The Detroit Speed upper control arm kit is a complete and comprehensive package. Detroit Speed has done all the engineering and testing, and supplies all parts needed to complete the installation. All you will need to do is follow the instructions and supply the grease. Our Detroit Speed, Inc. Upper Control Arms are quick and easy to install and align.
The Detroit Speed upper control arm kit is a bolt on enhancement for 1978-88 G-Body platforms. Suspension geometry is improved over stock by increasing camber gain and improving roll camber. Detroit Speed's upper control arms have been computer modeled and the components have undergone finite element analysis.
The control arms have CNC stainless steel cross shafts which incorporate Detroit Speed's Caster Tuner Bushings. These aluminum bushings adjust caster by moving the upper control arm fore/aft for more or less caster without adding alignment shims. This unique caster adjustment design is engineered to be precise and permanent.
The upper control arms also utilize Detroit Speed designed bushings. These greaseable aluminum/Delrin bushings have an increased stiffness over stock. This provides more consistent and precise handling. The bushings also have CNC machined bevel stainless washers and stainless ny-lock nuts.
The upper control arms have CNC machined tube ends for precision fits. The arms are then TIG welded in a fixture for accuracy and repeatability of geometry. The ball joint pocket is CNC machined from steel for increased strength. The arms are powder coated gloss black and come assembled with ball joints. Two sets of Caster Tuner Bushings are included. The Detroit Speed, Inc. upper control arms are ready to bolt on!
