SuperPro 2018 Kia Stinger Base Front Radius Arm w/ Caster Bushing Set

These SuperPro radius arm bushings are designed to give your 2018-2023 Kia Stinger Base a notable improvement in front-end handling. The key here is the 'offset' design, which introduces a small but significant amount of positive caster into the suspension geometry. This isn't just a spec on paper; it directly translates to a vehicle that tracks straighter on the highway, requiring less constant correction from the driver, and it helps the steering wheel return to center more readily after a turn.

Beyond straight-line tracking, this caster adjustment also enhances cornering. As you turn, the wheels gain dynamic camber, which means more of the tire's contact patch stays planted on the road when you're leaning into a corner. This helps prevent the tire shoulder from rolling over, maintaining better grip. You'll also notice a more substantial, connected feel through the steering wheel, especially as you come off-center, giving you a clearer sense of the car's limits. SuperPro has developed these polyurethane bushings with nearly 50 years of experience, focusing on durability for tough conditions while maintaining OEM levels of comfort and noise isolation.
