Firebird Drag Racing Track-Pro Kit 1970-81 #TPK-7081H


Front Control Arms, Bushings and Shafts
Firebird Drag Racing Track-Pro Kit 1970-81 #TPK-7081H
Track-Pro Kits for Drag Racing: Specifically designed for drag racing, Global West Suspension manufactures tubular upper and lower control arms (with low friction bushing) that allow the front end to respond quickly. This package is made for the Firebird--model years 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980 and 1981. The Global West Advantage:
  • Upper Control Arms
  • The upper arms will provide superior geometry, more caster, low friction upper bushings and weight savings. The lower arms provide strength and low friction bushings. This combination will allow the front end to snap up rapidly and due to the design, it will not deflect. The front end will hold an alignment and be stable. New alignment specifications are included in the kit.
  • Lower Control Arms
  • The lower control arms are designed to support a coilover shock and spring combination. This area must support the cars weight and handle wheel stands. The arm will accept several types of mounted shocks such as QA-1, AFCO and others. The shock bolts on top of the lower control arm, not from underneath. The lower arm bushings are made from a low friction plastic. When bolted on to the car, the arm should fall to the ground. Even though the arm moves freely, there is still no deflection fore or aft. This is a great improvement over stock or polyurethane bushings. Straight-line stability is improved automatically.
Tech Tip--Caster: The upper control arms also have built in more positive caster. These particular units have 6 degrees built in. Caster provides straight-line stability. The 1970-1981 Firebird never had enough positive caster available using the stock components. Even if you used offset upper control arm shafts in your stock arm, the best you may get is an average 3- 4 degrees positive. Remember it’s not just getting enough caster, the trick is also getting proper camber at the same time. Did you know that the factory alignment specifications for Firebird from 1970-81 had similar specifications calling out preferred caster at negative 1 degree to 1 degree positive, camber at negative 3/4 degree to 3/4 positive, and toe-in 1/16 to 5/16 in? We come a long way knowing what is needed to make these cars work. The factory specifications are not it. Weight Considerations: Let’s talk about weight. The lower arms are a trade off from stock. We are more concerned with safety then weight. The lower arm needs to withstand a tremendous load. The upper arms are considered followers and are made out of 4130. They do not hold the car up. The cross shafts are made out of aluminum. You will save 8 pounds over the stock units. All of the savings will be in the upper arms. Note: A trick when aligning a drag car is to lift the front end up 3/4 to 1 inch when setting the alignment.
