Chevy BB Alternator Brkt Kit clear powder coat

The March Performance Chevy BB Alternator Bracket Kit with clear powder coat is a passenger-side, mid-mount alternator bracket engineered for big-block Chevrolet engines paired with GM 10SI alternators and electric water pumps. This aluminum construction kit mounts directly to the engine head and water pump, providing a compact, structural solution for high-performance engine bay configurations where factory alternator placement doesn't accommodate modern component packages.

The clear powder coat finish delivers both corrosion resistance and clean aesthetics, protecting the aluminum substrate while maintaining visibility of the underlying material for engine bay inspections. At 3.6 lbs, this bracket adds minimal rotating mass to the engine assembly. The mid-mount configuration relieves stress from traditional upper alternator mounts by distributing load across head and water pump mounting points, a critical design consideration in high-RPM or forced-induction applications where vibration and deflection can compromise component longevity and electrical output stability.

This kit is designed for builders and engine shops restoring or modifying big-block Chevy platforms where space constraints or component interference demands non-standard alternator placement. The compatibility with 10SI alternators—a workhorse unit known for reliable output and field repairability—makes this bracket a practical choice for street and competition builds alike. Installation requires existing head and water pump mounting surfaces; verify fitment against your specific intake manifold, carburettor, or fuel injection configuration before ordering, as aftermarket manifold designs can vary in clearance.
