CNC Mandrel Bent Early Bronco Frames
Our Early Bronco frames are made by Kincer Chassis where form and function are combined.
The custom Early Bronco chassis is the ultimate in aftermarket performance for 1966-77 Broncos.
Mandrel bent 2x4 rails
The rails are 2x4 rectangular tube with a 3/16” (.188) wall, CNC mandrel bent to shape. Heavier rails are what keep an Early Bronco frame from flexing.
Bolts to your factory body
Body, bumper and suspension mounts sit in the factory locations, so your original Bronco body and bumpers go right back on. Mounts can be moved for a different suspension setup.
2” more room inside
Measured inside to inside, the frame rails are 2” wider than stock. That space is there for modern drivetrains.
Ready for your swap
There’s room for a Coyote 5.0, 351W or 4BT diesel, long tube headers and a clocked Atlas transfer case.

How This Early Bronco Chassis Will Make a Difference in Your Daily Drive
Designed for exceptional performance on both urban streets and rugged off-road trails, Kincer Chassis' custom 4-link coil-over rolling chassis for the Early Bronco includes a suspension system that ensures unparalleled ride quality and handling for the early Bronco. This advanced system gives you a smooth, comfortable ride over a variety of terrains while maintaining precise control and responsiveness.
You get behind the wheel of a Bronco with one of their chassis and you truly will understand the difference it makes!

Fabricated axles and sway bars
Included as standard options are Kincer Chassis' meticulously fabricated axles. These high-strength axles are engineered for superior durability and optimal performance, ensuring your Bronco can tackle any trail with confidence.
The axles pair perfectly with their front and rear sway bars, specifically designed for maximum stability and balance. This combination not only enhances the Bronco's ability to navigate challenging terrains but also improves handling on the interstate and during high-speed cornering and unexpected maneuvers.
Settled at interstate speed
If you've driven an Early Bronco before you know how it feels when you get up to speed on the interstate. This makes it where it doesn't feel like that and that's a big deal.
If you have a family, it can feel like an even bigger deal!
Wilwood disc brakes
To further bolster the performance of your early Bronco, Kincer Chassis also integrates Wilwood disc brakes as a standard feature.
Celebrated for their reliability and superior stopping power, these high-quality brakes ensure prompt, secure stopping, which is essential for both city driving and off-roading or overlanding in your Classic Bronco.
Powder coated and fully assembled
Kincer Chassis provides powder-coated coil-over rolling chassis as fully assembled. This state-of-the-art design not only simplifies the installation process but also ensures maximum resistance to corrosion and long-term durability.
The robust and beautiful finish enhances the look of your Bronco while providing an additional layer of protection against the elements.
What owners say about their Kincer chassis
★★★★★
Not only did Kincer Chassis build an incredible rolling chassis for us, complete with powertrain, they have been instrumental in helping with every other aspect of the build. Their experience and advice has saved me a lot of mistakes and helped build a better Bronco than I could have imagined. Great people and even better products or is it great products and even better people – hard to say…
★★★★★
I cannot say enough about Kincer Chassis. Thomas and his crew took the time to explain the process to me and were extremely thorough. They worked seamlessly with my restoration guy up in Michigan to produce a perfect rolling chassis for my ’71 Bronco. I couldn’t be more pleased–the truck looks great, my new Coyote engine fits perfectly and (best of all) I know I have a safe new frame for my family and me.
In conclusion, Kincer Chassis' custom-built rolling chassis package offers outstanding performance and durability for the early Bronco and we're proud they are using our Krawlers Edge Early Bronco components and parts. Whether you're cruising city streets or exploring off-road trails, this setup is designed to elevate your driving experience.

Ask us a questionHow much does a Kincer Early Bronco chassis cost?
Kincer Chassis lists its custom Early Bronco frame starting at $3,999.99. A complete rolling chassis costs more because it adds the suspension, axles, sway bars and Wilwood brakes, and the final price depends on the series and options you choose. Tell us about your build and we’ll get you a quote.
Which Broncos does this chassis fit?
It’s built for every first generation Ford Bronco: 1966, 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976 and 1977. The frame uses the factory body, bumper and suspension mount locations, so your original Bronco body goes back on it.
Will a Coyote swap fit in this chassis?
Yes. The frame rails are 2” wider than stock, inside to inside, which leaves room for a Ford 5.0L Coyote with long tube headers and a clocked Atlas transfer case. Kincer also lists the 3.5L EcoBoost, 351W, Cummins R2.8 Turbo Diesel and 4BT. We make the Coyote swap parts to go with it.
Can I buy it as a complete rolling chassis?
Yes. Kincer Chassis builds it as a fully assembled, powder coated coil-over rolling chassis, with fabricated axles, front and rear sway bars and Wilwood disc brakes as standard. The Coil-Over, Classic and Builder options are shown above.
Is a Kincer chassis worth the investment?
If your Bronco is going to see the interstate, the trails or your family in the back seat, the chassis is where you feel the difference. The heavier mandrel bent rails take out the flex, and the coil-over suspension, sway bars and Wilwood brakes keep it steady at highway speed. It also bolts to your factory body, so you keep your original Bronco.
Does the frame come with a VIN?
No. Each frame has a Kincer Chassis (KC) number welded into the driver’s side engine perch. That KC number is tied to your purchase record and to the serial number on your Ford Security Tag for licensing.
Who builds the chassis?
Kincer Chassis builds it at 3707 Louisville Road in Louisville, Tennessee, the same address as Krawlers Edge. Both companies are part of the Kincer family.
