Extended Cab Modification for Kenworth
Part / Model: KWT270CC/T370EC

Koester's offers an extended cab for Kenworth T370/T270 medium duty trucks available directly to Kenworth dealers as an aftermarket cab modification. Designed and manufactured by Koester's, a leading manufacturer of aftermarket sleeper cabs, the T300 extended cab is targeted to vocational markets including wrecker, fire/rescue and utility/construction.
The 52" long and 84" wide integrated crew cab modification follows the rearward taper of the 270/370 cab, creating a 161 BBC with generous accommodations for three additional passengers. A 4" raised rear roofline creates additional room for headgear. Incremental weight is approximately 840 pounds plus option selections.

Koester's uses a one-piece fiberglass roof and Kenworth parts including rear door assemblies, rear corner panels, floor mat, interior lighting and grab handles. The end result is an aftermarket crew cab modification with OEM styling, appearance and fit and finish.
