Heidts Mustang II Crossmembers

Make your IFS stock upgrade a natural conversion with Heidts Mustang II crossmember kits. They are precut and pre-fitted, so you’ll have no measuring, no grinding, no trimming, and no mistakes! Heidts crossmember kits are ready to install when you are. Main crossmembers are constructed from only two formed pieces for maximum strength with an accurate fit and feature the strong design of vertical inner uprights offering twice the weld area to keep your frame from twisting. Crossmembers and spring towers with built-in anti-dive are pre-welded to fit your frame and one-piece shock cups are TIG-welded in place. Kit components may vary by application, but most include all of the special, hard-to-make brackets and mounts that you need to complete the install. Heidts kits retain the original suspension to give you the correct design, correct camber action, and no bump steer! Everything is pretty much done but the installation–that, you’ll have to do yourself! But never fear–Heidts Mustang II crossmembers include a step-by-step, fully-illustrated instruction book to walk you through your install.
