King Series Cab Kits
Ready to build your own 6-door Ford Super Duty?
King Series 6-Door Cab Kits make it possible. Our 2017–2026 Ford Super Duty cab kits include everything you need to create a seamless, factory-quality 6-door truck — complete with precision-fit composite panels, reinforced roof, and full factory door function.
The Industry’s Most Advanced 6-Door Cab Kit
Our cab kits are designed to match OEM construction standards for 2017+ aluminum-body Ford Super Duty trucks. Instead of cutting and filling, we use a structural weld-and-replace process to deliver factory-grade fitment and strength.
Outer roof and side panels are removed for precision welding
The structure is reinforced internally
Custom King Series composite panels are installed for a perfect finish
This is the same proven process we use on our in-house builds, giving your DIY or shop-built project true factory alignment and durability.
The First One-Piece Door and Roof System
When Ford introduced the aluminum body in 2017, traditional builders could no longer reuse rear doors as middle doors. We solved that.
Custom One-Piece Composite Doors
Our patent-pending middle doors feature carbon fiber reinforcement, zero body filler, and seamless body lines. They’re compatible with factory glass, hinges, and internal mechanisms — as strong or stronger than OEM.
Seamless Reinforced Roof
We engineered a one-piece reinforced composite roof that eliminates visible seams and filler work. Tested to withstand heavy impact, it sets a new standard for strength in aluminum 6-door builds.
What’s Included in Every Cab Kit
Composite side aperture panels
One-piece reinforced composite roof
Carbon fiber and Kevlar-reinforced middle doors (factory hardware compatible)
LizardSkin ceramic insulation & sound control inside cab
Sealer primer applied to the exterior shell
All structural reinforcements for proper assembly
Detailed step-by-step instructions
Each piece is precision-engineered for a factory-style appearance — no body filler or custom parts needed.
Why a Complete Kit?
Many ask, “Why not just sell the doors?”
The answer: fitment and strength.
Building a 6-door truck requires removing and reassembling the roof and side structures — and every panel must align precisely for the cab to remain structurally sound. Selling separate pieces would compromise safety, quality, and function.
Complete Kit Advantages
