Prevent one of the most common and costly N55 engine failures with this heavy-duty billet aluminum power steering pulley upgrade. Designed to replace the weak factory plastic pulley, this upgraded solution protects your serpentine belt system and helps eliminate the risk of sudden belt loss or engine damage.

On many N55 applications, the factory plastic power steering pulley is prone to cracking or contacting the subframe under load. When this happens, the belt can derail—leaving you without power steering and, in severe cases, allowing the belt to be pulled into the engine. This billet aluminum pulley is engineered to permanently solve that issue.
