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/5th Gen. Camaro BALANCERS ONLY (farthest spacing). See the TYPE 1 Bracket if you are running LS1 or Vette/CTS-V balancers.
Type 2 bracket is 1.5" shorter/narrower than the Type 1 bracket. The distance from the engine center-line to the outside of the alternator is only 14.5” (vs. 16" on the type 1)
Mounts the alternator on the top of driver’s side of the motor
Works with the 145 or 160 amp factory LS truck alternator, the high output 220 or 240 amp truck alternators, or the 105 amp LS1 F-Body alternator. Fits 99-2005 Truck AD230 (small case) and any AD244 (large case) [5.46" lug spacing]. Also Fits 98-02 Camaro CS130 case (5.46")
Works with Electric Water Pumps! It can also be used to drive the alternator directly off the crank if using an electric water pump. The slotted idler can be used as a belt tensioner. Will work with the Meziere and PRP electric pump. Also works with Big Block Chevy Electric Water Pump.
Normally comes with the smooth steel idler pulley, but when you select electric water pump, it will come with the polymer pulley with flanged sides. We recommend the billet aluminum pulley found here for high horsepower/ drag racing applications.
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.
This setup retains the factory truck active tensioner. It is compatible with the aftermarket tensioners also.
Designed to clear the control arms in the 2nd Gen. Camaro and fit 62-67 Chevy Nova's.
The setup comes with the smooth idler pulley pictured if running standard belt driven water pump. It comes with a plastic flanged pulley if selecting electric water pump. You only need to supply the 68.5" long 6-rib drive belt, part number 685K6 or 6PK1740. These are available at your local auto parts store and they should be able to cross reference the part numbers.
If you are using an electric water pump, the belt length is 49.75 or 50" for stock diameter balancers. Use part numbers 6PK1270 or 6PK1265. It is a tight fit. Start the belt on the alternator pulley first, then the main balancer pulley. Last, press the tensioner pulley against the belt and install.
If you are running an undersized balancer, you will need a shorter belt than listed.
