This retrofit kit is designed to update Synergy 8550-01 track bars with polyurethane style bushings to our Dual Durometer Bushing (DDB) on 2003-2013 Dodge 4x4 trucks. The kit consists of two step down washers, one Dual Durometer Bushing (DDB), and grade 9 hardware. The step down washers are oversized requiring the frame side track bar bracket bolt hole to be drilled out. The washers will correct ovaled out bolt holes and add material in this area for extra strength. Washers are made from 303 stainless and can be bolted or welded in.
