U-bolt spring plates will be used on many suspension designs that use leaf springs and U-Bolts. U-bolt plates can be used on the top of the spring, the bottom of the axle, or both. U-bolt plates will allow the clamping force of the U-bolts to be spread out over a larger area, preventing damage. The use of U-bolt plates prevents breakage of the leaf springs by limiting the possibility of high stress points where the leaf spring and U-bolts meet and allows force to be effectively transferred to the axle housing without causing cracks or damage.
U-bolt top plates are used to protect the leaf springs and to guide the position of the U-bolts. Top plates will have an opening to position the plate over the center bolt and there will be a channel to locate each U-bolt on the plate. The channels will hold the U-bolts in a position that keeps them square to the axle when they are secured. Some top plates will include bump stop towers to help limit suspension travel and they may also provide shock absorber or torque rod mounting locations.
U-bolt bottom plates allow the clamping force to be applied to the axle on suspensions that orient the U-bolts downward with the bend at the top curving over the leaf spring. The bottom plate will be contoured to match the curve of the axle to evenly spread the force and the U-bolts will pass through the plate. When washers and nuts are secured to the U-bolt they will push against the plate as they are tightened clamping the axle and leaf spring pack together.
If at some point during the life of the suspension the U-bolts loosened there may be wear in both the top and bottom U-bolt plates. As suspension components shift, they will cause wear between the components that are moving. When servicing the suspension worn top and bottom plates should be replaced to prevent damage to new components.
When replacing U-bolt spring plates, it is usually best to use an OEM part number or a casting number and then measuring to verify the correct replacement.
