Engineered specifically for fabricators, custom shops, hot rod builders, and serious enthusiasts, these heavy-duty wheel tubs provide the foundation you need for today’s extreme wheel and tire setups.

Whether you’re fitting deep-lip wheels, running oversized tires, swapping axles, or lowering your vehicle with air ride or coil-overs, these oversized wheel tubs give you the space and flexibility required to build with confidence. Made from premium 16-gauge steel and designed to be trimmed, shaped, and welded to your exact specifications, each pair of wheel tubs offers unmatched strength and adaptability.

With generous dimensions of 36 inches wide × 20 inches tall × 13 inches deep, these tubs offer expanded clearance for wheel travel, articulation, compression, and aggressive stance setups. Side panels make fabrication cleaner and faster, helping builders create seamless transitions and professional-grade results.

Key Features of the Extra Wide 36" Wheel Tubs With Side Panels (Pair)

Heavy-Duty 16-Gauge Steel for Maximum Strength

These wheel tubs use strong, rigid, weld-friendly 16-gauge steel — preferred by professional fabricators for its durability and stability during welding and bodywork. Unlike thin, overseas-made sheet metal that warps or flexes, this steel provides a reliable foundation for serious builds.

Oversized 36" Width for Better Fitment Flexibility

The exceptionally large 36-inch width gives you plenty of room to trim and shape the wheel tubs to your vehicle’s contours. This oversized format is ideal for:

• Mini-tub conversions

• Bed tubbing in trucks

• Pro-touring muscle cars

• Custom frame modifications

• Air ride suspension builds

• Deep-lip wheel setups

• Wide tire applications

• Drag racing clearance

20" Height and 13" Depth for Serious Tire Clearance

Whether you're running tall tires, wide tires, or deeply offset wheels, the 20" height and 13" depth make these tubs perfect for:

• Full suspension compression

• Air-ride "aired out" stance

• Coil-over travel

• Drag slicks and radials

• Custom-width axle builds

Side Panels for Cleaner Installation

Side panels eliminate the need to hand-fabricate transition pieces and save valuable build time. They help create a smooth, sealed, and strong connection between the wheel tub and surrounding sheet metal.

Sold as a Matching Pair

Each set includes two matching wheel tubs and side panels, ensuring a consistent finish and professional appearance on both sides of your vehicle.

Why Builders Choose Extra Wide Wheel Tubs: Real-World Applications

1. Mini-Tub Conversions on Classic Cars

Camaro, Chevelle, Mustang, Nova, Challenger — classic muscle cars need more space to accommodate bigger wheels and modern suspension systems. These tubs allow significantly wider tires without destroying factory sheet metal beyond necessity.

2. Custom Trucks & Bed Tubs

For bagged full-size trucks, custom show trucks, and body-dropped builds, wheel tubs like these are essential. The 36" width gives fabricators enough material to shape around bed floors, notch covers, and custom inner fenders.

3. Hot Rods, Rat Rods & Custom Classics

Builders upgrading from narrow factory wheel housings to wider, safer, cleaner sheet metal find these tubs perfect for fabrication-heavy projects.

4. Air-Ride Suspension Vehicles

Aired-out rides need maximum clearance so the wheels can tuck cleanly without rubbing. These tubs provide the additional space needed for compression travel.

5. Drag Racing & High-Horsepower Builds

Wide slicks, drag radials, and modern performance tires require clearance. Mini-tubbing with these oversized wheel tubs helps maximize traction and stability.

6. Custom Chassis & Fabrication Projects

For builders designing one-off chassis setups, widening track width, or altering axle geometry, the open format of these steel tubs is ideal.

Fitment & Installation Notes

Because each custom build has many variables, it's important to read the following carefully:

Fitment Variables

We cannot guarantee that these tubs will fit any specific vehicle out of the box. Every build differs because of:

• Tire height and width

• Wheel diameter, width, offset, and backspacing

• Vehicle make and model

• Shortened or widened axles

• Suspension travel and compression

• Body drop or frame modifications

We strongly recommend measuring your vehicle at ride height (or full drop) with wheels/tires mounted, and observing clearances before fully committing to trimming or welding the tubs into place.

Fabrication Required

These tubs are foundation components only. That means:

• You will need to cut and trim the sheet metal to fit your application.

• Welding is required to mount them properly.

• Bodywork and finishing (primer, paint, seam‐seal) is required for a final appearance.

• They are not bolt-on, drop-in solutions.

If you’re not familiar with metal fabrication, welding, and bodywork, we strongly suggest working with a professional shop.

Installation Overview (General Guide)

Although every build is different, a typical installation includes:

1. Establish Ride Height & Wheel Position

Set the vehicle at its true final ride height — particularly important for air-ride setups.

2. Remove the Factory Wheel Tubs

Cut along the OEM seams and remove all sheet metal in the way.

3. Test Fit the Wheel Tubs

Hold the tub in place to evaluate how much trimming is needed.

4. Trim to Fit

Shape the tub to match your wheel openings, bed floor, or trunk floor.

5. Weld Into Position

Use MIG or TIG welding for secure attachment.

6. Add Side Panels (If Selected)

Side panels help close gaps and create a smooth, sealed wheel well.

7. Seam Seal & Reinforce

Prevent moisture and debris from entering your trunk or bed.

8. Bodywork & Finish

Prime, paint, undercoat, or apply bedliner depending on your final design.

Why These Wheel Tubs Are a Must-Have for Modern Builds

• Allow larger tire and wheel combinations

• Prevent rubbing and body damage

• Improve suspension travel

• Support extreme stance setups

• Strengthen inner wheel well structure

• Provide more room for custom suspension geometry

• Enhance performance in drag and street builds

Modern builds push the limits—these tubs give you the clearance to do it safely and professionally.
