Energy Suspension Hyper-Flex Polyurethane Leaf Spring Shackle Bushing Replacement Set

Energy Suspension Shackle Bushing Sets bring the proven performance of Hyper-Flex® polyurethane technology to one of the most critical and wear-prone areas of the leaf spring suspension system. Engineered as a direct upgrade over factory rubber bushings, these sets restore proper suspension geometry and deliver a level of durability that OEM rubber simply cannot match.

Why Hyper-Flex® Polyurethane?

Factory rubber bushings dry out, crack, and collapse over time — allowing the leaf spring shackle to move out of alignment and introducing unwanted flex, vibration, and imprecise handling into your suspension. Energy Suspension's Hyper-Flex® compound is formulated to maintain its shape and resilience under the heaviest loads, across extreme temperature ranges, and in the harshest operating environments. The result is a suspension that feels tighter, more predictable, and more controlled — mile after mile.

Key Features:

• Hyper-Flex® polyurethane construction outlasts OEM rubber bushings for long-term reliability
• Resists deterioration from road grime, oil, salt, UV exposure, and atmospheric pollutants
• Will not crack, rot, collapse, or deform the way rubber bushings can
• Maintains proper suspension alignment and geometry under varying load conditions
• Reduces wheel hop and improves rear axle stability and control
• Engineered to OEM tolerances for a precise, modification-free installation
• Suitable for street, tow, off-road, and performance applications
• Made in the USA by a recognized world leader in performance polyurethane suspension technology

Each set includes all bushings needed for a complete shackle replacement, matched to the exact specifications of the application. Available in multiple variants to suit both function-focused builds and show-quality restorations. As the most recognized name in polyurethane suspension components, Energy Suspension backs these bushing sets with a limited warranty against defects in workmanship and materials.
