What Is A Frame Rail On A Car

A frame rail is the main structural element of a car’s frame. The frame rails are the long vertical (or nearly vertical) beams that run along the sides of the car from the front to the back. The frame rails are usually made of steel and they support the car’s engine transmission and suspension.

The frame rails are also one of the main places where the car’s body is attached. On most cars the body is bolted or welded to the frame rails. This connection is important because it helps to stiffen the car’s body and prevent it from flexing too much.

There are a few different types of frame rails but the most common are the “ladder” type and the “box” type. The ladder type is the older of the two and it gets its name from the fact that the frame rails look like a ladder when viewed from the side. The box type is newer and it gets its name from the fact that the frame rails form a box around the car’s engine and transmission.

The main advantage of the ladder type is that it’s very strong and stiff. The main advantage of the box type is that it’s easier to manufacture than the ladder type.
