UMI's 362224 trailing arm kit is the perfect solution for the 1978-1996 GM B-Body factory wheelbase issue. By extending the arms 5/8", UMI has created a kit that effectively repositions the wheel within the wheel house. The extended length rod end adjustable upper trailing arms control pinion angle and lateral location, complementing the extended length lowers. This kit allows for the use of the factory driveshaft and is proudly made in the USA.
