The RAM DS and DT generations have been hugely popular and rank among the best in the fiercely competitive full-size truck market. That said, they do have some weak links as they accumulate mileage, all of which show up earlier for those that tow and haul. Among these are the RAM's rear trailing arm bushings which degrade quickly and compromise handling, load-carrying, and ride comfort. In addition to offering the stand-alone bushings SuperPro has elected to offer complete arm assemblies. These offer a DIY or fitter-friendly installation that is quick and painless while replacement the complete assembly with new arms that feature SuperPro's industry-leading lifetime bushings pre-installed in the complete arms. Worn bushings allow significant deflection and movement leading to slower responses, a sloppy drive, irregular and excessive tire wear and diminish every facet of the way your vehicle drives “ while contributing to driver frustration and fatigue. SuperPro's polyurethane bushings are the culmination of nearly 5 decades of suspension expertise and development in Australia's harshest terrain. Designed with durability as a paramount feature we also bring ride and passenger comfort to the forefront of our development. Your vehicle should treat you as well on the way to and from the trail as it performs on your adventure. Our designs and material compositions retain OEM levels of noise and harshness isolation while delivering superior performance and road manners in all conditions.
