Heidts Mustang II crossmembers for 1949-54 Chevy passenger cars offer you the choice of Deluxe (welds ground) or Economy (unground welds). The Chevy models have frames and fenders which lend themselves nicely to Mustang front end conversion, without changing the critical geometry. 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. Longer tie rod ends aren't used - ever!
Mounting points of all control arms match the original Ford design. Factory anti-drive built right in. Heidts crossmembers offer you the choice of Deluxe (welds ground) or Economy (unground welds).Mustang II cross members using stock spindles will drop the stock ride height 3-4. Nothing to measure or trim. One-Piece Shock Cups are T. Welded in place and have anti-dive built in. First class, for your car. This is the strongest design available, with twice the weld area.
This will keep your frame from twisting! Main crossmember made from only 2 formed pieces for maximum strength and accurate fit. Crossmember and Spring Towers precut and pre-welded to fit your frame.Lower control arm pivot tubes and gussets are NOT included. Works with both manual or power rack and pinions. For a LARGER selection at a LOWER price, see Speedways collection of mustang II crossmembers.
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 for installation with these crossmembers to fine tune your final ride height up to 2.Note: When using this crossmember with our "power" steering rack, you may also need (2) rack spacers (9101023). These spacers are included with our Mustang II suspension kits. Combine that with improved stopping ability due to numerous brake options and it becomes more a question of Why wouldn't you? The independent suspension will give you a much better ride because there is double the suspension travel. A stock axle will give you maybe 2-1/2 of total travel vs. A Mustang II which will give you about 4-1/2"- 5" of travel. There are multiple spring rates available to accommodate varied applications and the rack and pinion steering is much more responsive than a standard steering box. Drop: This varies and is dependent on application and options. Most kits drop the vehicle by 3-4. Drop spindles and running lower profile tires than stock also adds to the amount of drop that can be achieved. Track Width: You may want to mount custom wheels to your Mustang II conversion and determining proper track width for your application is essential for figuring correct backspacing and overall ride stance. Standard wheel base is 56-1/2" with a 60" version available for trucks.
The various options for brake kits will vary this somewhat and some kits can add roughly 2 to the overall track width. Narrowed arms are available to move the wheel in by 5/8 on each side. See the link below for various track widths with different options. Deluxe style crossmembers come with all welds ground for a smooth finish while Economy style crossmembers feature unground welds.Assembly Notes: Either manual or power steering can be used with these crossmembers. The passenger side mount has a slot that will take the later model power rack. With all Mustang II aftermarket crossmembers, spacers and longer bolts must be used with the later (Fox-body) power rack. Rack mounts are incorporated into the crossmember design and rotate the rack back 20° to get the input shaft lower.
Stock, manual, power racks, or later model Mustang II or T-Bird power racks can be used. The rack is positioned so the bellows will clear most aftermarket full A-Arms. When using crossmembers with our "power" steering rack, you may also need (2) rack spacers (9101023).
The holes for the lower control arms are 1/2' (stock). If you will use tubular lower A-Arms instead of the stock lower arms, the lower pivot holes will have to be drilled out to 5/8'. These crossmembers will work with stock control arms.
If used with stock arms, these will require strut rods and strut mounts for installation. Speedway crossmembers DO NOT include strut rod mounting brackets.
We recommend either our offset or no-strut control arms or the tubular strut rod (91034322). Includes crossmember and shock cups.
