Used Nissan 350Z Steering Box

No — the 350Z uses a rack-and-pinion steering system, not a steering box. A steering box is a recirculating-ball unit typically found on older or truck-based vehicles, and was never fitted to any variant of the 350Z. If your steering is heavy, notchy, or leaking, the part you are most likely looking for is the steering rack, which is the correct term for the unit on this car.

The component you need is called a steering rack (or power steering rack, as all UK-market 350Zs came with power assistance). This is a rack-and-pinion assembly, quite different from a steering box. When contacting a breaker, ask specifically for the steering rack to make sure you receive the correct part.

The 350Z ran from 2002 to 2009, with a facelift arriving for the 2006 model year. Whether the pre-facelift and post-facelift steering racks interchange directly is not something that can be guaranteed here — confirm compatibility with the breaker against your specific registration before purchasing.

Trim level does not affect the steering rack fitment on the 350Z — the rack is common across GT, GT4, and other UK-market trim designations. What matters more is the model year and whether any mid-life changes were made to the steering assembly, so give the breaker your registration to confirm the exact unit required.

All UK-market 350Zs used the same 3.5-litre V6 engine, so engine size is not a variable you need to account for when sourcing a steering rack for this model. Simply confirm the model year with your breaker, as that is the most relevant factor for identifying the correct rack.
