These are almost 2 pounds each! They are meant for the bottom of the rig, the side taking a beating now and then (all the time). We make them .25 thick with a sloped ramp shape to bring them up to the strength of our .375 Chassis tabs, we are pretty sure you can wear them out but you will be very challenged to break them. They are high enough around the bolt to give all but the very largest Heims complete protection and still short enough on the joint end to allow full articulation. these are in the popular 2.625 (2 5/8) width so any joint or Heim with missalignment can be used. Made exclusively of A50 Steel Plate for its density and strength. These are sold in pairs. If you want us to weld them choose it as an option ($10 additional charge)
