Turn Offroad 2021+ Ford Bronco Portal System - 4.75" Lift / 4 Gear 11% Reduction Front and Rear (Non Bronco Raptor)
More clearance, proper gearing, speedometer correction, and true lift—THE ONLY RIGHT WAY to do bigger tires.
Designed specifically for 6th Gen Broncos, Turn Offroad's 2021+ Ford Bronco Portal System delivers lift at the axle, reduces drivetrain stress, and preserves OEM engineering - making it the ideal solution for daily drivers that wheel hard. Unlike suspension-only lifts with larger tires, the Turn Offroad Bronco Portals provide torque reduction directly to the wheel, unlocking improved crawl ratios while reducing load on critical drivetrain components. The result is a smoother, stronger, longer-lasting system built for real-world abuse and long highway miles alike. Every detail - from material choice to sealing, lubrication, braking, and serviceability has been obsessively engineered to create a Bronco Portal axle that performs on the trail and behaves on the street for smooth driveability. This is not just a lift ... It’s a full drivetrain upgrade that brings maximum ground clearance & larger tire capability to Ford Bronco owners without sacrificing daily drivability or reliability.
Features
- True Clearance: Portals give you clearance and 4.75" of lift at the wheel hub instead of chasing height with suspension. That means more capability without altering the suspension geometry that OEM’s spend millions of dollars developing.
- Integrated Gear Reduction: With 11% reduction inside the portal, you get more usable torque at the wheel, less stress on the drivetrain, and the ideal balance of road-friendly drivability and off-road performance.
- 4-Gear Portal Design: Spreads load more evenly through the box for improved durability.
- Premium Materials: CNC-machined 7075 aluminum housings paired with hardened steel gears for long-term strength under real use.
- Race-Grade Mounting Points: Steel thread inserts at every mounting location add serious durability and help hold proper torque over time—a premium feature most competitors reserve for race-only portal setups.
- Increased Oil Capacity: With 66% more oil capacity than competing portals, our system runs with greater thermal stability and longer service intervals, meaning less frequent oil changes and more time on the road or trail.
- Full System Compatibility: Retains factory ABS, parking brake, and integrates with OEM systems without compromising functionality.
- Ready to Install: Delivered as a complete system with axle shafts, extensions, and even specialty tools. All of the necessary components for a straightforward install.
- User Friendly: Built for bigger tires and daily drivability
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.
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 Rations Stay in Place - Keeps OEM gear ratios and factory engineering in place.

Fitment & Compatibility
What vehicles do the Bronco Portals fit?
They are designed for 2021–2026 Ford Bronco models.
Do these fit Bronco Raptor models?
No. These are designed for non-Raptor Bronco applications.
Are they compatible with both 2-door and 4-door Broncos?
Yes. They fit both 2-door and 4-door non-Raptor Bronco models.
Will they work with factory vehicle systems?
Yes. The system is designed to integrate with OEM vehicle systems.
Do the portals retain factory ABS?
Yes. Factory ABS functionality is retained.
Do they retain the factory parking brake?
Yes. Factory parking brake functionality is retained.
Can they support larger tires?
Yes. The portal design helps support larger tire fitment.
Performance & Capability
What is the main performance benefit of portal boxes?
Portal boxes provide true ground clearance at the wheel hub, increasing clearance in a way that suspension lifts alone cannot.
Do these portals add lift?
Yes. They add lift through the portal design, rather than relying only on suspension height.
Do they include any gear reduction?
Yes. They feature an 11% gear reduction.
How does the gear reduction help performance?
The reduction helps deliver more usable torque at the wheels while also helping reduce drivetrain stress.
How do they improve off-road capability?
They increase ground clearance, support larger tires, and improve torque delivery, all of which help enhance trail and obstacle performance.
Are they only meant for hardcore off-road use?
No. They are designed to improve off-road capability while still maintaining practical on-road drivability.
Driving Feel & Factory Features
How do portal boxes compare to a traditional suspension lift?
Because the lift is created at the hub, they help preserve more of the vehicle’s factory suspension geometry than a conventional suspension lift.
Do they affect daily drivability?
They are designed to balance increased off-road performance with usable daily driving manners.
Will the vehicle still feel integrated with factory systems?
Yes. The portals are designed to maintain compatibility with OEM vehicle features and system functionality.
Do I lose any core factory features?
No. Key factory functions such as ABS and the parking brake are retained.
Engineering & Materials
What kind of portal design is used?
The system uses a 4-gear portal design.
Why use a 4-gear design?
The 4-gear layout helps improve load distribution and overall durability.
What materials are used in the housings?
The housings are made from CNC-machined 7075 aluminum.
What materials are used for the gears?
