International / Spartan HTB-400 Suspension "Track Box" Axle Shims
Track box axle shims are used to make small but important alignment adjustments in heavy duty truck suspensions. They help fine tune how the axle sits in the track box, which can make a noticeable difference in how the truck handles and tracks on the road. These shims are often added after suspension work or ride height changes, when things no longer line up quite the way they should. Designed for specific applications, they offer a straightforward way to bring everything back into balance and keep steering and handling feeling more controlled.
