What's in the Box

Info

These Speedway Mustang IFS kits for 1953-1956 Ford F-100s are natural conversions to improve your vehicles suspension, handling, and overall performance.  They retain all the factory dimensions and locations, so you get all the benefit of factory Ford engineering in your front end.  Included in these kits are illustrated installation instructions.
  • 1953-1956 Ford F-100 pickup 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!
  • Lower control arm pivot tubes and gussets are NOT included
  • Frame Front Boxing Plates are available for added strength/support (91054425)
  • Works with both manual or power rack and pinions
  • Requires use of 2" inner tie rod extensions

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 installationYou 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 (91054425) are also available for these crossmembers for added strength and support. You must use 2" inner tie rod extensions for proper steering geometry with these crossmembers.

Note:  This crossmember requires the use of rack extensions (91034345) for the manual or the power rack. Further, rack spacers are also required when a power rack is used.  Please consider item #910-34346 or 910-1023.

(requires use of inner tie rod extensions)
Complete installation may require you to purchase corresponding a-arms, shocks, springs, brake kit, spindles, and steering rack and pinion

Notes

Overall Benefit:  In a word, "handling". While installing a Mustang II can look like a lot of work, in reality, the improved handling and ride quality are worth the effort. 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.

 Mustang II Track Width Options (PDF)

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). (These spacers are included with our Mustang II suspension kits.)

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″.  Lower control arm pivot tubes and gussets are not included.

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).

Great product!

June 21, 2010
I am restoring a 61 Ford F-100 and it fit perfectly in the frame. All the welds are nicely done and look like a machine did them. The only thing I would say that detracts from it, and it's not a big deal at all, there was a few surface spots of rust, since it's bare metal. But it will sand off easily. Great product!
Pros:
  • Perfect Fit
  • Well built
  • very strong
Yes, I recommend this product.

We have customers with a big block 460 in the 53-56 Ford pickups and occasionally even with a blower. If you try the diesel and with the extra plumbing required may well be borderline. If you decide to go this route we would suggest the standard springs and shocks (not coilovers) and the heaviest spring rate we have available is 425 which equates to a total front end weight of 1800 pounds.

If the basic 55 Ford pickup with 350 Chevy engine then a 350 spring rate would cover 1500 pounds up front with the standard springs. If the frame has some upgrades and some other options a 375 rate would be the most likely. If you were to have air conditioning the 375 would be the base rate.

Part number 91034425 is for the 53-56 Ford pickups which have a different dimensioned frame than the 48-52 which would use our Mustang II cross member number 91034430. Either kit requires the use of inner tie rod extensions to properly align the pivot in the rack to the lower control arm pivot point.

From the frame notch in the cross member number 91034425 to the top of the cross member under the engine is approximately 4" and the cross member is 2" tall. So from the bottom of the frame to the bottom of the cross member is 6".
