Ford Ranger Torsion Bar & Rear Spring Identification Guide:
This guide helps you identify Ford Ranger torsion bars and rear spring part numbers from 1983–2011 using vehicle certification labels, stamped codes, and torsion bar diameters. Learn how to read front torsion bar codes (RH/LH), rear spring codes, and sticker or stamping information to ensure the correct parts for your Ranger’s suspension setup.
Whether you’re performing maintenance, swapping torsion bars, or upgrading your suspension, understanding these codes will help you get the right fit and maintain proper ride height and handling. Detailed charts and photos illustrate each code for easy identification.
