BMW S55 Crankshaft Repair Service - F80 M3

Our S55 crankshaft repair can turn your spun rod bearing S55 crankshaft back into a good usable crankshaft. We grind down the damaged journals and weld them back up. We then grind the crankshaft back to its original dimensions. The crankshaft is then heat treated and micro polished.

Most crankshafts can be repaired, for severely damaged crankshafts that have multiple spun bearings or damage to a guide bearing journal costs may be higher than listed. In general this pricing includes repairing one journal. Each additional journal will add $175 to this price. If additional repair costs are required we will advise you before we begin the repair. We can usually return repaired crankshafts in about 4 weeks. In most cases we have repaired cores in stock that can ship immediately. Call us for current stock levels.

As with any bottom end assembly we highly recommend checking main, rod, and thrust bearing clearance as you assemble.

To move forward with the repair service please add this product to your cart and checkout. You will select and pay for the shipping service for us sending your crankshaft back to you. Take your invoice, print it out and package your crankshaft with it. We suggest a double wall cardboard box to avoid shipping damage. You will need to arrange shipping from your end to get your product to our shop address:
