Custom Bent U-Bolts Made to Order from 3/8 to 1 1/4 inch diameter thread

U-bolts we make are custom per your order and are not returnable.

Please note that the “L” measurement (length) may be slightly longer and is not exact depending on total rod length. The reason the “L” measurement may be longer, we add “C” and “L x 2” measurements to get the total material length which is made in even lengths, 22, 28, 38 etc.

These u-bolts are for suspension, leaf spring and body mounting primarily, but have hundreds of other uses. We bend our own u-bolts on a hydraulic bender cold so the grain of the metal stays oriented in the right direction for maximum strength. The stock rod may be bent in many shapes but the most common shapes are SQUARE TOP, SEMI-ROUND TOP and ROUND TOP. The threads are SAE (fine) and are manufactured by rolling between dies. This makes the non-threaded part of the stock slightly smaller in diameter than the diameter of the threads and are not thread-able beyond the way they are. We do not stock any form of stainless steel material and do not offer any type of plating or galvanizing. All u-bolts are oil finish. 

U-bolts up to 9/16 are Grade 5, while 5/8 and above are Grade 8.
