Our axle truss system is defiantly in a league of its own. Unlike the common truss's that you see on the market that only have one piece if bent steal that has to be tied into the differential cover to make it suitable for use, ours is has a fully boxed design that makes it incredibility strong. These are available in a .375" thick model and a .25" thick model. They are also available in 3 heights to clear the differential. All trusses have a .375" thick base plate. The truss system was designed on state of the art 3D CAD software, laser cut and bent with a CNC Press Brake. Like all of our products our trusses are made from high-strength American steel plate. If you shop around you will find that our truss are the best product for your 4 link needs.
