1. Technical Identification

It is important to distinguish between the two numbers you provided, as one usually refers to the casting (bare upright) and the other to the complete assembly (including bearings or bushings).

• 14B0576CP02: Typically the part number for the Rear Right Upright Assembly. The “CP” suffix indicates it is part of the 600LT/Sports Series “Carbon Program” or high-performance parts bin.

• 14B0587CP01: Often refers to the Left Side equivalent or a specific revision of the hub carrier used in later production runs.

• Material: High-strength forged aluminum, designed to handle the increased lateral loads from the 600LT’s aero and stickier Trofeo R tires.
