Upper Control Arms (UCA631)
Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR's single-adjustable tubular control arms for 2015-2019 Cadillac CTS-V's (UCA631) are manufactured from heavy-duty 1.25-inch DOM steel tubing. The open end is formed from CNC laser cut, CNC formed 3/16-inch steel plate. It features zinc-plated two-piece, X-series, heat-treated, chrome-moly, self-lubricating, Teflon-lined rod ends for reduced deflection and increased articulation. This design gives you a lightweight, strong control arm that greatly improves performance, ensuring more power gets to the tires.

BMR Suspension designed the UCA631 to work well for street performance and drag race, and road race applications. The stock control arms flex under load giving you inconsistent launch characteristics. Combine this with soft bushings that have massive amounts of deflection and you're left with poor performance. The UCA631's lightweight, yet strong construction eliminates control arm flex, giving you much improved repeatability on the street or starting line. BMR's rod ends allows for fine-tuning and bind-free suspension articulation needed for superior handling. This means better throttle response, quicker 60-foot times, and improved all-around performance.
