The CBC full width diffuser fits 67-72 fleetside, short box C10’s. It is a modular design, allowing custom spacing or replacement of the fins. This kit comes complete with roll pan and all mounting hardware and brackets. These do not work with a rear mounted fuel tank that hangs below the frame rails. Some modification of the lower wheel well is required.

Note: These are custom built to order, so expect a 6-8 week lead time.
