Launching harder, reducing wheel hop, and adding cornering consistency to your 2008-2017 Dodge Challenger is easy with upper control arms from BMR Suspension. Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMRs rod ended, single-adjustable trailing arms for Challengers (UCA111) are manufactured from heavy-duty 1-inch DOM steel tubing. The open end is formed from CNC laser cut, CNC formed 3/16-inch steel plate. This design gives you a strong trailing arm that greatly improves performance. The UCA111 features zinc-plated two-piece, X-series, heat-treated, chrome-moly, self-lubricating, Teflon-lined rod ends. It also features 304 stainless steel, custom designed rod end spacers. This design provides reduced deflection, increased articulation, and an all-around improvement in performanceBMR Suspension designed the UCA111 to work well in street performance, drag race, and road race applications. The stock trailing arms flex under cornering loads giving you inconsistent handling characteristics. Combine this with soft bushings that have massive amounts of deflection and youre left with poor performance. The UCA111s heavy-duty construction eliminates trailing arm flex, giving you much improved repeatability on the street, starting line, or in the corners. BMRs rod ends allows for fine-tuning and bind-free suspension articulation needed for superior handling. These are the perfect upgrade for the enthusiast looking to improve performance at an affordable price, while maintaining acceptable NVH levels and ride quality.
