What Cab Does My Truck Have?

The Main Cab Configurations

Most pickups use body-on-frame construction, with the cab and bed mounted to a separate ladder-style frame. These trucks generally come in three cab configurations: Regular Cab, Extended Cab, and Crew Cab. Some configurations, such as Ram’s Mega Cab, provide additional space beyond a conventional Crew Cab. 

Regular Cab

The Regular Cab is the traditional "work truck" layout. 

Features:

• Two doors
• One row of seating, often a bench seat
• Seats 2–3 passengers
• Minimal interior storage space

These cabs are common on fleet vehicles, work trucks, and older pickups where cargo capacity is prioritized over passenger space.

Extended Cab

The Extended Cab was designed to provide additional interior storage and occasional rear seating without the size of a full Crew Cab.

Features:

• Front doors with smaller rear doors on some models
• Small rear seating area on some models
• Additional storage behind front seats
• Often a shorter overall wheelbase than a Crew Cab

Extended Cabs are extremely common on trucks from the 1990s through the early 2010s. The challenge is that almost every manufacturer gave this cab style a different name.

Crew Cab

The Crew Cab provides full-size rear seating and four full-size doors.

Features:

• Four conventional doors
• Full rear bench seating
• Full-size rear passenger area
• Most popular truck configuration today

Modern Crew Cabs often serve as family vehicles, daily drivers, and tow rigs.

Why Cab Configuration Matters

Cab configuration can affect the truck’s wheelbase, frame length, cab mount locations, crossmembers, and which section of the frame our repair kits fit. 

A 2005 Chevrolet Silverado Regular Cab frame can differ significantly from an Extended Cab frame of the same year. Before ordering any frame repair components, it's important to correctly identify your truck's cab style.

Manufacturer Cab Naming Guide

Names vary, but most manufacturers are describing one of three cab configurations.

FORD "SUPERCAB"
Ford uses the SuperCab name for its extended-cab configuration. Depending on the model and model year, SuperCab trucks have been offered with two, three, or four doors. The rear doors on four-door versions are smaller than the front doors and may be rear-hinged depending on the generation.

DODGE/RAM "MEGA CAB"
Available only on heavy-duty 2500 and 3500 trucks, the Mega Cab has four full-size doors. The difference between it and a Crew Cab? The Mega Cab has additional cab space behind the rear seats, providing more passenger room and interior storage.

TOYOTA "ACCESS CAB/DOUBLE CAB/XTRA CAB"
Toyota's cab names vary by model and generation. Toyota used the XtraCab name on its compact pickups throughout the 1980s and 1990s, and later on early Tacoma models, to identify an extended-cab configuration with additional space behind the front seats. Tacoma later used Access Cab for its extended-cab configuration, while Double Cab is a four-door crew-style configuration. Beginning with the 2024 Tacoma, Toyota brought back the XtraCab name for a two-door, two-seat configuration with additional storage space behind the front seats. On Tundra, Double Cab has two full-size front doors and two smaller, forward-hinged rear doors, while CrewMax has four full-size doors and a larger rear passenger area.

CHEVY/GMC "DOUBLE CAB"
Beginning with the 2014 model year, General Motors changed the Extended Cab configuration moniker on the Silverado and Sierra 1500 to Double Cab. These trucks use front-hinged rear doors rather than the rear-hinged rear doors found on previous Extended Cab models. The Colorado and Canyon continue to use the Extended Cab name.
