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 kit provides alignment help along with performance.
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.
What is Caster?
Cars back in the 1960’s did not utilize much caster, probably due to the tires of that time. Now, with upgraded suspension and present tire technology, caster plays an important part of the drivability 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 Global West Advantage: Modifying Caster
Prior to the Global West Plus 3 control arm, caster was increased by one of two ways:
- By shimming either by installing or removing shims between the shock tower and the upper control arm shaft: Shims on the front bolt in the upper control arm add caster and camber. Shims removed from the upper control arm rear bolt, also increases caster and reduces camber. In many cases, it is hard to get enough caster and still have adequate camber.
- Using the strut rod to get caster: Unfortunately, the strut rod on 1967-73 Mustangs is non-adjustable. Global West does offer adjustable strut rods (part #ASR-5, ASR-6, ASR-13) that allow caster to be adjusted simply by turning the hex adjuster. The hex adjuster will shorten or lengthen the rod thereby setting caster.
Tech Tip: Strut Rods
Strut rods are a great choice for getting caster; however, the suspension is still somewhat limited.
Here is why: As the strut rod is shortened, which increases caster, the tire is pulled forward closing the distance between the tire and the fender. Depending on the tire’s size, the tire could hit the front fender when the wheel is turned. The optimum choice is to use the Plus 3 upper control arm with the adjustable strut rod. This way, you get optimum caster and no tire rubbing issues with the front lower fender lip.
