Description
Bed Floor Assembly - 4 Inch Wider Tubs - 73-87 Chevy GMC C/K Short Bed Fleetside Pickup
Reproduction bed floor assembly for the 1973-87 Chevrolet / GMC C/K Squarebody Short Bed Fleetside model trucks with accommodation for 4" wider wheel tubs. (Wheel Tubs Sold Separately - See Related Items Below)
Stamped from high quality heavy gauge steel, each bed floor assembly comes complete with cross sills, tail panel and reinforcements already attached. Made on all new tools with a one-piece OE correct bed floor skin and provisions to directly bolt in our 4" wider tubs. This floor will not work with the factory width wheel tubs. Arrives EDP coated to help protect against rust and corrosion prior to installation.
With this 4" wider tub bed floor, you will save significant labor over modifying a factory spec floor to accommodate wider tubs — reducing fabrication time and delivering a cleaner OE appearance overall.

Installation
The floor arrives with the cross sills, tail panel and reinforcements already attached, and our 4" wider tubs bolt directly to it, so there is no fabricating a factory floor to make room.
Check what tubs you are running before you start. Factory width wheel tubs will not work with this floor.

Common questions
How do I know it fits my truck?
This part is listed for 1973–1986 Chevy and GMC Blazer, C10, C1500, C20, C2500, C30 and others. The full year, make and model list is in the Truck Compatibility tab on this page. If your truck has been modified, or you are between two of the year ranges we list, send us the year, make and model and we will confirm the fit before you order rather than after.
What if it is not right for the truck?
You have 30 days from delivery to request a return. The part needs to come back new, uninstalled and in its original packaging - once a part has been trimmed or welded it cannot go back. Return shipping is at your cost, and we ask that returns come by Canada Post. Made-to-order, sale and clearance items are final sale. The full terms are on our returns page.
Can I install this myself?
It is designed for an at-home install. Read the fitment notes and the Installation tab on this page before you start for anything that needs drilling, trimming or welding, and where an installation guide or video exists for the part it is linked there.
