Product Details

The Energy Suspension 4-5128G is a high-performance sway bar bushing set engineered with Hyper-Flex polyurethane technology. Designed to replace factory rubber bushings, this set delivers improved handling response, reduced body roll, and enhanced steering precision. The advanced polyurethane formula provides the optimal balance of firmness and compliance for superior suspension performance.

Key Features:

  • Hyper-Flex polyurethane construction resists compression and maintains consistent performance
  • Application-specific durometer rating ensures proper suspension geometry and response
  • Superior resistance to oil, road salt, chemicals, and environmental contaminants
  • Will not rot, crack, or deteriorate like OEM rubber bushings
  • Eliminates mushy handling and vague steering feel caused by worn rubber
  • Black finish for clean, professional appearance
  • Race-proven durability for street, track, and off-road use
  • Direct replacement design for straightforward installation

Backed by over 20 years of polyurethane engineering expertise, Energy Suspension's Hyper-Flex bushings provide long-lasting performance that maintains suspension geometry and handling characteristics far longer than factory rubber components. Ideal for performance upgrades, restorations, or replacement of worn OEM parts.
