    These are Heidts Mustang II crossmembers for 1947-54 Chevy Pickups. The Chevy models have frames and fenders which lend themselves nicely to Mustang front end conversion, without changing the critical geometry. Chevy IFS kits also come complete with the hard-to-make special brackets, such as radiator perch on certian models, to quickly and easily complete the installation. Like Heidts Ford kits, Chevy kits do not bumpsteer at all. Chevy kits come with a step-by-step, fully-illustrated instruction booklet to ensure that your installation goes as easily as it should! Correct design results in correct camber action – and no bumpsteer.

    Choose from the crossmembers below and add to an IFS kit to get a "hub to hub" front suspension.

    Note: Additional items may be needed to complete installation. You may want to include our Mustang II ride height adjusters (91034444) for installation with these crossmembers to fine tune your final ride height up to 2". Frame boxing plates (91054428) are also available for these crossmembers for added strength and support.

    Note: This crossmember is designed to be used with a manual rack only. A "power"rack-and-pinion interferes with the radiator and/or the radiator support brackets.
