- DIRECT GM 10SI REPLACEMENT: Bolts straight into factory brackets on Small Block (SBC) & Big Block (BBC) for Chevys (for Camaro/Corvette/C10 Trucks), for GMC, for Cadillac, for Buick. Zero modifications needed
- SELF-ACTIVATING & RELIABLE: Starts charging at 1,000 RPM (rev once after install—done!). Precision voltage regulator maintains 14.2V (±0.5V) even in Death Valley heat or Alaskan cold
- BUILT FOR AMERICAN MUSCLE: Industrial-grade copper windings, triple-sealed bearings & Pro-spec diodes. outlasts stock units 3:1. Looks stock, performs like a beast
- POWER YOUR HOT ROD UPGRADES: 105A output (+40% over stock) handles electric fans, killer stereos, and off-road lights. No more dimming headlights at idle!
- TIP: Always make sure your wiring (especially the main charging wire) is upgraded as required to carry the appropriate current
