Drag Race Dedicated Suspension Systems
Lightweight tubular upper control arms are fully assembled with billet aluminum cross shafts, special Delrin bushings, ball joints, and shortened bump stops. The upper arms are made out of 4130 chrome-moly to reduce front-end weight.
Geometry Change - Nothing But Positive
One of the biggest problems most production cars have is not enough caster. Caster provides staight-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 positive caster and steeing camber is never a problem.

Control Arms 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.
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.
Bushings
TLC control arms use Delrin type bushings machined specifically for Global West's shafts and housings. Delrin 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.
TLC Lower Control Arms
TLC lower arms are similar to the G-Plus lower control arms. The TLC arms have no sway-bar attachment points or additional plates in order to lighten the arms. The arm is considered a load carrier and is ''beefed up'' to handle wheel stands and extreme loads. Weight savings is minimal using the lower arm because of the tubing wall thickness required.
