The Powerflex adjustable front arm inner bushes (PFF40-502G) provide precise control of front suspension geometry on Mercedes-Benz C-Class (W203), CLK (W209) and SLK (R171) models, including AMG variants (C32, C55, CLK55, CLK63 and SLK55).
Made from high-performance black polyurethane (Black 95A Durometer), they incorporate CNC-machined eccentric stainless-steel inner sleeves and are supplied with a dedicated adjustment spanner. This system allows the front-axle caster to be adjusted by +/- 1°, increasing the adjustment range by 50% compared with the original bushes. It can correct suspension geometry after lowering or optimise the tyre contact patch and steering feedback for performance driving.
