Global West has engineered an upgraded upper control arm for 1967, 1968, 1969, 1970, 1971, 1972, and 1973 Mustangs; the arm provides additional positive caster by moving the upper ball joint back towards the rear of the car.

This particular kit is used for street and handling applications. (Global West also manufactures a control arm for drag racing / street.)

The new Plus 3 Mustang arms are shipped assembled with billet cross shafts, Del-a-lum bushings and ball joints. The a-arms are black powder coated and the cross shafts are blue zinc (silver). Global West manufactures this product in its own facility here in San Bernardino CA.

Tech Information: Caster

With upgraded suspension and present tire technology, caster plays an important part for proper handling of the car. Caster does the following: provides straight line stability, has a self centering action on the front suspension, improves initial turn in during cornering and also resists pulling (right hand drift) caused by road crown.

The Alignment Adjustment and Limitation:

Caster on 1967-73 Mustangs is adjusted by moving the lower control arm forward via the strut rod. The strut rod is threaded at one end where the rubber bushings reside. By loosening and tightening the jam nuts you can pull the lower arm forward gaining more caster.

This was not an option on 1967-1973 Mustangs. The real limitation on how much caster you can get is mainly based on the rim and tire combination you are planning on running. The larger sizes limit how far you can move the lower arm forward because the tire runs into the lower portion of the front fender when the wheel is turned.

If this occurs, you will have to reduce caster, which is not the best answer. Now with Global West Plus 3 upper arms you will be able to get the caster you need!

Global West Plus 3 upper arms have 3 degrees of positive caster built into them. This will eliminate the need to pull the lower arm so far forward in order to get the desired alignment.

Note: When using Plus 3 arms, there is now a right and left upper control arm. The original control arms (factory or first generation Global West Negative Roll control arms) are universal.
