We offer a mixture of two different Haldex automatic slack adjusters, ABA and S-ABA. The ABA
(Automatic Brake Adjuster) is the original design most people will have on their truck or trailer.
It has a pointer on the control arm for proper positioning. The S-ABA is Haldex's latest design
that has no pointer. The control arm tab of the S-ABA (Self-Setting Automatic Brake Adjuster) slack
adjuster can be placed in just about any position you need.
The two adjuster types can be interchanged, but you should use two of the same type on an axle
to maintain even braking.

How do I measure my air brake slack adjuster?
The first step to determining which air brake
slack adjuster you need is to measure the diameter of the camshaft at the splines. You will then need to count
the splines. Finally, measure the distance from the center of the camshaft hole to the center of the clevis
pin hole. This measurement is referred to as the span in the list below.
You'll also need to be aware of any offset from the center line of the slack adjuster arm
to the center of the brake chamber push rod. Most of the slack adjusters listed below are
not offset. Offsets will be listed in the details for each slack.
A Word of Caution:
Do not mix slack adjuster brands on an axle. For example, don't have a Haldex automatic slack adjuster on one side and
a Gunite on the other. Why? Each brand has a different way of making the brake adjustment, so you will end up
with uneven braking.
