Custom U-Bolts & J-Bolts

At Best Deal Springs, we build custom U-bolts and J-bolts at all of our four locations throughout Utah. We have been building U-bolts for over 40 years! We can bend U-bolts for your pickup truck or semi-truck’s leaf springs, tractors, agricultural and construction equipment, or just a project you are working on. Best Deal Springs has got you covered when it comes to custom U-bolts and J-bolts. We can build custom u-bolts and j-bolts to any size and specification you need!

Top-Quality Materials for U-Bolts

The steel material we use is made specifically for U-bolts and J-bolts. It is high-quality, made-in-the-USA, and it is cold-drawn. This enables it to be bent into shape without the need for heating. The rods also have rolled-in threads rather than cut-in threads, which provides a more durable thread for long-lasting performance. The rods we use were designed specifically for U-bolts, unlike many other U-bolts out there that simply use whatever rod will function. Sizes ⅜” to 9/16″ are a grade-5 equivalent, while sizes ⅝” to 1-¼” are a grade-8 equivalent.

Available U-Bolt & J-Bolt Diameters

3/8″, 7/16″, 1/2″, 5/8″, 3/4″, 7/8″, 1″, 1-1/8″, 1-1/4″

Available Bends for U-Bolts & J-Bolts

U-bolts can be bent to fit square, semi-square (semi-round), round, and special bends up to 7″ wide.
