Unlike weld-on long arm brackets, these are 100% bolt-on — no frame cutting or welding required. The brackets bolt to the JK rear frame using eight 1\/2-13x1.5\" 120M PSI case hardened hex bolts torqued to 110–120 ft-lbs, securing to interior brackets that have preinstalled PEM fasteners. The PEM fasteners capture and hold the bolts in position during installation — eliminating the frustration of trying to hold bolts inside the frame while torquing from outside. This interior bracket clamping method provides superior clamping force compared to designs that clamp the entire frame rail. Both upper and lower rear long arm mounting positions are included in this bracket set, enabling a true 4 long arm rear suspension configuration. Both mounting locations use a 9\/16\" bolt with a 2-5\/8\" inside diameter. Designed in 3D Solidworks for a precision fit to the JK rear frame.
