Overview

This kit allows for on-car adjustment without disassembly, significantly improving brake and steering response. These bushings replace the highest wearing components in the OEM suspension.
Show original supplier description
The K-MAC 502616 K is a precisely adjustable front camber and caster lower arm inner bushing kit designed for Mercedes-Benz W204 ('07-'14), X204 ('08-'16), C207/A207 ('09-'17), and R172 ('11-'19) models, including AMG and 'Black' Series variants. This kit addresses the OEM suspension's lack of adjustment, which can lead to costly premature edge tire wear and steering pull. Featuring a unique, patented K-MAC design, these bushings allow for precise, single-wrench adjustment directly on the car without the need for arm removal or special tools. The caster bushings are designed as Monoball/2 Axis components, which significantly improve brake and steering response with a fail-safe lock system. Traditional methods of adjusting camber and caster are time-consuming, requiring arm removal and pressing in offset bushings. K-MAC's system allows for the bush to be inserted in any offset position, with adjustments made by simply rotating the bolt head to achieve the exact alignment setting. This on-car, under-load adjustment capability revolutionizes suspension tuning. The result is the ability to resolve costly premature edge tire wear, correct steering pull, and improve traction, understeer/oversteer balance, especially beneficial for track days. Unlike urethane replacements that can inhibit suspension arm travel, K-MAC's design ensures proper articulation, preventing wheel tramp and loss of traction.
