Our portal are for 4Runner owners who want serious ground clearance, improved big-tire drivability and trail-ready strength. Join the list for development updates and first access when ordering opens.
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 Jeep continues to operate like it did from the factory.
Tire Size Correction
Helps your Jeep properly account for larger tires, including corrected speedometer function, without the hassle of traditional regearing.
Portals are for the driver who wants true clearance and larger tire capability without giving up daily drivability.
