Firm Bushing 88A Duromtr

The Firm Bushing 88A Duromtr from Energy Suspension is a high-performance polyurethane isolator bushing engineered to replace worn OEM rubber components and reduce unwanted chassis movement in your vehicle's suspension system. Designed for serious mechanics and automotive enthusiasts who demand precision handling and improved suspension response, this bushing eliminates the compliance that stock elastomers introduce, delivering direct feedback and tighter control during aggressive driving or daily performance use.

Constructed from Energy Suspension's proprietary 88A-durometer polyurethane material bonded to a cadmium-plated steel core, the Firm Bushing 88A Duromtr resists deflection and maintains geometry consistency across a wide temperature range and driving condition spectrum. The 0.5-inch inner diameter and 2.5-inch outer diameter design fits standard 0.875-inch mounting holes, making this a direct replacement for original equipment on countless vehicle platforms. The polyurethane formulation offers superior durability compared to natural rubber—resisting cracking, ozone degradation, and fluid contamination—while the cadmium-plated steel inner core ensures corrosion resistance and long-term structural integrity in corrosive road salt environments.

Vehicle modifiers, restoration specialists, and performance-minded owners benefit most from this pair of bushings when upgrading suspension control arms, sway bars, or chassis isolation mounts where factory compliance is unacceptable. Installation is straightforward—press-fit or bolt replacement depending on application—and requires no special tools beyond a hydraulic press or basic mechanical equipment. Whether you're tightening up a street machine, improving handling on a weekend track car, or restoring a classic with modern suspension performance, the Firm Bushing 88A Duromtr delivers measurable improvements in response time and elimination of bushing play that factory rubber simply cannot match.
