GM Alternator mounting kit LS1 to RB

Pulley, brackets, and hardware to mount LS1 Alternator to all RB engines. Sleek Billet brackets, which provide correct alignment and strength via the rear brace. High tensile hardware and hard anodised pulley for long service life! Very popular upgrade,  and several options on the market, but no other kit provides the rigidity of our design.

This kit eliminates the factory tensioner, for a nice clean look.
