Launching harder, reducing wheel hop, and adding cornering consistency to your 2008-2019 Dodge Challenger is easy with upper trailing arms from BMR's suspension. Stock stamped steel trailing arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMRs rod ended, on-car adjustable trailing arms for Challengers(UTA112) are manufactured from heavy-duty 1-inch DOM steel tubing with TIG-welded Chrome-moly tube adapters. This design gives you a strong trailing arm that eliminates deflection and greatly improves performance. The UTA112 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's suspension designed the UTA112 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 UTA112s 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 at any power level. When performance is a must, rely on BMR's suspension!BMR's suspensions UTA112 on-car adjustable upper trailing arms are available in red and black hammertone powdercoat for long-lasting good looks.
