Ingalls 38725/38720 Rear Camber Kit Install Tips


September 2016 updateAnnouncing The New Ingalls 38727 Spherical Adjustable Camber & Toe Kit


The Ingalls rear arm kits come disassembled. In each kit are two tubes and four bushings. Take note that one arm may be longer than the other, and the bushings are all different. There are wide- and narrow- bushing collars, and silver and black nuts (signifying right- or left-hand threads).

On 38720 kits for 1999-03 TL, 2001-03 CL, and 1998-02 Accord, the arms are the same length but there are different size bushings to pay attention to. Read the included instructions or compare to the stock arms to assemble correctly. On a 38725 kit (for the 2004-08 Acura TSX, 2004-08 TL, and 2003-07 Accord models) I remember this phrase when assembling: “Short and fat; tall and skinny.” This helps me remember that the wider bushings go on the short arm, and the narrow ones go on the long arm.

Screwing the bushings into the tubes in is usually easy, but the threads can get hung up a but. A little extra turning force can be had using gloves instead of bare hands, but if that is not enough, you will want to inspect the threads.

We have seen threads come out of the box with pieces of slag that will prevent assembly. These bits are easily removed with a small pick.

If the kits are mishandled in shipping, a thread can become damaged. It will look like it is flattened or folded over a bit. A small file will reshape the thread and allow assembly.

If the threads on the bushings look fine, check insde the tubes for debris. You typically won’t see damage here, but slag can be a problem. Again, pick out any visible obstructions.

Some people have cited corrosion causes the bushings to seize in the arms over time. We recommend a high quality anti-seize lubricant to stave of rust.

When assembling the kit, we suggest putting the bar length to exactly the same length as the stock arms with the same amount of threads on each side of the bar. To do this, we suggest these steps:

  1. Install the threaded bushings all the way against the tubes.
  2. Put a bolt through both the stock arm and corresponding Ingalls arm on one side.
  3. Spin the Ingalls tube while holding the opposite bushing steady. This expands both bushings out at the same rate.
  4. Expand the tube until you can put another bolt through the opposing end.

Don’t tighten the jamb nuts before the arms are installed in the car. Also, we recommend doing one arm at a time. Remove and replace one, then another, then move to the other side of the car. If you remove both arms it can allow extra movement that makes it more difficult to install the Ingalls arms.

The short arm with wide bushings goes directly under the shock mounting, and the longer arm with narrow bushings is the “Toe” arm that mounts on the hub-carrier’s rearward stud. If you’ve installed the bushings on the arms correctly, you can’t mix them up. Here are torque specs if you need them.

Once installed, make sure all is tight and head off to get an alignment!
