UMI Performance Rear Toe Rods
These UMI Performance rear toe rods play a crucial role in controlling the camber alignment of the rear end, preventing the tire from moving inward or outward during suspension load. Factory toe rods are often made from flimsy stamped steel with soft rubber bushings that can cause deflection, leading to erratic handling, poor traction, and possible rear tire wear. Replacing these factory arms with heavy-duty toe rods can significantly improve the stability of the suspension, traction, and braking performance. UMI Performance rear toe rods are manufactured from 1" x 2" rectangular tubing and fully TIG welded for maximum strength. They are equipped with fluted, greaseable, and low deflection polyurethane bushings from . Installation is a breeze, with these toe rods being a direct bolt-on using OEM hardware. With a durable powder coat finish and made in the USA, these toe rods are sure to enhance the performance of your vehicle.
