SPE 35021 Tandem 1/16" Alignment Shims for Freightliner Trucks [QTY 6 Shims]

Heavy duty spring suspension is the link between your truck’s wheels and its body. These heavy duty truck parts compensate for irregular and uneven road surfaces, so you can be comfortable while on the road. Semi truck spring suspension parts also keep your suspension system at a certain height and hold extra weight without slipping.
