The Lone Star Racing Hi-Clearance Trailing Arms are made of 4130 chromoly so they are stronger and will save over 8 lbs off the weight of the stock trailing arms. These trailing arms are designed to have 2.5" more ground clearance just before the tire. They come with HD rod ends and stainless steel inserts. They are compatible with your stock suspension, as well as our MTS kit. Sold as a pair.
