Description
Upgrade your lifted truck’s suspension with the SuperPro Front Upper Control Arm Set, part number sprTRC6645. Designed for select Dodge Ram 1500 DS and Ram 1500 Classic DS applications, these performance suspension arms feature fixed-offset geometry to help restore front-end alignment and suspension geometry on trucks lifted between 2 and 4 inches over stock.
The SuperPro fixed-offset upper control arms incorporate camber and caster correction into their design, helping reduce the need for time-consuming adjustments and trial-and-error alignment. The corrected geometry is engineered to improve steering feel and accuracy, straight-line stability, turn-in response, and predictable cornering.
Each set features uprated, high-articulation ball joints and SuperPro bushings designed to reduce unwanted control arm movement and deliver dependable performance. Built for both daily driving and off-road use, these upper control arms help improve road manners, on-road handling, and durability on demanding trails.
When paired with the OEM lower control arms, the manufacturer states that the related SuperPro TRC6640 kit delivers -0.5 degrees of camber and +4.0 degrees of caster at a 3-inch lift. These figures are provided for the referenced TRC6640 kit and should not be assumed to be guaranteed alignment results for TRC6645.
Designed and developed in Australia, SuperPro suspension components draw on nearly five decades of suspension engineering experience. This set offers a performance-focused upgrade for compatible lifted Ram trucks.
