LS Alternator Bracket and Adjustable Idler System

GM LS Alternator Only Bracket and Adjustable Idler System

GM LS LQ series Billet “Alternator Only” Bracket and Adjustable Idler system, CNC Machined in the USA from 6061 aircraft grade aluminum.

This bracket allows you to mount your alternator on the driver’s side of the motor and gives you the choice of using the 105 amp LS1 F-Body alternator or running the cheaper, more powerful 145 amp truck alternator!

Our bracket places the alternator below an LS1 style intake — lower than any other bracket available! The included idler pulley increases belt wrap on both the crank pulley and alternator pulley, and guarantees you won’t sling a belt off. With the Billet Speed alternator bracket, the distance from the engine center-line to the outside of the alternator is only 16”.

This setup retains the factory active tensioner. It can also be used to drive alternator directly off the crank if using an electric water pump. The idler block can be used as a tensioner.

Designed to work with all three LS balancers without spacing the water pump.

You only need to supply the belt (1740mm, Advance Auto part number 685K6 or 6PK1740). If you are using an electric water pump, the belt you will need is a Dayco 5060468.
