McLaren P1 Front Left Right Shock Absorber 12B0212CP 12B0211CP

McLaren P1 is a highly specialized task, as these parts are integral to the car’s RaceActive Chassis Control (RCC) system. The part numbers 12B0212CP (Front Left) and 12B0211CP (Front Right) refer to the adaptive hydraulic dampers that allow the P1 to adjust its ride height and stiffness in milliseconds.

Technical Specifications: P1 Hydraulic Dampers

The P1 does not use traditional coil springs or anti-roll bars. Instead, it uses a complex interconnected hydraulic system.

• Front Left (LH): 12B0212CP

• Front Right (RH): 12B0211CP

• System Type: Interconnected Hydraulic Suspension.

• Function: Controls heave, roll, and pitch hydraulically. In Race Mode, these dampers lower the car by 50mm and increase spring stiffness by 300%.

Buying & Maintenance Intelligence

• Availability: These parts are rarely stocked by general retailers. They are typically sourced through McLaren Heritage programs or specialized exotic parts brokers (e.g., Eurospares, Scuderia Car Parts).

• Condition: If buying used/recycled, it is vital to check for leaks at the hydraulic seals. Because the system operates under extreme pressure, even a minor weep can lead to a total system failure.

• Installation: Replacing P1 shocks requires a full hydraulic system bleed and recalibration using the McLaren Diagnostic System (MDS). This is not a standard mechanical job and must be performed by a certified technician.
