2.5 Inch Poly Flex Joint Upgrade. Daystar Poly Flex joints are the answer for anyone that needs a strong and silent pivot point. Like a traditional Heim joint, the Poly Flex joint utilizes a spherical ball captured inside a steel outer shell. Unlike Heim joints, however, Poly Flex Joints encapsulate the spherical ball in a special blend of polyurethane.

Housed in a steel outer shell, the joint allows a greater range of movement without binding in its attachment points. Also unlike a Heim, the Poly Flex joint does not make noise over time and is completely rebuildable Poly Joints feature a Polyurethane bushing that is specially designed to move as the suspension articulates. Available with threaded studs or a weld-on version, these joints are perfect for any fabricator that needs a high-articulation pivot point that remains silent and serviceable.
