The front coilovers have a total shock travel of 5.4", but only add about an inch or two inches to factory wheel travel. Front wheel travel is limited by the CVs, tie rods, and LCAs and front limit straps aren't really necessary. As for rear bump stops, they're usually not required unless you're driving extremely aggressively off-road over rough terrain, especially if you're using aftermarket leaf packs or add-a-leaf kits that increase rear travel. Unfortunately, we don't have a lot of information on the Hellwig sway bars and how they effect travel or suspension performance, since we're not a Hellwig dealer.
