Construction & Design

The bushing features a dual durometer design, combining two different hardness levels of polyurethane to optimize performance. The softer inner material absorbs vibrations and reduces noise, while the firmer outer layer maintains structural integrity and suspension geometry under load. This combination ensures that the bushing remains flexible enough for articulation but strong enough to resist premature wear and deformation.

Manufactured with precision molding techniques, the bushing maintains tight tolerances for a perfect fit on the Jeep Wrangler’s front upper control arms. The use of high-quality polyurethane materials provides excellent resistance to oil, dirt, and road contaminants, extending the service life of the component.
