Spring Rate Chart (Link)

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 IFS kits to fine tune your final ride height up to 2".

Note:  If using these kits with Speedway or Heidts crossmembers for 1948-1956 Ford Pickups, 1955-1959 Chevy Pickups, or universal crossmembers for 27-1/2" - 33-1/2" frame widths, you will be required to purchase 2" Inner Tie Rod Extensions (91034345) or (91034346).

Item Details

'Must include Mustang II crossmember for complete installation (sold separately)

Notes

Why go with tubular control arms? The most obvious reason is the looks. Tubular control arms and strut rods give your hot rod a much cleaner and hi-tech appearance than the stock type do. Also, when using the strutless style, you gain more clearance because you no longer have the strut rod or its mount in the way of headers, etc. Another bonus is that the tubular control arms are available in 5/8" narrower than stock, which helps tuck the wheels up under the fenders without having to buy expensive special offset wheel. When using 5/8" narrower control arms, 5/8" must be removed from each inner tie rod end.

Note: To offer our customers a better range of spring rates, the springs included in this kit are now black in color, please note that they are no longer chrome plated.

Note: Applications where the vehicle has fenders that mount directly on top of the frame, the fenders will require extensive modification to allow clearance for the upper cross member section.

Note: These kits require the purchase of a Mustang II crossmember (sold separately).  Many of our Speedway and Heidts brand crossmembers will work with Manual Rack and Pinion Steering ONLY.  When purchasing our crossmembers, be sure to look for their correspondence with power racks if selecting a power rack with our Mustang II IFS kits.  With all Mustang II aftermarket crossmembers, spacers and longer bolts must be used with the later (Fox-body) power rack (spacers included).

Finding the right control arms means finding the correct track width: Our Mustang II kits feature 11" rotors.  Track width, which is hub face to hub face where the wheels bolt on, will be 57.5". Wheel and tire combination and customer preference determine whether to use the
standard control arms or the 5/8" narrower. The narrower control arms reduce the track with by a total of 1.25".  See the link below for
various track widths with different options.

Good Quality Product

May 18, 2016
Used the kit on a 1940 Ford pickup build and it worked well. Even though the frame was on a rack and the outside to outside frame measurement was to factory specs, had to add shims on the inner frame rail boxing plates to get the crossmember to fit properly. Probably a fault with the frame, not the product but be prepared to make "adjustments" when working on this old stuff. Good order response and delivery time.

First time installer

May 07, 2016
Installed this product on a 1950 Chevy Coupe(my first time of installing one) and the instructions are far too vague for a newbie. Once installed (after asking others alot of questions) I noticed it actually RAISED the front of my car, the lower control arms were not parallel to the ground. Called tech and was told the stock configuration springs are "trim to fit", and the ball joint boots don't fit well.The spring issue needs to be addressed in the instructions. Now having said that, I would still recommend this product simply because of the cost to quality ratio.It seems to be a very good kit for the money, the car drives very good after installation, and tech support is more than happy to help with any inquiries.
Pros:
  • Good Technical Assistance
  • Good Product Quality
Cons:
  • Instructions Are Vague
  • Springs Are Trim To Fit
  • Needs Photos
Yes, I recommend this product.

Product needs some Instructions

January 13, 2015
All items were packaged and in good condition, the control arms are quite beefy, the rubber cover over the ball joints just float and should be able to be slipped over a notch to be secured instead of just floating. Also there needs to be some sort of assembly info, (photos, instructions etc.) as if this is a newby trying to get this together they might have trouble, other tha that it is a good kit.
Pros:
  • beefy
Cons:
  • no assemble instructions
Yes, I recommend this product.

Great item...this is my 2nd one but rubb

September 08, 2013
This is the 2nd MSll kit that I have used and they work great mechanically, however.... an improvement that I recommend is the rubber bushings that are located at the ball joints do not fit as they should. Because they are flat where they meet the ball joint, they don't seat but just 'compress and "float" at that area......they don't stay centered and dirt gets into the ball joint. I've tried adding a picture but cannot?
Pros:
  • good mechanically sound
Cons:
  • ball joint bushings....see comments
Yes, I recommend this product.

Yes both kits can be used on your 1947 Ford pickup. You will first need to install a crossmember such as 91034430. For your application you will also need rack extensions 91034345. The difference between the two kits you have indicated is that this kit uses tubular control arms and stock height spindles where as 91034101 uses stock (stamped steel) control arms and 2" dropped spindles. Typically stock height spindles work well with pickups. The installation of this suspension will drop the truck quite a bit already.

You would need a crossmember to mount the Mustang II suspension to. We offer two universal corssmembers that may be able to be used. 413201 provides 56 1/2" hub to hub width and is for frame widths of 24" to 30". 413202 provides 60" hub to hub and is for 27 1/2" to 33 1/2" frame widths. Check your frame width and desired hub to hub width to determine which crossmember is better suited to your car.

Answers

The IFS kit could be used on your 62 F100 but we do not have a cross member that needs to be added to the kit for your pickup. Your frame is wider and possibly could be modified to use a universal cross member such as 413202. you will need to measure outside to outside of the frame where the cross member will be installed to verify the cross member will suffice the needs.

Answers

May 29, 2014

This kit will work on your 56 as long as you install the appropriate cross member to mount this suspension onto. I have two universal crossmember options that may be of help in that area. They are part numbers 413201 and 413202. Measure you outside frame width and front track width (or hub to hub width) in order to pick the correct crossmember. Sorry 11" rotors are the largest I offer for this kit and I do not offer them in a drilled or slotted version.

I am a little unsure of what item you are interested in knowing the steel specification for. If you are referring to the material that the cross members are made of it is a standard low carbon steel. Sorry I do not have an exact specification for the steel.

I am installing the Mustang II front suspension on my 1950 Studebaker and had a question on the lower control arm. There is a bracket with a hole in it on the lower control arm I guess this is for a torsion bar connection? Is this bracket suppose to be facing toward the back of the truck or or the front. It seems that it would interfere with the steering when faced to the front, but if I face it to the rear the spindle would not be in line top to bottom. Thanks, Brian

We apologize for the confusion but the bracket goes towards the front and is a sway bar bracket if you decide to put one on. Currently we do not have a sway bar kit available.

Sorry this kit does not work well with a Model A that has front fenders. We no longer carry the correct crossmember for the Model A due to the fact that most customers were not happy with the appearance of the fenders once there was enough clearance cut out of them.

Measure between the front frame rails, order a cross member that is within those dimensions from Speedway (or Welder Series) and follow directions. Get item 91034202 from Speedway, follow directions.
September 05, 2013
Jason
Speedway Motors cannot guarantee that the Street Beast all used the same front end but from customers we have worked with the Mustang II was used. The upper holes for the control arms should be 5” on center and slotted for alignment purposes. Mount holes for a front steer rack and pinion will also be slotted to accommodate 15 ½” or 16” mount centers. If those measurements appear the same it is likely to be a Mustang II front suspension.

Speedway offers cross member number 91034457 to work with your 69 Mustang. It is a weld in version and a bolt in version is not available currently. It will require welding experience plus some mechanical back ground for set up. It requires the use of a tubular hub to hub kit for necessary clearance and you may also be interested in the inner fender panels number 91034451 to fill in where your original shock towers installed. To maintain near stock ride height dropped spindles must also be used.

We apologize for the inconvenience but currently Speedway does not offer a cross member for the IFS kits. If a cross member is obtained from Heidt’s or Chassis Engineering you could use the kit we offer but it will not accept running the full fenders without extensive modification to clear the upper spring hat that welds to the top of the frame. We suggest Heidt’s Super Ride kit be used on the full fendered Model A’s.
