GM Alternator Bracket Bolt Kit - 6pt.

The ARP GM Alternator Bracket Bolt Kit - 6pt. (part number 130-3302) is a precision fastener set engineered for small-block and big-block Chevy V8 engine builds where durability and corrosion resistance are non-negotiable. This three-piece hex head bolt kit includes integrated washers and combines ARP's chromoly steel construction with black oxide finish, delivering the strength required for high-performance alternator mounting applications while resisting rust and oxidation in harsh engine bay environments.

Chromoly fasteners offer superior tensile strength compared to standard steel, critical for maintaining proper clamping force on alternator brackets during sustained high RPM operation. The black oxide finish provides corrosion protection in wet or high-temperature conditions common in engine bays, while the six-point head geometry reduces rounding risk during installation—essential when working in tight underhood spaces where access is limited. Integrated washers eliminate the need for separate hardware, streamlining assembly and reducing parts count on the build.

Builders and engine rebuilders working on carbureted or fuel-injected Chevy V8 platforms rely on bracket fastener kits like this for bolt-on alternator upgrades, restorations, and performance builds. Whether you're securing an OEM alternator to a custom engine bay or installing aftermarket charging systems, this kit delivers the fastener integrity that prevents bracket failure under load. ARP's reputation in the fastener market stems from precision manufacturing and material selection—specifications that translate directly to long-term reliability on the street or track.
