G-WAGEN POLY CASTER ARM BUSHING V2 (FRONT) - G WAGEN - W463 up to 2018
Restore Steering Precision to Your Lifted G-Wagen
When you lift your Mercedes-Benz G-Class, the altered suspension geometry often introduces a vague, wandering steering feel that compromises the legendary, commanding presence of the vehicle. The Eurowise Poly Caster Arm Bushings V2 correct your front-end caster angle, eliminating steering drift and restoring the razor-sharp handling your G-Wagen deserves.
The Evolution of Alignment Stability
Engineered specifically for the demanding architecture of the classic W463 chassis, the Eurowise Poly Solid-Mounted Radius Caster Correction Bushing V2 represents over a decade of rigorous real-world testing and refinement. While traditional vulcanized rubber factory bushings flex, wear out, and degrade under stress, this next-generation upgrade offers an uncompromising, solid-mounted solution.
We have re-engineered this V2 bushing as a true, one-piece press-in assembly. Each unit features a high-tensile, solid aluminum outer sleeve paired with an injection-molded polyurethane core that is molecularly bonded directly to the ring and inner pin. This creates a highly durable, impervious boundary against trail debris and highway vibrations alike.
The tactile feel behind the wheel is transformed: crisp, predictable, and firmly planted. To ensure a seamless integration into your front suspension setup, every kit includes a proprietary custom alignment jig—eliminating the guesswork and ensuring a flawless, precision-engineered press-in installation every single time.
