GADFISH Stainless Steel Spare Tyre Carrier Trailer Mount — Fits 4/5/6‑Lug Wheels, 150 lb Bolt-On

GADFISH Stainless Steel Spare Tire Carrier is a universal, bolt-on trailer mount that secures 4-, 5- and 6-lug spare wheels and supports up to 150 lbs without drilling or cutting.

Built to withstand wet conditions and roadside demands, this spare tire carrier is a corrosion-resistant stainless steel bracket that installs quickly on most trailer frames. Its welded triangular supports and rectangular backing plate bring rigidity and stability, while the sloped design minimizes wind drag and keeps the spare close to the trailer for safer towing. The carrier is compatible with common bolt patterns and includes multiple-length bolts so you can choose the installation height that fits your trailer beam.

What lug patterns and wheel sizes does this mount accept?

The GADFISH carrier works with widely used trailer wheel configurations, accommodating 4-, 5- and 6-lug hubs across several bolt circle diameters. It was designed to cover a broad range of trailer and boat setups so you won’t need multiple mounts for different wheels.

• 4-lug: 4.00" bolt pattern
• 5-lug: 4.50", 4.75", and 5.00" bolt patterns
• 6-lug: 5.50" bolt pattern
• Rated to support spares up to 150 lbs

How does installation work and what tools are required?

Installation is a bolt-on process designed for convenience—no cutting, welding, or drilling into the trailer frame is required. The kit includes bolts of different lengths so you can set the carrier at the height you prefer; a standard wrench or socket set is all that’s needed.

• Bolt-on design—attaches directly to trailer steel beam
• Multiple-length bolts included for height adjustments
• Only basic hand tools required (wrench or socket)
• Fast installation and straightforward removal when needed

How does the carrier stand up to weather, vibration, and road use?

Constructed from stainless steel and reinforced with welded triangular and back-plate supports, the mount resists rust and deformation in wet, coastal, or roadside conditions. The raised sloping profile reduces wind resistance and keeps the tire tightly secured once fasteners are torqued.

• Stainless steel resists corrosion and staining
• Triangular welded reinforcement for added rigidity
• Low-clearance, raised slope design reduces drag
• Secure clamping after bolts are tightened to prevent loosening

What does GADFISH provide for warranty and support?

Who is this for: This spare tire carrier is ideal for trailer owners, boat trailer users, and tradespeople who need a durable, corrosion-resistant mounting solution that fits multiple wheel lug patterns.
