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 a number of static and dynamic loads handled by the frame on hotrods, including cargo. Additional loads include the vertical twisting and torsional motion resulting from traversing over uneven surfaces. The road condition causes extensive lateral forces thus hotrod designs include a chassis for speed and withstanding these forces.

Transversal lateral forces can also be caused from the steering motion of the motor vehicle and side wind. The frame must be designed such that it can withstand sudden impacts from collisions. Torque from the engine transmission and longitudinal tensile forces from acceleration, compression of brakes, and starting must also be considered when constructing a frame for a hotrod.

In most cases, hot rods are constructed with the ladder type frame. Up to now, this is the design that is the simplest and the oldest. In a typical ladder type frame, there are two symmetrical channels on the frame namely trails or beams. Similar to others, they traverse the whole length of the car and they are linked by traverse cross-members. The placement of cross-members is done at intervals deemed fit. This kind of frame comes with its own advantages and disadvantages like any other.

Among its advantages is the ability to offer good resistance to beam. This is identified because of the continuous rails that run from the rare to the front. On the contrary, it has poor resistance to torsion or warping, especially when poor quality or simple cross-members are used. In addition, during construction, the overall height of the vehicle must be managed well.

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.

In conclusion, it is safer for one to hand production of their chassis to the best producer. In normal circumstances, chassis producers with experience are most suitable as they can include the specifications and specifications provided by the client. This is made possible by innovativeness and experience. Given that hot rods are usually unique in many ways, it is also important to ensure that the chassis is also unique.
