For years, contractors have leaned on the Knapheide Drop Side Contractor Body to handle the heavy-duty jobs. Knapheide's Drop Side Contractor Bodies have everything a contractor needs including drop sides with cheater boards for increased load capacity, a double-acting tailgate for both drop down and spreader applications, behind the cab trip lever for quick access to dumping operation and an aerodynamic tapered bulkhead for improved visibility. Standard body lengths stretch from 12' up to 18' for one ton up to medium-duty chassis. Carry up to six cubic yards of bulk material in one load with a Drop Side Contractor Body.
