Ford/Chevy/Dodge U-Bolt Plates for 3" Springs

Heavy-duty U-bolt plates for full-size leaf springs and multiple axle sizes.

These U-bolt plates are designed with standard 3" wide full-size Ford, Chevy, and Dodge leaf springs in mind, but they'll easily accommodate anything from 2.75" to 3" wide. Whether you're doing a spring-over or spring-under setup, these plates offer solid strength and fitment flexibility for a wide range of builds.

Each plate is cut from 3/8" hot-rolled P&O steel and includes 3 center pin positions, letting you dial in your wheelbase without redrilling. They'll fit axle tubes from 2.5" up to 4.125" in diameter, and accept 9/16" to 5/8" U-bolts — though we always recommend going with 5/8" for the added strength. These are made to handle trail abuse, not just look good in a parts bin.
