Bearing Precision With Polyurethane's Livability

Control arm bushings form the vital pivot and link between all core suspension components, and SuperPro increases both performance and precision over traditional elastomer bushings with their compound DuroBall bushing assembly. Using an isolated spherical bearing encased in polyurethane, this design provides the precision and articulation of a genuine bearing while retaining the NVH mitigation of SuperPro's bespoke polyurethane compositions. That combination is difficult to achieve with either a pure bearing or pure bushing design alone. It's a straightforward improvement that's easy to appreciate once it's installed.

The Real Cost of Worn Bushings

Worn bushings allow significant deflection and movement, leading to slower responses, a sloppy drive, irregular and excessive tire wear, and diminished performance in every facet of how your vehicle drives. That wear is accelerated, and its impact even greater, in vehicles running larger than stock wheels and tires. Replacing worn bushings with this DuroBall design addresses that deflection at its source rather than letting it compound into worse handling and tire wear over time. That combination of durability and performance is what makes it worth the upgrade.
