Caravan and Boat Rear Galvanised Spare Wheel Carrier Stub
This Galvanised Spare Wheel Carrier is a heavy-duty, bolt-on solution designed to safely mount your spare tyre to the rear bumper or drawbar of your caravan or boat trailer.
Featuring a threaded stub axle, this carrier lets you secure your spare wheel with a standard hub-and-nut setup, ensuring it stays rock-solid even on corrugated outback roads.
Product Overview
Don’t risk being stranded with a flat and no way to carry a spare. This carrier is built from structural-grade steel and hot-dipped galvanised for ultimate corrosion resistance. The integrated stub axle is designed to accept a standard trailer hub, making it compatible with a wide range of stud patterns, including Ford, Holden, and Land Cruiser.
Key Features
- Threaded Stub Axle Design: Unlike cheap bracket carriers, this unit uses a genuine threaded stub. You simply slide a spare hub onto the shaft and secure it with a castle nut and split pin for total security.
- Hot-Dipped Galvanised: Engineered for the marine environment. The thick zinc coating prevents rust even when exposed to salt spray and constant outdoor storage.
- Universal Mounting: Designed to bolt directly onto square bumpers (RHS) or trailer drawbars. The heavy-duty base plate provides maximum surface contact to prevent “pivot fatigue.”
- Multi-Bearing Compatibility: Available in various spindle profiles to match your trailer’s existing wheels:
- Holden (LM) / Ford (Slimline): Perfect for standard utility and boat trailers.
- Parallel / Dexter 1.6t: For heavy-duty 1.6-tonne setups.
- 2T (2-Tonne): Extra-thick spindle for large caravans and heavy plant trailers.
Technical Specifications

Why Use a Hub-Style Carrier?
Standard “U-bolt” carriers can vibrate loose, damaging your wheel’s mounting holes. By using a threaded stub axle and a hub, the wheel is supported exactly as it is on the axle, protecting your rim and ensuring it is ready for immediate use in an emergency.
