LS Truck Idler Relocation

Idler relocation kit for LS truck engines (4.8, 5.3, 6.0, 6.2).

This kit allows low-profile passenger car intake manifolds to be used with the OEM truck alternator/power steering bracket..

The lower throttle body location on passenger car intakes (LS1, LS2, and LS3) and aftermarket high performance intakes (FAST, MSD, etc.) interferes with the OEM truck idler pulley. It also causes interference with the stock truck water pump. The solution is to cut off the OEM idler support and mount a new idler underneath the alternator. This will also change the belt routing, further eliminating interference.
This kit can be used with Kwik Performance AC compressor brackets, K10472 wide-mount or K10291 high-and-tight. This kit also works with a factory LS3 Camaro belt tensioner (see more info below) mounted in the stock location on the LS3 Camaro water pump.

• New idler pulley
• Zinc coated fastener
• Machined tubular pulley support post

• Stock truck alternator/power steering bracket modified by removing the idler pulley support area. See installation instructions for more details.
• An LS3 Camaro water pump (2010-2015). Truck water pumps will interfere with either a drive-by-cable or drive-by-wire throttle body on low-profile intake manifolds. The late Camaro water pump has the upper outlet exiting the front of the pump on the driver’s side and maintains correct belt spacing with truck harmonic balancers, alternators and power steering pumps.

• An LS3 Camaro tensioner (if not being used with Kwik Performance AC K10472 or K10291). Gates part# 39334
• A new belt is required and a belt length chart is included in the installation instructions.

• Kwik Performance Alt/PS (P-series) bracket (K10611) mounts your truck alternator in the stock location. The power steering pump is tucked in tighter to give greater clearance of A-arms and steering boxes. This achieves the same clearance advantage of smaller pulley on the PS pump without over-spinning the pump. As an added bonus, it moves the attached metal reservoir as well, unlike a pulley swap alone. It requires no cutting of factory bracket and we think the 6061 aluminum construction looks better.
