Lock down rear axle alignment, eliminate wheel hop under acceleration, and maintain precise track geometry across aggressive cornering loads with our rugged selection of Auto Trailing Arms. At DIY Customs, we provide high-strength replacement trailing arms, specialized adjustable rear control rods, durable chassis relocation brackets, and high-durometer polyurethane bushings designed for a perfect fit on independent rear suspension (IRS) cars, classic muscle cars, and off-road utility vehicles.
