You dont have to look any farther for tubular control arms for your Mustang II IFS-equipped hot rod. Our Mustang II control arms are made from full .120 wall, 1" diameter tubing, fixture welded and feature screw-in ball joints and no-squeak rubber bushings. These new generation, no-strut style arms eliminate the strut rod found on stock-style Mustang II IFS systems. The improved, triangulated design provides stability and strength within the arm itself, so you can get rid of that ugly strut rod.
Will work with nearly any stock or aftermarket Mustang II front crossmember (welding is required on most applications). For use with Ridetech/Air Ride front air bag air springs. These control arms are 5/8" narrower than stock, which means that they will reduce front track width by 5/8" per side (or 1-1/4" overall) when compared to a stock width control arm. This helps tuck the wheels up under the fenders without having to buy expensive special offset wheels. When using 5/8" narrower control arms, 5/8" must be removed from each inner tie rod end.

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.
