Kenworth Truck Company is the latest manufacturer to offer aftermarket Crew Cab conversions in partnership with Bentz Transport Products, a maker of aftermarket sleeper cabs. Peterbilt and Pierce Manufacturing have also worked with Bentz to build these products.           

Designed for Active Duty

Kenworth now provides an aftermarket Crew Cab conversion option for Kenworth T170, T270, and T370 medium-duty conventional models. The option is suited to the fuel, oil, fire and rescue, towing and recovery, leasing and rental markets, and utility segments. 

Tested to Federal Motor Vehicle Safety Standards (FMVSS) 207/210 occupant restraint mount and seat mount pull tests, the Peterbilt 335 Crew Cab is targeted to fire/rescue, utility/construction, and recreational markets and is available directly to Peterbilt dealers as an aftermarket modification. The Crew Cab modifications feature the same assembly method as OEM cabs, including an all-aluminum Huck-bolted cab, and maintain OEM styling, appearance, and fit-and-finish. 

Wisconsin-based Pierce Manufacturing, specializing in fire trucks, also selected Bentz as the supplier of a new special proprietary Crew Cab for fire apparatus applications. 

Interior Space Increased

Crew Cab modifications allow up to 61 inches of interior height, with a 4-inch raised rear section on the Kenworth models, and 3 inches on the Peterbilt models. The Pierce Crew Cab option is slightly larger: 56 inches in length, 98 inches wide, and 164.25 inches bumper to back of cab (BBC). 

With 157-inch BBC, the remaining structure of Kenworth's Crew Cab is aluminum, provides an additional 52 inches of length, and is 84 inches wide at the rear. Similar in length and width, Peterbilt created a 160-inch BBC with generous legroom and accommodations for three additional passengers. A continuous 3-inch raised roofline creates 61 inches of interior height from front to back. Incremental weight is approximately 900 lbs., excluding seating and option selections.
