Leaf Spring Parts & U-Bolt Parts

We’re proud to offer a wide selection of high-quality leaf springs and U-bolts that supplements our suspension parts line. Leaf springs support the weight of the vehicle and absorb shocks from the road. U-Bolts are used to secure leaf springs to the vehicle’s axle and maintain the integrity of the suspension system.

Boost your suspension with Abby Spring Service and Miro Parts. From agricultural equipment to light-duty pickups to mighty Mack trucks, we’ve got a huge range of springs and custom U-bolt bending capability to cater to your needs.

U-Bolts Parts We Carry:

We Build Custom U-Bolts In House

With over 25 years of expertise, Abby Spring Service and Miro Parts specializes in crafting U-bolts for a wide range of applications, from pickup trucks to semi-trucks, tractors, and construction equipment.

Our custom U-bolts can be tailored to any size and specification you need, crafted from cold-drawn, high-quality material. The rod we use is specifically designed for U-bolts, unlike others who may simply use whatever will function. For a more durable thread, the rod rolls in threads rather than simply cutting them.

Sizes 3/8″ – 9/16″ are a grade 5 equivalent, while sizes 5/8″ – 1-1/4″ are a grade 8 equivalent.

Available Diameters

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

Types of U-Bold Bends

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

See chart below for how to measure u-bolts.

A. Measure diameter of the U-bolt rod
B. Measure inside distance between the U-bolt legs
C. Measure length of the U-bolt leg
D. Determine type of bend (round, square or semi-round)
