Summary: The Energy Suspension Rear Leaf Spring Bushing set is engineered to replace soft, prone-to-failure factory rubber components with high-performance Hyper-Flex™ Polyurethane. By upgrading to this Black polyurethane set, GMC K3500 owners can restore proper ride height and eliminate the slop associated with worn bushings, ensuring the vehicle remains in control during heavy hauling or off-road articulation. These components are designed to last 5 to 10 times longer than conventional rubber, providing a significant increase in durability and suspension stability. This kit is specifically designed for models with a 1-3/8 inch outside diameter frame shackle and a 1-3/4 inch main eye.

Features

• Hyper-Flex™ Polyurethane Material: High-grade performance polyurethane provides superior resistance to oils and road grime while ensuring the material lasts 5 to 10 times longer than conventional rubber components.
• Integrated Shackle Bushings: The inclusion of shackle bushings provides enhanced leaf spring articulation and reduced noise to ensure the suspension functions properly under load.
• Precision Machined Sleeves: Included steel sleeves provide a rigid pivot point to ensure consistent suspension geometry during braking and acceleration.
• Optimized Control: Engineering-grade polyurethane provides increased firmness over rubber to ensure the vehicle remains stable when maneuvering through turns and over bumps.
• Limited 7 Year or 750,000 Mile Warranty: Comprehensive coverage provides long-term peace of mind and reflects Energy Suspension’s commitment to quality assurance.
