The SouthSide Machine traction bar shims are made to fill the wedge shaped space between traction bar mounting plate and your bottom U-bolt mount plate , when installing traction bars onto leaf spring suspension vehicles.
This gap is common & can be expected when traction bars are installed onto leaf springs !
Fill this gap and launch Harder & Hooking Tires better too giving you superior take-off.
SSM shims on leaf springs, allow you to adjust your traction bar angle needed in 2 degree increments, giving better weight transfer & rear tire traction on Hard Launches! The SSM Shims also feature the integral ribs on both sides, so they can be stacked without slipping for reaching a higher angle. Easy installation and bolts into place very quickly.
