Product Overview: 1964-72 A-Body Drag Racing / Street Drag Upper Control Arms

TLC Upper Control Arms for 1964-1972 A-Body #TLC-42 (For Chevelle, GTO, Cutlass, Buick Skylark, Lemans, Buick GS, 442, EL Camino, Monte Carlo)



TLC Upper Control Arm Link #TLC-42

Product Information:

Lightweight tubular upper control arms are now available from Global West for A-body cars such as Chevelle, GTO, Cutlass, Lemans, Skylark, and 442 (1964, 1965, 1966, 1967, 1968, 1969, 1970, 1971, and 1972 models.)

The control arms are fully assembled with billet aluminum cross shafts, special bushings, and shortened bump stops. They are made out of 4130 chrome-molly and shave 8 pounds off the front end over stock control arms.

Part #TLC-42 includes tubular powder coated black upper tubular arms, upper ball joints, control arm bump stops, Aluminum billet cross shafts, bushings and related hardware. They are shipped fully assembled.

The Global West Advantage:

Note: Plus TLC upper arms are built with 5 1/2 degrees of positive caster into the arm. The stock arm usually tops out at 3 degrees with full shim packs.


• 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 speed. 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 positive caster and setting camber is never a problem.



• 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.



• TLC Upper and Lower Control Arm Bushings: TLCs use Special bushings machined specifically for our shafts and housings. The bushing material, 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 over travel. 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 (part number TLC-1100). 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.
