Summary: The Energy Suspension Rear Leaf Spring Bushing Set is engineered to replace soft, prone-to-failure OEM rubber components with high-performance Hyper-Flex™ Polyurethane. Specifically designed for the GMC K35, these bushings address common issues like leaf spring sag and poor articulation by providing a more stable pivot point. This Red performance-series kit ensures your suspension remains in control during heavy hauling or off-road maneuvers, lasting 5 to 10 times longer than conventional rubber components. By maintaining proper spring alignment, these bushings restore ride height and improve overall vehicle handling.

Features

• Hyper-Flex™ Polyurethane Material: High-grade performance polyurethane provides superior durability and resists environmental breakdown to ensure it lasts 5 to 10 times longer than conventional rubber components.
• 1-1/2 Inch Outside Diameter Frame Shackle: Precision-sized shackle bushings provide a secure fit for the frame-side mount to ensure improved leaf spring articulation and reduced noise.
• Included Steel Sleeves: High-quality sleeves provide a smooth bearing surface for the bushing to ensure the suspension can function properly without binding.
• Limited 7 Year or 750,000 Mile Warranty: Comprehensive manufacturer coverage provides peace of mind and long-term quality assurance for your GMC K35.
