Global West Suspension manufactures quality tubular front upper control arms for 1967, 1968, and 1969 Firebird suspension upgrades. The upper arms are also outfitted with Global West billet steel upper control arm shafts, polyurethane bump stops, and upper ball joints.
The Global West Advantage:
Since Global West introduced the arms in the early 1990s, other manufactures have tried to replicate its design. However, major differences in quality separate the original from the imitations.
For instance, our the control arm has a different geometric shape and possesses a unique camber curve associated with caster. This combination reduces the factory bump steer and provides dramatic handling improvements. New alignment specifications are included for street applications but also drag racing and auto-cross.
The control arms are also outfitted with the best bushing on the market, Global West Del-a-lum bushings. The company designed this bushing in the early 1980s for street and road race applications. Since then, the NHRA has approved them for stock classes, and they are also used in circle track. Only Del-a-lum bushings from Global West Suspension have a limited life time warranty.
Benefits and Features:

TUBULAR UPPER CONTROL ARM KIT #CTA-79A, CTA-79AP
1967-1969 CAMARO/FIREBIRD AND 68-74 NOVA
Kit CTA-79A, AP is a fully assembled control arm complete with bushings, cross shafts, upper ball joints, and snubbers. Installation is simple.
1. Lift the front of the vehicle up and support the frame with jack stands.
2. Remove the front tires and place a floor jack under the lower control arm out by the ball joint. Using the floor jack lift the lower arm up until the upper control arm is off the upper frame bump stop. (Place an additional floor jack under the control arm for safety).
3. Remove the upper ball joint nut and separate the ball joint from the spindle by using a pickle fork.
4. Remove the 2 bolts supporting the upper control arm cross shaft. (Remove the alignment shims located next to the shaft and remember what position they came from. Note: Don't worry about it if you forget. The alignment shop is going to adjust them anyway).
5. Remove the upper control arm by sliding them off the frame studs. (If the exhaust is in the way press the studs out. DO NOT PUT A SOCKET ON THEM AND TURN THEM OUT. THE BOLTS ARE KNURLED. SPINNING THEM OUT WILL DAMAGE THEM).
6. Install your new upper arm. There is a right and left. The shortest tube on the upper arm goes towards the rear of the car.
7. If you had to remove one or both of the upper frame bolts, simply take a drift and tap them back into the frame. Make sure the new arm is in position first.
8. Place the alignment shims back on the bolts and tighten down the upper shaft to the frame. (The shims go between the frame and the upper shaft).
9. Slip the upper ball joint through the spindle and tighten the ball joint nut. Torque to 60 foot pounds. Lubricate ball joint and install the cotter pin.
10. Remove the safety floor stand and lower the floor jack. Repeat the same procedure for the other side. After completion you must get the car aligned.
Street alignment settings
Passenger side --- Caster 5 1/2 degree's positive --- Camber 0 to 1/2 degree's negative
Driver side --- Caster 5 degree's positive ---- Camber 0 to 1/2 degree's negative
Set toe --- toe-in (3/32 total)
Road Racing initial settings
Passenger side specifications -- Caster 6 degree's positive , Camber 1 1/4 to 2 degree's negative
Driver side ---- Caster 6 degree's positive, Camber 1 1/4 to 2 degree's negative
Set toe to toe-in (3/32 total) long course, set toe to toe-out short course 1/16 out per side. Set toe by pushing out on the front of the tires. Notice the deflection in the steering system. There should be very little. The toe should be measured at this point.
Drag Racing alignment specifications
Passenger side --- Caster 6 degree’s positive ---- special note for camber - see below
Driver side --- Caster 6 degree's positive
Raise the car with a floor jack located at the cross member 3/4 of an inch. Set the camber to zero both sides.
Set toe to toe-in (1/32 total). Set toe by pushing out on the front of the tires. Notice the deflection in the steering system. There should be very little. The toe should measure 1/32 in (total) at this point.
For your information, Del-a-lum bushings were designed back in the early 80's by Global West Suspension. They have been featured in Engineering digest, Mechanics Illustrated, and several automotive magazine in the United States over the past 30 years. Del-a-lum bushings have a lifetime warranty to the original purchaser and they are available for more than 80 different applications including stock control arms. It is no surprise that Del-a-lum bushings have been copied by many in the last few years. If you copy something why would not copy the best.
