Cab Configuration

Need help figuring out which cab configuration your truck has?

When purchasing sidesteps for your truck, it is important to know what cab size your truck has to get that perfect fit you are looking for. There are three general cab sizes but it varies on your specific make, model, and the year or generation of that model.


Regular/Single Cabs or "Standard Cabs" have two doors and no back seat for passengers. These are the smallest of all of the cab sizes. Our side steps for these cabs have one step pad per side.

Extended Cabs have a back seat and extra rear doors that usually open in the opposite direction (also known as "suicide" style). However, many truck manufacturers are making these rear doors open like the front doors and are adding door handles to the rear doors as well. For cabs of this type, the rear doors are not as big as the front doors.

Crew Cabs also have rear doors and a larger back seat than Extended Cabs. The rear doors open in the same direction as the front doors, but the rear doors are still usually smaller than the front doors, but noticeably larger than Extended Cab rear doors.

Mega Cabs are from RAM and are slightly larger than the traditional Crew Cab.
