Energy Suspension 3-2137R Heavy Duty Shackle Set - Red

The Energy Suspension 3-2137R Heavy Duty Shackle Set replaces your worn factory rubber shackle bushings with performance polyurethane components engineered to restore handling precision and durability. Manufactured from Energy Suspension's proprietary Hyper-Flex polyurethane, these shackles resist the crushing forces, oil contamination, and atmospheric degradation that cause OEM rubber bushings to deteriorate and compress over time.

Key Features:

• Hyper-Flex polyurethane construction resists compression, cracking, and permanent deformation
• Application-specific durometer formulation optimized for shackle performance
• Impervious to road salt, oil, chemicals, smog, and ozone exposure
• Eliminates the mushy handling and vague steering response caused by worn rubber bushings
• High-visibility red finish for custom appearance under your vehicle
• Proven performance in racing, off-road, and street applications
• Direct replacement for factory shackle bushings with no modifications required

Energy Suspension has over two decades of experience formulating polyurethane suspension components that deliver race-proven durability and performance. Unlike OEM rubber components that break down from exposure and stress, Hyper-Flex polyurethane maintains its performance characteristics throughout its extended service life, making it ideal for modified vehicles, restorations, and demanding driving conditions.
