GADFISH Spare Tire Carrier for Trailer & Boat — Universal 4/5/6‑Lug, 150 lb Heavy‑Duty

GADFISH Spare Tire Carrier is a heavy-duty trailer and boat spare-mount bracket that secures wheel spares with a reinforced triangular frame and holds up to 150 lbs.

Keep a ready spare on your trailer or boat trailer with a mount built to endure road vibration, saltwater spray, and frequent use. This universal carrier accommodates common 4-, 5-, and 6-lug bolt patterns and offers a sandblasted, powder-ready finish so it resists corrosion and looks tidy on the tongue or frame of the trailer.

How does this carrier fit different wheel bolt patterns?

The GADFISH carrier is engineered for broad compatibility with multiple lug configurations so you can use one mount for many trailers. It supports 4-lug (4"), 5-lug (4.5", 4.75", 5"), and 6-lug (5.5") hole patterns without special adapters.

• Fits 4-lug wheels with a 4" bolt-circle diameter.
• Fits 5-lug wheels with 4.5", 4.75", and 5" diameters.
• Fits 6-lug wheels with a 5.5" bolt-circle diameter.
• No drilling or custom machining required for these common patterns.

How strong and durable is the mount for on-road towing or marine use?

This spare tire bracket uses a welded triangular reinforcement and a rectangular backing plate to transfer load into the trailer beam. Solid iron construction plus a sandblasted surface produce a rugged part that resists fatigue and handles up to 150 pounds of tire weight.

• 150 lb rated capacity for most trailer spares and small wheels.
• Welded triangular brace reduces flex and vibration under load.
• Sandblasted finish removes impurities and improves corrosion resistance.
• Heavy-gauge iron resists bending on rough roads and in marine environments.

Is installation difficult and will it require special tools or drilling?

Installation is straightforward and designed for common hand tools; no drilling is generally necessary. The kit includes multiple bolt lengths so you can secure the mount to varying beam heights and choose the steel beam height that best fits your trailer layout.

• Comes with assorted bolt lengths for different frame thicknesses.
• Sloped, low-profile design reduces wind drag and keeps clearance low.
• No drilling required on most trailer beams—install with a wrench.
• Lock-holder design helps prevent accidental wheel loss once torqued.
