Speedway Motors 91034431-DLX Details

These Speedway Mustang IFS kits for 1934-1935 Chevy passenger cars are natural conversions to improve your vehicles suspension, handling, and overall performance. The Chevy models have frames and fenders which lend themselves nicely to the Mustang front end conversion, without changing the critical geometry. Like our Ford kits, Chevy kits do not bumpsteer at all. Included in these kits are all the special, hard-to-make brackets and mounts you will need to complete the installation, plus illustrated installation instructions.

  • Mounting points of all control arms match the original Ford design
  • Factory anti-drive built right in
  • 1934-1935 Chevy Standard car frames
  • All Speedway crossmembers come in Deluxe versions (welds ground)
  • Constructed of 7-gauge steel
  • Mustang II cross members using stock spindles will drop the stock ride height 3-4”
  • One-Piece Shock Cups are T.I.G. welded in place and have anti-dive built in.
  • Vertical Inner Uprights. This is the strongest design available, with twice the weld area. This will keep your frame from twisting!
  • Crossmember and Spring Towers precut and pre-welded to fit your frame
  • Lower control arm pivot tubes and gussets are NOT included
  • Works with manual rack and pinion ONLY

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

Note: Radiator tabs included. 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".

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.
