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).

Warranties
The original intent of the air spring was to provide a very smooth ride. It was not designed to provide an adjustable ride height. You can not drive the vehicle at any ride height you select.
All suspension systems are designed to operate at a specific midpoint position, with provisions for suspension travel. The Mustang II suspension is no exception. It has a specific mid-point position which is when the lower control arms are level. The suspension must be in this position to provide full suspension travel and correct geometry action.
In this type of suspension the shock is normally the bottom out device. When the vehicle is lowered the shocks compression and extension limits change and the shocks will bottom out or the ball joints could pinch when it is lowered. The air ride suspension is only designed to lower your vehicle while it is parked. If you attempt to drive a vehicle in the lowered position it could be dangerous and will cause damage to your vehicle. This could result in broken control arms, shocks and ball joints.
