QA1 Tubular Upper Control Arms A/B/E

These QA1 Tubular Upper Control Arms are my favorite fixed tubular upper arm for Mopars. In most cases, they allow up to 4.5 degrees of positive caster, and they’re available for Early A, A, B and E bodies.

Why upgrade to tubular upper control arms

Factory upper arms limit how much caster you can dial in. Yet modern radial tires and quick steering boxes work best with more positive caster. More caster improves straight-line stability and steering return. It also adds helpful camber as you turn, so the outside tire keeps more rubber on the road.

In addition, these arms are built tough. They feature excellent reinforcement in the ball joint area and excellent welds. They’re made from DOM steel tubing with a black powder coat finish.

Installation and alignment

After installation, get a full alignment and take advantage of the extra caster. Because the arms already give you the caster, you won’t need offset upper control arm bushings. Also, check your ball joint style and size before ordering, especially on cars converted from drum to disc brakes.

Why fixed arms instead of adjustable ones? Fixed arms have fewer parts to loosen or wear, so they stay put once the car is aligned. Also, the alignment shop still sets camber and caster with the factory cam bolts. As a result, you get the extra caster without the extra maintenance.
