Chevy SB SWP Alt Bracket

The Chevy SB SWP Alt Bracket from MARCH PERFORMANCE is a precision-engineered alternator mounting solution specifically designed for small-block Chevrolet engines utilizing serpentine wet pump (SWP) drive systems. This bracket addresses the challenge of integrating modern, high-output alternators into classic small-block architectures without compromising underhood space or reliability.

Manufactured to exacting tolerances, this bracket ensures correct pulley alignment and belt tension throughout the accessory drive system. Its design takes into account the unique geometry of small-block Chevy cylinder heads and timing cover surfaces, eliminating the need for custom fabrication. By maintaining proper belt tracking and load distribution, the bracket helps prevent premature wear on serpentine belts and reduces stress on alternator bearings, which is crucial for high-RPM builds or extended highway driving.

Enthusiasts building small-block Chevrolet engines, ranging from 283 to 400 cubic inches, will find this bracket particularly beneficial, especially when upgrading to higher-output alternators. Its compact and lightweight design (3.32 lbs) minimizes parasitic weight while providing the necessary rigidity for effective engine vibration isolation.
