Welcome to Matt's Classic Bowties

The latest kit from Global West is CTA-71AP Tubular upper control arms for 70-81 Camaro / Firebird applications. It is not just another tubular arm. CTA-71 is built with 1-1/4 inch diameter roll cage tubing, a .187 wall cross brace to reduce flex and maintain control arm strength, and straps located at the bushing housing increasing the control arm strength.

Features:

1. Increased Caster with 5-1/2 degrees of positive caster built into the control arm, straight line stability and corner entry is dramatically improved.
2. Camber curve is improved for high speed maneuvering.
3. Special bump stop mounted on the cross brace provides full drop protection for the ball joints.
4. Stock upper ball joints are used.
5. Built cross shafts are standard with all assembled control arms.

6. Comes standard with upper and lower polyureathane bushings.

7. Control arms are Tig and Mig welded.

8. CNC machined components assure proper jig fitment.

9. Control arms are powder coated black.

10. Special billet shafts are Gold Zinc.

11. No modifications are required. They are designed for direct replacement

Del-A-Lum works like a bearing but it’s a bushing! Del-A-Lum bushings are a direct replacement for rubber or polyurethane control arm bushings. They are perfect for street or race applications. Del-A-Lum bushings feature inner and outer thrust washers, inner rotating sleeve and lube fittings. This unique design provides smooth performance without squeaks or bind. Designed to last over 100,000 miles. Del-A-Lum bushings on the street or the track will give you optimum performance and control.

Note: 1973 Camaro/Firebird Sometime during mid 1973, the factory changed to 1974 subframes. The geometry for both subframes is the same. The lower control arm on 1974 frames use 9/16 bolts rather than 1/2-inch on 1973 frames. The upper control arms on 1974 models have two different size bushings;1973 upper arms use the same size bushing front and rear. Therefore, you must check your components before ordering parts. If you have a 1974 vehicle you will not have these concerns.

Offset upper control arm shafts: All shafts are made out of billet steel and are supplied with hardware for the shaft, but not for the frame.

Why use offsets?

Offset upper shafts are used for several reasons

• Repair alignment because of frame damage or frame sag.

• Repair alignment do to ride height change

• Fine tune alignment for racing or performance applications

For most conditions offset shafts are used for frame issues. They generally give you about 1-1/4 degrees of addition adjustment. However for us in the performance world, they are perfect for getting the best possible alignment using stock suspension. One of the keys to better tire life and performance on these older muscle cars is to increase caster and induce some static negative camber. These older cars roll positive which means as the tire goes up into the fender, the tire tilts out of the fender at the top and increases outside tire wear. Therefore by changing the static factory alignment settings from 1/2 a degree positive camber to a 1/2 of a degree static negative camber, dynamically you will reduce outside tire wear. Increasing the caster will also give you better tire life because of the camber change do to the combination of the spindle inclination angle and increased positive caster.

Note: Caster is an indirect wearing condition where camber is a direct wearing condition.

So increasing caster is going to help straight line stability, corner entry, and tire life.

All shafts are made out of billet steel and are supplied with hardware for the shaft, but not for the frame. Standard non-offset shafts are highly recommended if you are using performance Del-A-Lum or polyurethane bushings. The shafts are made to accomidate 5/8 fine threaded locking nuts rather than a factory shaft that uses a 3/8 bolt holding the bushing in place. We have found that using bolt type upper control shafts and performance bushings tend to back the bolt off over time. If you are switching over to Del-A-Lum bushings, nut-type control arm shafts are required. Bolt type upper shafts are commonly found from the early 1970s and older. Shafts carry a limited lifetime warranty. Excludes 1980-84 Cadillacs
