ALPHA COMPETITION BMW S55 Crank Hub Capture Plate M3 F80 / M4 F8X / M2 COMPETITION F87

Crank hub failure is one of the most serious and feared issues affecting the S55 engines found in the BMW M3 F80, M4 F8x, and M2 Competition. While it can occur on stock engines, the risk increases considerably with tuned engines. One of the most cost-effective and straightforward solutions to minimise this risk is the installation of the Alpha Competition crank hub capture plate.

This plate is designed to securely hold the crank hub bolt in place, helping to prevent it from loosening — a failure that could lead to pulley damage and severe mechanical issues. A major advantage is that installation does not require engine removal.

Key features:

• Direct-fit installation with included hardware

• Quick and easy to install without engine removal

• Made from high-quality 6061 aluminium

• Durable black finish

• Lifetime warranty
