We’ve seen test mules of the next-generation 2018 Jeep Wrangler before, but this is the first time we’ve gotten a chance to see what the JL Wrangler will be packing underneath. After years of speculation and rumors, the 2018 chassis has been spotted, and it features everything a Jeep fan desires: body-on-frame construction, solid axles, linked suspension, and a diesel powertrain option.

This latest round of spy shots is the first time we’ve seen the JL chassis, and now we can confirm there will be no independent front suspension, with this Rubicon version packing Dana 44 axles front and rear. The suspension retains the same link-style setup with coil springs and monotube shocks and skidplates to protect everything from trail damage. The tires mounted to this mule are the Goodyear Wrangler Duratracs, which come on the Ram Power Wagon and will likely replace the BFGoodrich tires currently offered on the JK.

The biggest surprise we saw when looing at the photos was the diesel exhaust fluid (DEF) tank mounted inside the frame with its own skidplate. We can’t see a diesel particulate filter (DPF) in the photos, so this is likely an unfinished design or a gasoline version testing DEF tank location. Either way, we are one step closer to actually having a diesel Wrangler.

With spy shots of the next-generation Wrangler chassis, body, and even the expected pickup, the 2018 Wrangler is so close, and we can’t wait to see it come together in one sweet package and then take it to the trail. We’ll update you with more information as it becomes available at fourwheeler.com
