Launching harder, reducing wheel hop, and adding cornering consistency to your 2008-newer Dodge Challenger is easy with upper trailing arms from BMR Suspension. Stock stamped steel trailing arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMRs polyurethane, non-adjustable trailing arms for Challengers (UTA110) are manufactured from heavy-duty CNC laser cut, CNC formed 3/16-inch steel plate. This design gives you a strong control arm that greatly improves performance. Greasable, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMRs bushings are internally fluted, which allows grease to evenly coat the inner sleeve. These flutes also direct grease to the outer edge of the bushing, keeping the thrust surface lubricated. This efficient lubrication ensures quiet, reliable operation over the life of the bushings.
