Facts About Hot Rod Frames

By Raymond Carter


Vehicle frames can be defined as the main structure that offers support to an automobile and other components are attached to it. Almost every motor car that was manufactured before 1930 has a skeleton that is separate and independent of the rest of the body of the auto. This design has however changed over time and manufacturers opted to use unibody construction. This means the chases and bodywork are incorporated into each other.

However, hot rods still feature a frame that is separate from their bodies. As such, it is one of the things that make them unique. Having a separate frame allows for placement of large engines. Larger engines in turn allow for greater linear speeds. Also, hot rod frames support other mechanical components of the vehicle besides the body. Hotrods have stronger frames that enable them to deal with the dynamic and static loads without having any undue distortion or deflection.

There are several dynamic and static loads that the frame of a hotrod deals with such as the cargo weight. Others include the torsional and vertical twisting motion resulting from the motor vehicle going over surfaces that are uneven. As most hotrods are designed for speed, they must have a chassis that can withstand the transverse lateral forces resulting from the conditions of the road.

Side winds and automobile steering motion may also bring about traversal lateral forces. The frame design must allow it withstand collisions and the sudden resultant impacts. There are a number of things to consider in frame construction for hotrods. These include, starting, longitudinal tensile forces due to acceleration, and torque due to engine transmission.

Hotrod frames are mostly constructed using ladder type frame. Up to now, it is the simplest and oldest of all types of frames. Typical ladder frame has two channels, that is, trails or beams that have symmetry. The two are joined by transverse cross-members and run the whole length of the car. The cross-members are installed after specific intervals as considered fit. Similar to all other frame designs, it has its merits and demerits.

Its ability to offer good beam resistance is one of its advantages. This advantage is realized due to the continuous rails running from the rear to front. On the other hand, its resistance to warping or torsion is quite poor especially if the cross-members used are simple or of poor quality. The other thing that a person constructing a ladder frame has to deal with is the overall height of the vehicle.

In general, the height of vehicles with ladder type frame seem to be more. The cause of these is the fact that floor pans have to be included on the frames. Actually, floor pans sit over the frame instead of sitting inside it. Luckily, the issue can be easily addressed before the job starts since hotrod frame is normally custom built.

To conclude, a person must have their chassis produced by the best for safety reasons. Normally, experienced chassis producers are the best at this are they are better positioned to include the specifications that a person wants. It is the experience coupled with innovation that makes this possible. As hot rods are unique, a person must ensure that the uniqueness is also captured in their chassis.
