1966 - 77 FORD BRONCO
PREMIUM CHASSIS
Built for the Early Bronco,
uncompromised for the modern driver.
The 1966-77 Ford Bronco represents one of the most iconic short-wheelbase 4x4s ever produced. Our replacement chassis honors that legacy while delivering the stiffness, geometry, and component compatibility that modern drivetrains demand.

TECHNICAL FAQ
01 Which Ford Bronco years fit the Rolling 40 chassis?
02 Will my original Bronco body bolt on without modification?
03 Which engines and transmissions is the chassis compatible with?
The chassis accepts modern V8 platforms including the Ford 5.0L Coyote, GM LT Series, Small Block Ford, and Ford 7.3L Godzilla. This is a meaningful departure from the factory Bronco’s drivetrain options. Our Universal Motor Mount Kit covers over twenty configurations, and tunnel geometry accepts modern automatics along with manual swap conversions.
04 What tire sizes can I run with each fender option?
Standard fender flares are optimized for 33-inch to 35-inch tires on factory-width or mildly offset wheels. The Exclusive 5-inch Wide Stance flares are engineered for 37-inch-plus tires with aggressive offset, with the widened track geometry already built into the chassis. Final fitment depends on wheel offset, backspacing, and ride height, which we confirm with you on your engineering review call.
05 What's the typical lead time from deposit to delivery?
Lead time depends on configuration and current production slot availability. Your Rolling 40 specialist confirms a specific delivery window during your engineering review call, once your build sheet is finalized and your deposit is in. We set production expectations up front, so you will not be chasing updates after you commit.
06 Do I need a specialized shop to install this, or can my local builder handle it?
Any competent restoration or custom 4×4 shop can mount a body onto the Rolling 40 chassis. The install is mechanically simpler than a traditional frame-off restoration because there is no frame prep, no rust repair, and no mount relocation. For engine and drivetrain integration, we recommend a shop with modern EFI and Coyote or LT-swap experience. We are happy to refer builders in your region during your review call.
