How To Measure A U-Bolt
U-bolt diagrams, regardless of the bend type, are measured in the same manner as shown here. The U-bolt size is given as Diameter(A) x Distance(B) x Leg Length(C).
Additionally, the bend type must also be given to avoid problems in the specifications of semi-round bend shapes.
Forged top U-bolts are best ordered by application and leg length since the type of forging is usually unique to the particular application and must be maintained to provide proper fit and clearance.
THREE TYPES OF U-BOLTS
Three basic types of bends are used on U-bolts depending on the suspension design and the shape of the mating parts:
Additionally, each of these bend types may use forged material. This is used primarily where additional clearance is required between the U-bolts and, for example, the frame.
