New AEV kit bestows 2024 Wrangler Rubicon with 37-inch tires

Jeep has partnered with American Expedition Vehicles (AEV) to create three new kits for the 2024 Wrangler, the most extreme of which will offer 37-inch tires.

The three packages, in ascending order of insanity, are named as follows: Upcountry, Upcountry+, and Level II. Every upfit kit will replace the 33-inch rubber on the stock Wrangler Rubicon with either 35- or 37-inch tires. The first two kits are also available on the Wrangler Willys for the first time, replacing that trim’s 33-inch rubber with 35-inch tires.

The first rung on the ladder, Upcountry, will bring an AEV 2-inch suspension lift as well as new wheels, 35-inch BFGoodrich All-Terrain T/A K02 tires, Jeep Performance Parts fender flares, and more. The kit will cost $7476. Upcountry+ will offer a new front bumper, front skid plate, a relocation kit for the integrated front off-road camera, and more, in addition to the lift, 35s, and flares from the Upcountry kit. You’ll pay $11,599 for that option.

The big news, however, is the AEV Level II kit. Offered exclusively for the 2024 Wrangler Rubicon, you’ll get the aforementioned front bumper and skid plates, an AEV rear bumper and new tire carrier, a 2.5-inch DualSport suspension lift with Bilstein 5100 shocks, kit-specific satin-black wheels, and those coveted 37-inch tires.

The kit can be applied to both the normal Wrangler Rubicon ($20,049) and the Rubicon 4xe ($22,099). The added cost for the Rubicon 4xe comes from a replacement of the stock 4.10 axle gears to the 4.56 gears found in the Rubicon 392 and Rubicons equipped with the Xtreme 35 package, which were previously the only two avenues to getting 35-inch rubber.

Those vehicular equivalents to heel inserts will boost off-road metrics, to nobody’s surprise. Fitted with the Level II kit, Wrangler Rubicons will now boast 14.2 inches of ground clearance, 37.1 inches of water fording capability, a 50-degree approach angle, a 33-degree breakover angle, and a 43-degree departure angle. Without this kit, the best figures available were 12.9 inches of clearance, 34 inches of water fording, a 47.4-degree approach angle, a 26.7 breakover angle, and a 40.4-degree departure angle.

If the combination of AEV, Wranglers, and 37-inch tires sounds familiar, you’re not imagining things. Last year, Jeep partnered with AEV for a limited run of 300 Rubicon 392s, all created in celebration of the 20th anniversary of the Wrangler Rubicon, which came with 37-inch tires. The package proved so popular that all 300 examples sold in fewer than two hours. Proof was, as they say, in the 37-inch pudding; the customers had spoken, so Jeep set about readying a package for more than just limited-run Wranglers.

Based on a cursory glance at any Wrangler on the road, usually rolling on bigger rubber with new wheels, the package makes perfect sense. You can get yours on a first-come, first-serve basis by placing an order through a local Jeep dealer this month. Wranglers optioned with any of the three kits will ship directly from Jeep’s Toledo Assembly Complex to AEV for the upfit.
