After fighting crazy traction issues since adding the Procharger , I've been in need of doing what it takes to keep rear end more stable.. My truck is lowered with a flip kit so clearance is a concern. I stumbled across a thread where these where used with great results and liked the fact that they were designed for flip kit applications. The quality is amazing and shocked by how much it improved the characteristics of the truck. The truck used to ride choppy at times due to the shocks that were supplied with my lowering kit. The truck rides night and day difference better with the extra support the bars added and the truck keeps the tires planted !!! No more skipping the tires till 65 mph
