Our 5.5 kit for the RWD Ford Rangers set the bar years ago as the best performance kit available. The kit uses our 3" lift fabricated race spindles with a massive 1" vertical uniball that replaces the weak upper ball-joint that is prone to fail. This allows for 10" of useable wheel travel. The upper arms are made from 1.50" x.120 wall 4130 chromoly tubing and double shears the uniball. We use Bilstein 5100 series for added control that bolt right in and are valved for this kit. Our coil springs provide 2.5" lift and are heat-treated and stress relieved. Track width is  increased 1.5" per side giving you a wider stance for better stability and added wheel travel. This is why Fiberglass front fenders are highly recommended. We now include our weld-on upper frame gusset reinforcement kit. This kit fits RWD Rangers with coil springs only. For torsion bar trucks use our Ranger Edge 6.0 kits. 1998-2000 models require the larger 2001+ 11.25" OD brake rotors.
