Overview

The K-MAC 505126-M is a rear camber and extra toe adjustable bush kit designed for Mercedes C254/X GLC 200-300 models from 2022-2026, including 4MATIC variants. This set of four bushings replaces the highest wearing bushes, offering significant adjustment capabilities.

K-MAC has been resolving OEM suspension shortcomings since the 1960s. This kit provides a "single wrench" adjustment directly on the alignment rack, under load. Unlike older methods requiring arm removal and repeated adjustments, these bushes are inserted in any offset position and then adjusted via a bolt head for precise settings. The kit includes bush extraction tools and a majority of installations do not require arm removal.

The K-MAC 505126-M is a rear camber and extra toe adjustable bush kit engineered to address the lack of factory adjustment in Mercedes C254/X GLC 200-300 models (2022-2026, including 4MATIC). This kit replaces high-wear OEM bushes, providing precisely adjustable camber and toe settings. Traditional suspension adjustments have historically been time-consuming, often requiring arm removal and pressing in offset bushes. K-MAC revolutionizes this process with patented designs that allow for insertion in any offset position, followed by precise adjustment using a single wrench while the vehicle is on the alignment rack. The kit includes essential bush extraction tools, and in most cases, installation can be completed without needing to remove the control arm. They also incorporate Mono ball / 2 Axis / Self-aligning capabilities without relying on oil or air voids. This design significantly improves brake and steering response, corrects costly premature edge tire wear, and fixes steering pull. The adjustable lower arm camber bushings also provide extra track width and negative adjustment to reduce understeer, beneficial for performance driving. This kit is specifically designed for the Mercedes C254/X GLC 200-300 models manufactured between 2022 and 2026, including those equipped with 4MATIC all-wheel drive.
