Borgeson 510964 - Borgeson Pin & Block U-Joints

The advantage to the pin and block style of universal joint is a high strength to weight, size and cost ratio. These U-joints are manufactured from high strength billet alloy heat treated steel. Because the u-joints use pivot pins and blocks instead of sealed needle bearings, they must be checked and lubricated every time the vehicle is driven. These u-joints are not recommended for street use.
