Portal Lift Advantage
Clearance Where It Matters
Portals provide true axle clearance the right way—without piling on suspension height—so you keep factory geometry, a low center of gravity, and the kind of ride quality that makes portals worth it.
4.75" More Ground Clearance
Adds clearance where it matters most.
No Excessive Suspension Height
Achieve lift without stacking compromises.
Better Stance and Geometry
Keeps suspension geometry more controlled than a comparable suspension-only lift.
How it Works
The system moves torque multiplication to the wheel to help run larger tires while reducing drivetrain stress.
Gear Reduction and Drivetrain Protection
Portals multiply torque at the wheel. That helps you run larger tires while reducing load on the parts that see it first.
OEM Ratios Stay in Place
Keeps OEM gear ratios and factory engineering in place.
Reduced Drivetrain Stress
Designed to ease the load on your ring and pinion, transfer case, and driveshafts when running larger tires.
Maintain Reliability
By correcting the effects of larger tires, the rest of your Bronco continues to operate like it did from the factory.
Tire Size Correction
Helps your Bronco properly account for larger tires, including corrected speedometer function, without the hassle of traditional regearing.
Bronco Portals are for the driver who wants true clearance and larger tire capability without giving up daily drivability.

Are these Bronco Portals compatible with my 2021+ Bronco?
Turn Offroad Bronco Portals are designed for all 6th generation 2021+ Ford Broncos, including both 2-door and 4-door models (non-Raptor), sasquatch or non-sasquatch.
Will these work on the Bronco Raptor?
No, this system is specifically designed for non-Raptor Broncos and is not compatible with the Bronco Raptor.
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.
