McLaren MP4 12C Front Shock Absorber 11B0705CP 03

the part number 11B0705CP 03 refers to the Front Shock Absorber (Damper) for the McLaren MP4-12C.

This part is a core component of McLaren’s revolutionary ProActive Chassis Control (PCC) system. Unlike standard supercars, the 12C does not use traditional anti-roll bars; instead, it uses a complex hydraulic network connecting these dampers to manage body roll and ride comfort simultaneously.

1. Technical Identification

• Part Number: 11B0705CP 03

• System: ProActive Chassis Control (PCC).

• Position: Front (The .03 suffix usually indicates the most recent engineering revision, addressing seal durability issues found in the .01 and .02 versions).

• Function: A double-acting hydraulic damper that is interconnected to the car’s central hydraulic spheres (accumulators).

• Compatibility: Specifically for the MP4-12C (Coupe and Spider). While the 650S dampers look similar, they have different valving and are not a direct “plug-and-play” swap without matching the rest of the 650S suspension software and accumulators.
