SuperPro calls this a 'hybrid design' and it truly is. While from the outside this looks like a blue polyurethane puck, the construction inside is quite advanced. This design features a large heavy duty spherical metal ball joint encased in SuperPro's advanced polyurethane. This yields a number of benefits - first and foremost - you get full articulation of the control arm. Other vertical pivot designs offer a limited range of motion once installed compromising suspension travel and binding at the extremes of their range. The SuperPro Duroball design gives you the full range of motion like the OEM design, but in a more rigid solution with greater durability and a longer service life.;SuperPro also manages to offer a solution here that caters to road and track cars alike. While the STI will never be a luxury barge that floats silently down the freeway - maintaining some civility on the road is key to building a high performance street car you can live with on a daily basis. SuperPro's hybrid design offers exactly that - all of the performance enhancement you expect from a spherical bearing option, increased caster enhancing grip and feedback, and SuperPro's advanced polyurethane insulating the metal bearing to preserve some tranquility in the cabin.

Pair of SuperPro Duroball Front Lower Control Arm Bushings - 1 needed per Vehicle

This kit retains the standard alignment - DURO3738K offers the same design, but offers an additional 0.5° of caster for additional front grip and enhanced steering feel. The standard version does not compromise the articulation or range of motion of the front control arm - allowing factory fit and function with enhanced performance.
