Description
Transform your 3rd-gen Tundra into a clearance monster—without ruining daily manners. The 74Weld NGA Portal Axle Kit raises your axles (not just the chassis), delivering true underbody clearance, a 1.22:1 hub reduction (22%), and an approx. 3.88" lift from the axle centerline. The result: confidently run 35–37" tires with far less stress on the driveline, while preserving factory-like steering feel, CV angles, and ride quality.
Conventional lifts push suspension geometry out of spec. Portals lift the axles themselves, protecting diffs, control arms, and steering from trail strikes—exactly why Ultra4 and desert racers trust 74Weld engineering.
Why portals on a 2022+ Tundra
-
Real ground clearance: Axle-centerline gain moves the vulnerable bits higher over rocks, ruts, and ledges.
-
22% torque multiplication at the hub: Offsets big tire diameter, often avoiding a diff re-gear and reducing strain on the transmission and axles.
-
Keep OEM road manners: Flatter arm and tie-rod angles at ride height maintain composed on-road behavior—great for long trips and towing.
-
Race-grade hardware: Billet 7075 knuckles (steel inserts) and billet 6061 portal boxes—precision-machined for full-size truck abuse.
-
Brake system ready: Dedicated front and rear rotors with factory ABS compatibility for consistent, predictable braking.
-
Built-in stability: +2.75" per side (≈ +5.5" overall) track width improves stability and scrub characteristics while retaining stock suspension components.

Wheel & tire guidance
-
35–37" tires are commonly achievable with portals; final fitment depends on wheel specs, bumpers, alignment, and trimming.
-
Confirm caliper/rotor clearance and choose offset/backspacing that accounts for the +2.75" per side increase. We can spec a proven wheel package for your Tundra build.

FAQs
Do I still need to re-gear?
Often no. The 22% hub reduction offsets the effective ratio change from larger tires, letting many owners run 35–37" without opening the diffs. Payload, towing, terrain, and tire size ultimately decide.
How is a portal lift different from a suspension lift?
Suspension lifts raise the body but keep axles at the same height, which can worsen CV and steering angles. Portals raise the axles, delivering real clearance under diffs/arms while preserving geometry.
Will ABS and traction systems still work?
Yes—the kit is factory ABS compatible. Verify system operation after installation; initialization/recalibration may be recommended.
