other critical systems rather than fabricating custom mounting solutions.
