LS Truck Billet Alternator Bracket

Compatible with: truck/SUV (or LS3/L99 Camaro) crank pulley (ICT# BAL300)

• *Without power steering, a ribbed idler (not included) will be needed. (551528)


• **Alternator: (ICT# ALT300)(will not fit Corvette/CTSV or 2010 up Camaro large bolt pattern alternators), will fit any other LS powered vehicle alternators with any amperage. 145+ amp alternators do not have the provision for the rear bracket.


• When using an iron block, we recommend using our front support bracket to add the 3rd mounting point for the alternator bracket SKU 551921-LS01.


• If needing to extend your alternator harness connection, use ICT# WEALT30-36 (4-pin) or WEALT40-36 (2-pin)


• Made in Wichita, Kansas from aerospace grade, USA produced, billet aluminum


• Includes: front & rear bracket, idler pulley, and mounting hardware


• Belt Length (550K6)

*May require slight grinding on block (see photos) if using a 105 amp alternator (145/160 amp alternators are a direct fit)

**This can only be used on blocks with at least 2 mounting holes on the front of the block. Blocks that only have 1 mounting hole will require drill template 551445 to drill and tap the 2nd M10-1.5mm hole. This hole is in a non-critical part of the block that is away from the cylinder, oil, and water jackets. This bracket only bolts to the front face of the engine block.

This will require a 790K6 (79.0 inch) belt when used with the 551785-3 power steering pump bracket and 105 amp alternator (ICT# ALT300)

If using as an alternator only bracket you will use the ribbed pulley part number 551528 and a 550K6 (55 inch) belt
