Description: GM LSx "Alternator Only" Bracket and Adjustable Idler System Proudly CNC Machined in the USA from Billet 6061 aircraft grade aluminum. ***If you are running a Corvette or Camaro LS1 Balancer, make sure to specify when ordering! You will be sent TRUCK hardware/ spacers by default.***Designed to work with all three LS balancers without spacing the water pump. We provide different length spacers / bolts depending on which LS harmonic balancer you are using. You will be sent TRUCK hardware/ spacers by default. Send us a message if running corvette or camaro LS1 balancer.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 alternatorCompatible with any LS series engine, because everything bolts to the cylinder head. This includes LQ4, LQ9, LS1, LS2, LS3, LSX, and more.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 (slot on the bottom) and it can be used as a tensioner on the top of the belt (see photos). Will work with the Meziere electric pump.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 16”. If you need narrower, see the Type 2 bracket which is 1.5" shorter.This setup retains the factory active tensioner. Make sure you have the same tensioner as the balancer you are using (Truck, LS1 or Corvette). It is compatible with the aftermarket tensioners also.Important Note: this bracket will not work in a 4th Gen. F-Body Camaro with F-Body/LS-1 Balancer. See our fixed idler version for this vehicle. WILL NOT WORK in a 3rd Gen. CTS-VImportant notes about Corvette accessory drive :The coolant temperature sensor needs to be relocated to the passenger side head when using the Corvette balancer / accessory drive.Corvette spacing will not work with tall aftermarket valve covers.You only need to supply the 68.5" 6-rib drive belt (1740mm, Advance Auto part number 685K6 or 6PK1740).If you are using an electric water pump, the belt length is 50" for stock diameter balancer.If you are running an undersized balancer, you will need a shorter belt than listed.Important Note: this bracket will not work in a 4th Gen. F-Body with F-Body/LS-1 Balancer. See our fixed idler version for this vehicle.
