Platforms We Support

We design and manufacture modern chassis solutions for classic Ford and Chevy trucks, with a focus on the most popular platforms from 1947 - 1979. Each chassis is engineered specifically for its year range, not adapted or generalized, ensuring proper geometry, fitment, and long-term reliability.

Standard chassis packages are offered for 1948-79 Ford Trucks/Broncos, and 1947-87 Chevy trucks. Most packages range from $30,000 to $75,000+, depending on configuration, suspension, and drivetrain options.

Supported Drivetrain Configurations

Our chassis are engineered to integrate modern drivetrain systems that dramatically improve performance, reliability, and drivability. We support late-model Ford and GM powerplants including Coyote, Godzilla, LT1, and LT4 platforms, paired with modern automatic or manual transmissions. Each drivetrain is designed as a complete system, accounting for cooling, exhaust, fuel delivery, steering integration, and serviceability. Whether the goal is a refined daily driver or a high-performance street build, our chassis are built to support it without compromise.

Level 1 (Coilover, 1-2" Drop)

Elevate your comfort and style with our Level 1 Coilover Suspension package. Experience a smoother ride with a subtle ride height adjustment, keeping your vehicle's classic charm intact. No alterations are made, preserving the original design, ensuring a seamless fit for Revival Series editions.

(Rear wheel openings will not be modified, and therefore, any Revival Series edition on a Level 1 chassis will be limited to widths on rear wheels.)

 Level 2 (Coilover, 4-6" Drop)

Enhance with our Level 2 package, lowering the ride height and making precision modifications to the bed floor. This customization offers a sleek appearance and the option to widen rear wheel openings while retaining the choice of a wood or metal bed floor for a personalized touch. Overall stance will maintain roughly 4" to 6" of ground clearance at the rocker panel, and rear wheel openings can be modified up to 12" wide.


(All Revival Series with a level 2 ride height will be constructed with a wood bed including those model years that originally come with metal beds, which are available upon request.)

 Level 3 (Airride, Slammed)

Experience luxury and style with our Level 3 package, featuring an adjustable ride height that allows you to lay the chassis on the ground when air bags deflate for ultimate customization. Choose between wood or metal bed floors, and enjoy a lowered cruising height with a ground clearance of 4" to 5" at the rocker panel. Level 3 bed floors will also be finished with a flat panel seen when the tailgate is down.

(Bed floor modifications will be static and do not include the ability to open and close the floor. Available on request.)

 Does the chassis line up with the body? Are the cab mounts in the same location as factory?

Absolutely, the cab mounts on the chassis are in the same location as factory. They are fully bolt-on, incase your cab isn't square and the mounts need to be adjusted for perfect fitment. 

 What is the width of the rear axle?

We have options for 56" and 60" rear axles (2WD), depending on the wheels/tires you would like to use. For 4WD packages, we typically use a 66" front & rear axle.

We currently have 3 different ride height options for our 2WD frames, and 2 different ride height options for our 4WD frames:

2WD:

 What drivetrain options do you have available?

We standardly use the 5.0 Coyote (Ford), 7.3L Godzilla (Ford), LS3 (Chevy), and LT4 (Chevy). Any other drivetrain will be handled as a case-by-case basis, unless we have any historical data available.

 Are the Falcon Coilovers adjustable?

They are adjustable 1-2" coilovers, rated to 900 lbs.

 What brand of mufflers do we recommend?

We typically use Magnaflow for our 5.0 Coyote builds, but have several options available. 

 Does the frame/drivetrain include a warranty?

You bet, both the frame and drivetrain are covered by manufacturer warranty, and FFG labor warranty.

 Can you start the engine in your fully loaded chassis before it ships?

Absolutely, we can start your motor when installed in the chassis before it ships. A final tune will be required for the best drive once the build is completed.

 When supercharging a Coyote, what size pulley do you use?

We typically use a 3.75" pulley when using a 3.0L Whipple Supercharger, but have more options available based on application.

 How much of a lift does your 4WD chassis give the truck?

Our 4WD chassis typically provide a 4-6" lift from factory ride height, depending on wheel/tire selections.

 Will you sell the chassis without brakes or suspension?

You bet, we are able to sell our 2WD chassis packages without brakes or suspension, although it is recommended they are sourced from FFG for the best compatibility.
