Forged Alloy Front Lower Arm Inner Bushings

The K-MAC 503416.-1i front lower arm inner bushings are engineered to provide precise adjustment of camber and caster on select Mercedes-Benz models. Designed as a direct replacement for OEM bushings, these forged alloy components address common suspension shortcomings that lead to premature edge tire wear and steering pull. This kit is particularly beneficial for vehicles experiencing issues related to altered ride heights, load carrying, or the fitting of wider profile tires. Unlike traditional adjustment methods that often require time-consuming arm removal and imprecise offset bushing installation, K-MAC's patented design allows for on-vehicle adjustment. The unique K-MAC design allows for precise single-wrench adjustment directly on the alignment rack, under load, and without the need to remove the suspension arms or use special tools. These bushings offer significantly improved load-bearing and impact resistance compared to OEM rubber bushings. They also incorporate mono-ball, 2-axis, self-aligning capabilities to ensure proper suspension arm travel without binding, which can occur with urethane or small spherical bearings. This results in improved brake and steering response, enhanced traction, and the ability to fine-tune understeer/oversteer characteristics for both daily driving and track use. This kit specifically fits the Mercedes-Benz W205 chassis, including models such as the C220, C250, C300, C400, C450, and C43 AMG (4MATIC) from model years 2015-2022. The package includes a bush extraction tool to facilitate installation. For combined Camber and Caster adjustment, the K-MAC #503416-K kit is available.
