Detroit Speed Tubular Upper Control Arms (1978-1988 GM G-Body / 1982-2003 S10 2WD) - 030107DS
Sharpen the front suspension response of your GM G-Body or S10 platform with the Detroit Speed 030107DS Tubular Upper Control Arm Kit. Designed as a bolt-on performance upgrade for 1978-1988 GM G-Body and 1982-2003 S10 2WD applications, these upper control arms improve factory suspension geometry by increasing camber gain and improving roll camber. Instead of simply replacing the original stamped control arms with tubular pieces, Detroit Speed engineered the complete assembly around more performance-focused geometry for more consistent and precise handling.
Detroit Speed developed the 030107DS using computer modeling and finite element analysis. The upper control arms feature CNC-machined tube ends for precise component fit and are TIG welded in a fixture to maintain accurate and repeatable geometry. Each ball joint pocket is CNC machined from billet for increased strength, while a durable gloss black powder-coated finish protects the completed assemblies and gives the suspension a clean performance appearance.
A major advantage of the 030107DS is Detroit Speed's Caster Tuner Bushing system. CNC-machined stainless steel cross shafts incorporate aluminum Caster Tuner Bushings that allow caster to be adjusted by moving the upper control arm fore or aft. This provides a precise and permanent method of adding or reducing caster without adding alignment shims specifically for the caster adjustment. Two sets of Caster Tuner Bushings are included with the kit.
The control arms also use greaseable aluminum/Delrin bushings with increased stiffness compared with stock-style bushings. Reducing unwanted bushing compliance helps the suspension maintain more consistent geometry under load, improving steering precision and overall handling response. CNC-machined beveled stainless steel washers and stainless steel Nylock nuts complete the bushing assemblies.
Detroit Speed supplies the 030107DS as a comprehensive package with the control arms assembled with ball joints and ready for bolt-on installation. Detroit Speed states that installation should take less than one day and should be followed by a professional front-end alignment. The manufacturer installation instructions specify 45 feet-pounds for the upper control arm-to-frame fasteners and 60 feet-pounds for the upper ball joint-to-spindle connection. Chassis grease is required during installation.

FAQs
How do the Detroit Speed 030107DS Upper Control Arms improve handling?
Detroit Speed revised the upper control arm geometry to increase camber gain and improve roll camber compared with the stock suspension. The greaseable aluminum/Delrin bushings also reduce unwanted compliance, helping maintain more consistent suspension geometry and providing more precise front-end response.
How do the Detroit Speed Caster Tuner Bushings work?
The aluminum Caster Tuner Bushings reposition the upper control arm fore or aft to increase or decrease caster without requiring additional alignment shims specifically for the caster adjustment. Two sets are included, and a professional front-end alignment should be performed after installation.
