2022 Ford Bronco Raptor Chassis and Drivetrain Explained

To build the world’s first Ultra4-inspired SUV, Ford Performance set the bar high. Bronco Raptor had to be even faster and bring more off-road capability, agility and maneuverability than Bronco already delivers.

Starting with the Bronco frame foundation, the Ford Performance team knew it needed a Raptor-specific version for increased suspension travel and track width for handling stability during high-speed desert runs. At the Raptor core is a fully boxed, high-strength steel frame with new shock towers that increase wheel travel and off-road durability.

Competition-level, Ford Performance-developed axles, also used on the Bronco DR race truck, further deliver on the Ultra4-inspiration. The solid rear axle is upgraded to a semi-float Dana 50 Heavy-Duty AdvanTEK with 235-millimeter ring gear, while the Dana 44 AdvanTEK front-drive unit includes upgraded half-shafts with 210-millimeter ring gear.

An advanced 4×4 system with three modes includes a higher-capacity clutch designed to withstand the demands of high-performance desert events.

The Ford Performance team collaborated with FOX to upgrade the High-Performance Off-Road Stability Suspension (HOSS) system with Live Valve technology. Similar to the F-150 Raptor truck’s position-sensitive damping design, the Raptor HOSS 4.0 system features FOX 3.1 Internal Bypass Semi-Active Dampers (3.1-inch diameter) that are uniquely tuned at the front and rear and feature integrated reservoirs up front and remote reservoirs in rear.

Unique Ford Performance-designed front and rear control arms help deliver maximum wheel travel of 13.0 inches in front and 14.0 inches at the rear, or 60% and 40% more, respectively, than a Bronco base model. To deliver the confidence and high-speed needs of the world’s first Ultra4-inspired SUV, the Ford Performance team reached out to BFGoodrich for standard 37-inch KO2 all-terrain tires.

To give Bronco Raptor even more desert-running power, the Ford powertrain team developed the proven twin-turbo 3.0-liter EcoBoost engine with specific Raptor-level tuning to meet Ford Performance standards. With a target of more than 400 horsepower.

For higher-speed desert capabilities or crawling over rocks, the compacted graphite iron-block engine, which saves weight while providing strength for added durability, is paired with a 10-speed SelectShift automatic transmission tuned to meet Ford Performance standards.

Bronco Raptor builds on the brand’s exclusive GOAT Modes (Goes Over Any Type of Terrain) Terrain Management System designed to help drivers better navigate off-road.
