How to Measure U-Bolts on Your Vehicle
Most people aren’t aware that when they change out their leaf springs, that they should also get new U-bolts. At the same time, you don’t necessary have to wait until your leaf spring suspension runs out to have your U-bolts replaced. At any rate, whatever your reason is, if you are going to get new U-bolts, you will need to know how to properly measure the ones you currently have in order to replace them with the right one.
The main function of a U-bolt is for connecting the axle of your vehicle to the pack of leaf springs for an optimal suspension system. It kind of works like a big industrial paperclip—with threads that hold the entire suspension system together! The U-bolts are made to form around the leaf springs and stretch as the nuts are tightened down on the rod. The metal of the U-bolt is soft enough to move with the torque and pressure from the axle and the drive shaft, making is flexible enough for the leaf springs to absorb impacts along the road.
3 Types of U-Bolts
There are three types of U-bolts available. This depends on the suspension design of your truck, SUV, car, van or recreational vehicle:
When ordering your U-bolt, the manufacturer will need certain measurements. First, you need to know exactly what kinds of measurements are needed. There are three types of measurements for U-bolts: the A Measurement, the B Measurement, and the Leg Length.
A Measurement – This measures the diameter of the rod.
B Measurement – This measures the inside width of the U-bolt. It is needed to determine the type of bend rod that the manufacturer needs in order to give the U-bolt the right width.
Leg Length – The leg length measures the overall length of the U-bolt. This is determined by measuring from the highest point of the U-bolt to the last thread. It is always best to round up when measuring the leg length as the manufacturer will have a better idea of which rod to use.
