The Synergy 2003-2013 Dodge Ram 1500 / 2500 / 3500 Adjustable Track Bar is designed to increase the strength between the frame and axle and is fully adjustable to help center the axle underneath your truck. It can adjusted from 38.625″ (.25″ shorter than stock) to 39.438″. This allows the track bar to be used when lowering trucks for truck pull & race applications (up to 3″ lower than factory height) and lifted applications up to 6.0″ over factory height for off road use. The bar is bent to clear most aftermarket differential covers and uses maintenance free Synergy Dual Durometer bushings on both ends.
