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).
