Used or reconditioned?
Used S55 units are available from accident‑damaged or high‑mileage donor cars, though supply is limited compared to mainstream engines. Reconditioned units are strongly recommended for performance vehicles, as the rebuild addresses known crank hub and bearing wear points. Consider your budget, intended use, and how long you plan to keep the vehicle — reconditioned units offer factory‑spec reliability with all wear items replaced, while used units provide a cost‑effective replacement for lower‑budget builds or track‑focused projects. S55 engines are known for crank hub spin issues, particularly on modified or high‑mileage examples, which can cause catastrophic timing failure. Replacement demand is driven by this known weakness and the high cost of in‑vehicle repair. Every unit we supply has the crank hub inspected and, where necessary, upgraded to a keyed design before dispatch.
