Spring Rate Chart (Link)

WARNING: 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: These IFS kits will require use of strut rods and brackets for the lower control arms.  These kits will work with our replacement strut rod (91034315) and brackets (91034358).  If using the stock style control arms we suggest using the tubular strut rod number (91034322) for additional clearance and better suspension geometry.

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)


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.
