February article date just came across my Instagram feed today. Please excuse if this is a duplicate.
Nice hardware and out of my check book range but as the article proves, these may make good sense for some.

These portal boxes are where the magic hides, and they are available for factory axles (although upgraded axle housings are recommended for tires over 35 inches, with or without portals) found under Jeep Wrangler JK (2007-2018), Wrangler JL (2018-present) and Gladiator JT (2020-present) models. The boxes are shrunken-down versions of 74Weld's Trophy Truck and Ultra4 portal boxes, specially designed to attach to the front and rear axles of these Jeeps. The boxes feature four gears and add a 1.19:1 ratio to the axles while adding 3.5 inches of lift and 3.5 inches of track width per side. This is like the result you get from spending thousands of dollars on a 3.5 inch suspension lift, then spending thousands of dollars to re-gear your axles.
And there's more—the gear reduction of the portal boxes at the axle ends decreases the amount of stress applied to the axle shafts, the ring-and-pinion, driveshafts, and basically everything upstream of the boxes. The portal boxes are also compatible with the JK, JL, and JT speed sensors for ABS compatibility on all four corners. And the lift achieved with the portals allows clearance for 37-inch tires. The portal boxes also add one-ton unit bearings, locking hubs up front, and drive gears in the rear. Scrub radius is optimized with 17-inch-minimum wheels with 8-on-6.5-inch lug pattern and a recommended 5-to-6-inches of backspacing. The system maintains stock front-inner 1350 shafts and U-joints and upgrades the rear axle shafts to double-spline axle shafts, included with the kit. JL Rubicon and JT keep their stock brakes while JL Sport/Sahara and JK upgrade to JT brake calipers (supplied) with new eight-lug rotors. The Jeep portals, as of KOH 2022, are $20,000 a set, subject to change. That's not cheap, but remember you are saving money on a suspension lift, axle gears, and installation of all that stuff".
