A-body Drag Race Econo Track-Pro Kit Part #ETPK-6466

Specifically designed for drag racing, Global West offers tubular upper and lower control arms with low friction bushings that allow the front end to respond quickly. This kit is designed for the Chevelle, El Camino, Malibu, and Monte Carlo--model years 1964, 1965, and 1966.

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. The combination will allow the front end to snap up rapidly and do to the design will also not deflect. The front end will hold an alignment and be stable.

Global West Advantage: Upper Control Arms

The upper control arms also have built in more positive caster. These particular units have 6 degrees built in. Caster, as you probably already know, provides straight-line stability. A-bodies from 1964-1972 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 4 degrees positive, but average is closer to 3 degrees positive. If your class permits, the TLC-upper control arm is definitely the way to go.

Econo kits also include: Del-a-Lum bushings and ball joints for the lower control arm. The Del-a-lum bushings only allow straight up and down movement eliminating fore and aft deflection.

These are superior over stock and polyurethane bushings. Del-a-lum bushings also will not distort / cold flow over time which will maintain your alignment. This combination is equal to that of using the tubular lower arm but without the strength of the tubes.
