Revolutionary portal axles for Jeep Wrangler from 74Weld

After 20 years in this industry, it does not happen every day that we come across something that can really change the terrain aftermarket world. This new Jeep Wranglers product from 74Weld may not change the terrain aftermarket world, but we bet it will. If you have spent time with Quad bike magazine or at, you’ve heard us talk about portal axles before. Tested in Ultra4 race cars and Trophy Trucks, portals like these from 74Weld Ultimate Jeep give you additional ground clearance, room for larger tires and shifting. These are things that generally come from a combination of other aftermarket modifications, but portals do all of this at once. Here are the details.

74Weld Ultimate Jeep Portal Boxes

These portal boxes are where the magic lies, and they are available for factory axles (although upgraded axle housings are recommended for tires over 35 inches, with or without portals) located under the Jeep Wrangler JK (2007-2018), Wrangler JL (2018- current) and Gladiator JT (2020 Present) models. The boxes are shrunken versions of the 74Welds Trophy Truck and Ultra4 gantry boxes, specially designed to be attached to the front and rear axles of these jeeps. The boxes have 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 the result of spending thousands of dollars on a 3.5-inch suspension lift and then spending thousands of dollars to shift your shoulders.

And there is more – the gear reduction of the gantry boxes at the shaft ends reduces the amount of stress applied to the shaft shafts, the ring and the gear, the drive shafts and basically everything upstream of the boxes. The portal boxes are also compatible with the speed sensors JK, JL and JT for ABS compatibility in all four corners. And the lift achieved with the portals allows space for 37-inch tires. The gantry boxes also add one-ton unit bearings, locking hubs at the front and drive gears at the rear. The scrubbing radius is optimized with 17-inch minimum wheels with an 8-by-6.5-inch heel pattern and a recommended 5 to 6-inch rear distance. The system maintains bearings front-inner 1350 axles and U-joints and upgrades the rear axle axles to double-spline axle axles, which are included in the kit. JL Rubicon and JT keep their bearing brakes while JL Sport / Sahara and JK upgrade to JT brake caliper (included) with new eight-heel rotors. The jeep portals, starting with KOH 2022, cost $ 20,000 per set, subject to change. It’s not cheap, but remember that you save money on a suspension, axle gears and installation of all that.

74Welds recommendations

As we said, these revolutionary portals can be screwed to your JK, JL or JT axles, but Currie, Dynatrac and 74Weld recommend an upgrade for all jeeps running over a 35-inch tire, whether portals are used or not. It’s mostly Jeeps’ fault for trying to save some unsprung weight by selling these vehicles with relatively thin and weak axle housings. Fortunately, both Currie and Dynatrac have upgraded housings, including the Dana 60 housings, which use JL outer knuckles (which will work with these portals) and the portal boxes are also compatible with both companies’ semi-float rear 60 axles.

Other cool parts: Crawler portals from 74Weld

Only with the risk that the portals are not available for some of the most popular 4×4 cars out there (and we are sure that there will be more OEM applications), we looked at something even cooler at the 74Weld stand at KOH 2022. These are the company’s Two-Gear Crawler portals which are more of a construction platform for those who build rather extreme rock crawlers. 74Weld sells the portal unit and internal knuckle-C as a set that can be welded to a customer’s housing. The third part of the housing shown was turned over to represent a common way for builders to compensate for the two-speed portal changing direction of rotation (not required on four-speed Jeep planets above). Some key points for the Crawler portals: a 1.83 Gear Reduction, a 4.27-inch drop from the centerline of the axle, 40-spline upper and lower gear axles and 40-spline drive bearings. The price is similar, $ 5,000 per corner at the time of publication for the crawler portals, subject to change.
