Details
Maximum Ground Clearance and Larger Tire Capability Without Sacrificing Drivability
Turn Offroad Bronco Portal Axles deliver true clearance at the wheel hub instead of chasing height with suspension alone, giving you real capability without altering the suspension geometry Ford spent years engineering.
True Clearance at the Axle
Portals add approximately 4.75 inches of ground clearance at the axle. Since the lift happens at the hub instead of the suspension, you keep factory geometry, a low center of gravity, and the ride quality that makes portals worth the investment over a suspension-only lift.
Integrated Gear Reduction
An 11% gear reduction inside the portal delivers more usable torque at the wheel, less stress on your drivetrain, and a balance of road-friendly drivability and off-road performance built for tires up to 40 inches.
4-Gear Portal Box Design
Load spreads more evenly through the box than a standard 3-gear design, improving durability under extreme and repeated load.
Serious Materials, Serious Mounting
CNC-machined 7075 aluminum housings pair with hardened 8620 steel gears for long-term strength under real use. Steel thread inserts at every mounting location hold proper torque over time, a feature most competitors reserve for race-only portal setups.
66% More Oil Capacity
Increased oil capacity (16.9 oz) means greater thermal stability, longer service intervals, and fewer oil changes over the life of the system, with an easy-access drain and fill and a double-seal system engineered to stay leak-free.
Full System Compatibility
Retains factory ABS and parking brake function and integrates with OEM systems without compromising functionality. J-hook front rotors improve stopping power, and brake line and electrical extensions are included.
Ready to Install
Delivered as a complete system: front and rear portal assemblies, axle shafts, extensions, brake line extensions, breather and hose, manifold and fittings, wiring extensions for the electric parking brake, inner axle seals, portal windows, front axle nuts, rear installation hardware, and the 30mm socket and 10mm allen needed for install.
Fitment
Fits 2021-2026 Ford Bronco, 2-door and 4-door, Sasquatch or non-Sasquatch. Does NOT fit the Ford Bronco Raptor. Supports tire sizes from 37 to 40 inches depending on wheel setup. A printable wheel clearance template is available to confirm brake caliper and portal clearance for your specific wheel before ordering.

Questions
How much ground clearance do Turn Offroad Bronco Portals add?
Turn Offroad Bronco Portals add approximately 4.75 inches of ground clearance at the axle, significantly improving obstacle clearance and off-road capability.
What gear reduction do the portals provide?
The portal system provides an 11% gear reduction, helping improve low-speed control, torque delivery, and overall drivability with larger tires.
What tire sizes are these built to handle?
Turn Offroad Bronco Portals are designed to support tire sizes ranging from 37-inch to 40-inch, depending on wheel setup and intended vehicle use.
Do Bronco Portals keep factory suspension geometry?
Yes, the system is engineered to retain factory suspension geometry, helping preserve on-road comfort, handling, and predictable driving characteristics.
Do they retain ABS and the factory parking brake?
Yes, Turn Offroad Bronco Portals are designed to retain factory ABS functionality and the OEM parking brake system.
What's different about the 4-gear portal box design?
The 4-gear portal box design is built for increased strength and durability. By distributing load across four gears instead of three, it reduces stress on individual components and improves long-term reliability under heavy use and off-road conditions.
What materials are used in the housings?
The portal housings are CNC-machined from 7075 aluminum and paired with hardened 8620 steel gear sets. Steel thread inserts are used in all mounting points for added durability and strength in high-load applications.
