Overview
Detroit Speed Upper Control Arm Kits
Do you know your geometry? Detroit Speed does! DSE upper control arm kits upgrade your classic musclecar's suspension geometry to today's standards of performance. Using computer modeling and on-road testing, DSE has engineered complete and comprehensive kits that include everything you need for the install. All you need to do is follow the instructions and supply the grease. The main features of these robust Detroit Speed upper control arms are the CNC-machined stainless steel cross shafts fitted with their caster tuner bushings--aluminum bushings that adjust caster by moving the upper control arm fore/aft for more or less caster, without adding alignment shims. And without shims, this unique adjustment design for camber control is precise and permanent. The arms are TIG-welded in a fixture for accuracy and repeatability of geometry. The arms are powdercoated gloss black and come assembled with ball joints, and two sets of caster tuner bushings are included. Get your ride armed for consistent, precise performance with Detroit Speed upper control arm kits.
Other features that add to the precision fit and increased strength of these kits are:
* DSE-designed greasable aluminum/Delrin bushings
* CNC-machined bevel stainless steel washers
* Stainless steel Nyloc nuts
* CNC-machined tubes ends
* CNC-machined billet ball joint pockets
