2.5 Ton Rockwell Axles are a great choice but to get the most out of them you need suspension components that are uniquely designed for their unique layout. Our Rockwell link Tower will give you a 2.625" mounting width and the center of the joint will be 8.5" above the top of the axle tube. The entire Barnes 4wd Rockwell Bracket line up is made entirely of 3/8" American Steel.
