Custom Bent U-Bolts Made to Order

These u-bolts are for suspension, leaf spring and body mounting primarily, but have hundreds of other uses.

From 3/8 to 1 1/4 inch diameter threads.

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 manufactured by rolling between dies. This makes the non-threaded part of the stock slightly smaller in diameter than the diameter of the threads.

Please note that these are custom made ubolts and are not returnable.
We do not sell any form of Stainless Steel Material.
We do not offer any type of plating or galvanizing. All ubolts are oil finish.
