Description
The BMW N52, N54, N55, and S55 engines are known for unpredictable serpentine belt failures. When the belt fails, it can wrap around the crankshaft, bypassing the OEM crank seal and entering engine internals. This shredded belt debris can clog the oil pickup, leading to severe engine damage or catastrophic failure.
The 034Motorsport Billet Crank Seal Belt Guard is engineered to protect your engine by installing directly over the OEM crank seal to prevent a failed serpentine belt from entering the engine. Crafted from durable 6061-T6 billet aluminum and finished with a corrosion-resistant black anodized coating, this belt guard offers both superior protection and a sleek look.
Features:
-
Prevents premature serpentine belt failure debris from contaminating your oil pan, avoiding oil starvation and engine failure
-
Precision-machined from 6061-T6 billet aluminum for strength and reliability

Anodized black finish protects against corrosion and maintains a high-quality appearance
