In Stock. Ships within 1 business day.
GM LS LQ series TYPE 2 "Alternator Only” Bracket and Adjustable Idler system, CNC Machined in the USA from 6061 aircraft grade billet aluminum.
Will work with TRUCK BALANCERS ONLY.
Mounts the alternator on the top of driver’s side of the motor
Works with the 145 or 160 amp truck alternator, or the 105 amp LS1 F-Body alternator
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.
The distance from the engine center-line to the outside of the alternator is only 14.5”.
This setup retains the factory truck active tensioner. It is compatible with the aftermarket tensioners also.
It can also be used to drive the alternator directly off the crank if using an electric water pump. Flip the slotted idler block over and it can be used as a tensioner on the top of the belt (see photo). Will work with the Meziere electric pump
Designed to clear the control arms in the 2nd Gen. Camaro and fit 62-67 Chevy Nova's.
You only need to supply the 68.5" 6-rib 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 5060495 (49.5")
If you are running an undersized balancer, you will need a shorter belt than listed.
