Track Rod End Boot – Polyurethane for the steering track rod end ball joint.

This polyurethane boot fits over the track rod end housing, sealing the ball joint against ingress of dirt, water, and road contaminants while retaining grease within the socket. Polyurethane provides greater resistance to ozone, oil, and heat compared to standard rubber. A cracked or missing boot allows contamination into the ball joint, leading to accelerated wear and eventual joint failure.
