If you are looking for the best in a forged polyurethane joint Barnes 4wd has you covered, we designed these to be the strongest joints on the market! They are forged from one piece of 4130 chromoly, making them much stronger than other inferior joint designs that have the threaded shank welded on. They have a 2 5/8 mounting width, are available with a right hand or left hand 1 ¼-12 threaded shank that is 2 3/4" long, and are available for use with a 5/8 or 9/16 bolt. A yellow zinc plating is applied to help prevent corrosion, the inner sleeve has the same coating and is a one piece machined design, not a rolled piece of uncoated steel like most polyurethane joints include. A grease fitting has been integrated to make lubrication an effortless task. These joints are perfect to use on the frame end of your suspension links to help stop the transmission of vibration into the passenger compartment. This is a direct replacement for a 1 1/4" heim joint.
