AST PSB 1120 Polyurethane Leaf Spring Bushing

The AST PSB 1120 is a premium polyurethane leaf spring bushing engineered to replace worn or damaged rubber bushings in your vehicle's suspension system. PSB specializes in manufacturing polyurethane problem solving bushings that are not just factory replacement parts, but actually solve many complex and inherent design problems in new vehicle suspensions.

Key Features:

• Polyurethane construction is stronger and lasts longer than standard rubber bushings
• Features sleeves that freely rotate to enhance longevity
• Manufactured with the highest grade of polyurethane with durometer designed to fit the application, with quality and lifespan that far exceeds the original part
• Quick installation typically takes 1-5 minutes after removal of original bushings

Leaf spring bushings are critical components that isolate the leaf spring from the mounting hardware and connect the springs to the vehicle frame. When rubber bushings wear out, they can cause clunking noises, steering wander, and poor suspension performance. Upgrading to polyurethane bushings provides superior durability and maintains proper suspension geometry for improved handling and ride quality.
