1974-81 Camaro Drag Race kit with tubular uppers and Low friction Del-a-lum bushings Part # ETPK-7481

Specifically designed for drag racing with the 1974, 1975, 1976, 1977, 1978, 1979, 1980, and 1981 Camaro, Global West Suspension sells tubular upper control arms with low friction bushings that allow the front end to respond quickly. The kit also includes lower ball joints and low friction Del-a-lum bushings.

Upper Arms

Reduced Bump Steer

With this set, bump steer is reduced through new geometry induced by the control arm. Bump steer is a condition that occurs as the front of the vehicle raises, the wheels turn on their own without driver input. This causes tire scrub and front end wander.

Geometry Change

One of the biggest problems most production cars have is not enough caster. Caster provides straight-line stability and reduces wander at high speeds. It is part of the front end self-aligning force. For this reason, caster is essential on drag cars. Unfortunately, there is never enough caster available using stock front-end components. Too many alignment shims are needed and possible camber problems can occur. TLC upper control arms are built with additional 6 degrees positive caster and setting camber is never a problem. Also the arms are made out of chromoly which removes 8 pounds off the front end.

Control Arm Shafts

All TLC upper control arms use billet aluminum cross-shafts. Steel sleeves are pressed in on each side of the shaft for protection. The sleeves isolate the aluminum shaft from alignment shims, frame bolts and nuts. This allows proper torque to be maintained on the cross-shaft. Without steel sleeves, alignment shims and upper shaft bolts would rest against the aluminum shaft and eventually work loose. Once the bolt works loose, alignment shims would fall out causing loose alignment.

Control Arm Bushings

All drag series A-arms use a low friction bushing that allows the control arm to literally drop when they are installed. The beauty of design is that not only is there reduced friction, but there is zero deflection and no fore and aft movement. TLCs use Delrin type bushings machined specifically for our shafts and housings. Delrin, which is patented, is a hard plastic and can handle extreme loads associated with suspension components. It is long lasting and very durable. Grease fittings are installed in the control arms for lubricating the bushings. Synthetic grease is recommended.

Bump Stops

Bump stops are installed on the upper control arms to stop ball joint over travel. This protects the upper ball joint from damage. Sometimes, if the front end travel needs to be limited, the bump stop may be removed and a limiter may be added in its place. Always check the suspension travel. Make sure the bump stop contacts the frame before the shock runs out of travel. Modifications to the suspension can change the distance required.

We recommended using our Drag Race Bump Stop Limiter part# TLC-1100

Lower Arm Bushings

Del-a-lum Bushings

Del-A-Lum works like a bearing but it’s a bushing! We designed these bushings in 1981 and they have surpassed the test of time. They rarely wear out and are in almost every tubular arm kit that Global West produces.

Global West Del-a-lum bushings only allow straight up and down movement eliminating fore and aft deflection. They 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.

Del-A-Lum bushings are a direct replacement for rubber or polyurethane control arm bushings and are perfect for street or race applications. This unique design provides smooth performance without squeaks or bind. Designed to last over 100,000 miles. Whether on the street or on the track, Del-A-Lum bushings will give you optimum performance and control.

Note: You must check your lower control arm frame bolts to see if they use a 1/2 inch bolt or a 9/16 bolt. 1970 - 73 frames all had 1/2 inch bolts and 1974 - 81 had 9/16 bolts. It is very possible that you could have a 74 frame in a 73 car. Sometime during the latter of 1973, 74 frames where being installed.
