Energy Suspension 3-2137G Heavy Duty Leaf Spring Shackle Set Black

The Energy Suspension 3-2137G Heavy Duty Shackle Set replaces factory rubber leaf spring shackles with high-performance polyurethane components designed to eliminate the flex and degradation common with OEM rubber bushings. Manufactured from Energy Suspension's proprietary Hyper-Flex polyurethane material, these shackles deliver improved suspension response, more precise handling, and dramatically extended service life compared to original equipment.

Key Features:

• Hyper-Flex polyurethane construction resists rot, deterioration, and compression from oils, road salt, and atmospheric contaminants
• Heavy duty design withstands extreme torque and weight loads without the mushy flex of rubber bushings
• Maintains suspension geometry and alignment for consistent handling characteristics
• Black finish complements both show and performance applications
• Race-proven durability for street, off-road, and track use
• Direct replacement design for straightforward installation

Ideal for vehicles experiencing worn or deteriorated leaf spring shackle bushings, this set restores like-new suspension feel while providing long-lasting performance that outlasts conventional rubber components. The carefully formulated durometer provides the optimal balance of compliance and control for leaf spring applications on trucks, SUVs, and rear-wheel drive vehicles.
