Choosing A Cabover Pt 2: Wheelbase

Updated: Sep 17, 2022

One of the many features to consider when choosing which truck meets your needs is wheelbase. Isuzu’s N Series cabovers come in 4 stock wheelbase options. The wheelbase of the vehicle affects both the size and center of gravity of the load placed on the chassis. Below you will find a quick reference guide for N Series trucks of different wheelbases.

*Conversion on the 109” wheelbase chassis is not being offered in summer/fall of 2022. The same systems that allow for RidgeRocks exceptionally high center-clearance, or "breakover angle", also increase the angle of attack on the rear drive shaft in shorter chassis.


Wheelbase Modification

RidgeRock offers optional chassis alterations including chassis shortening down to a 132.5” wheelbase. This can be a great option to get your final build down to your preferred overall length. Chassis modification may also include shortening frame rails or the application of auxiliary equipment.
