What's in the Box

Info

These Speedway Mustang IFS kits for 1964-70 Ford Mustangs 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.  There is no need to widen or otherwise modify the Ford design or use long tie rod ends! Included in these kits are illustrated installation instructions.
  • 1964-1970 Mustang passenger car frames
  • All Speedway crossmembers come in Deluxe versions (welds ground)
  • Constructed of 7-gauge steel
  • 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 included for added strength/support
  • Inner fender panels are available to cover cut-out hole during installation
  • Works with both manual or power rack and pinions
  • Works with tubular control arms only

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

910-34457 Crossmember Installation Instruction Sheet (PDF)

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".  Inner fender panels are available for these crossmembers, (91034450) for 1964-66 and (91034451) for 1967-70 Mustangs.  These crossmembers come with frame boxing plates included for added strength/support.

Note:  Must use rear sump oil pan. Raised engine placement may require a high-rise hood. Cleveland engines will not work. 2" drop spindles are recommended to retain stock ride height.

Note:  This crossmember is to be used with tubular control arms, as there are fit issues with the stamped steel stock style control arms. 

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.)

Item Details

1964-70 Mustang Passenger Car
Complete installation may require you to purchase corresponding a-arms, shocks, springs, brake kit, spindles, and steering rack and pinion

Application

2" dropped spindles required
  • 1964-70 Mustang
  • 1967-68 Cougar

This crossmember is to be used with tubular control arms, as there are fit issues with the stamped steel stock style control arms. Further, dropped spindles must be used (see 910-34304) to maintain stock ride height.

If you are using a power steering rack, you will need to purchase two rack spacers #413-1023.

We carry repair panels to fill the holes left when the original suspension is removed:

  • 910-34450 for 1964-1966 Mustang
  • 910-34451 for 1967-1970 Mustang

Note: Crossmember DOES NOT fit 1963-1965 Falcon.

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.)

This crossmember is to be used with tubular control arms, as there are fit issues with the stamped steel stock style control arms.  Lower control arm pivot tubes and gussets are not included.

This kit was easy to install. The price is right. Why spend all that money to completely rebuild the original front end, steering, brakes, etc.(especially if you want front disc brakes)? Spend a tad more and put in an IFS. The laser cut pieces fit like a glove and the installation instructions are easy to follow. Just think it through and measure twice
Pros:
  • Strong
  • Easy To Install
  • Price
Yes, I recommend this product.

This crossmember will only work on the 64-70 Mustang and Cougar applications. Sorry we do not offer a crossmember for your application. You could possibly use the universal crossmember 413201 or 413202.

Header and spring choice? I intend on installing a 429/460 engine in this unit (a '69), I assume that besides the rear sump oil pan that one would use the Fox body engine swap headers? And spring rates for the coil over kit? Any recommendations?

Installing a Mustang II suspension in a 64-70 Mustang needs to include the use of dropped spindles to keep original ride height. By removing the inner towers you will gain some needed engine space. Headers from the fox body are not a guaranteed fit but would certainly be worth a try. The coilover spring rate with the 460 engine will probably need to be 550 pound if using the 10" springs or 600 pound if using the 8” springs.

Cross member number 91034457 for the 64-70 Mustang will NOT work on the Falcon applications. We apologize for the inconvenience and currently a cross member is not available for the Falcon cars. You may want to check other suppliers for the cross member and keep Speedway in mind for the complete hub to hub kit available in many versions.

Our 1964 -70 mustang crossmember kit is listed for the Mustangs & Cougar 64 - 70. There is no info or indication it will fit a 1968 Torino. A fabricator could compare the different suspension & frame configurations of those years may be able to fit it.

Depending on what engine you are using there are several options. Most options will require welding a fabrication when installing a crossmember like this.

Sorry we have not tried the Mustang II crossmembers with Coyote engines. You would certainly need to fabricate mounts for the engine.
