Vocational Work Trucks

Steering Conversions

Our steering conversion allows the truck to be operated from the left or right side of the vehicle to improve visibility with curb-side operations. All controls to operate the truck are relocated to a centralized location for easy access. The applications for this modification include street sweeping, refuse, leaf and debris removal, highway paint striping, and pesticide spraying.

Cab Modifications

We provide cab modifications that maintain the structural integrity of the cab while achieving the original factory aesthetics. These modifications include the Narrow Cab and Raised Roof modification.

OEM Ship-Thru

Our modification centers are strategically located near leading car and truck manufacturing facilities, supporting ultimate customer convenience and smooth ship-thru arrangements, especially when conversions are performed on brand new vehicles.

Adding a driving front axle is a frequent option of trucks that travel off road.  And, additional axles may be specified to improve the load capacities of many chassis.  They may be mounted in front of, or behind, the drive axles.  A full range of lift and steerable versions are available.
