#MTSEMA18: 3 Fixes For Jeep JL Front Axle

SEMA 2018

Stuart A. BourdonPhotographer, Writer

Having put considerable off-road miles on it, we think the new Jeep JL Wrangler is one heck of an off-roader right out of the box, no doubt about it. As you may have already seen, the aftermarket has been in high gear producing parts, pieces, and accessories of all kinds for enthusiasts to build their dream Jeep JL. However, for some longtime Jeepers, the bad taste left by the front-axle-disconnect system on the Jeep YJ still lingers.

We get that there were valid reasons behind the decision to use a more advanced and better engineered front-axle-disconnect system on the new Jeep Wrangler JL, and it’s claimed to be a much more reliable system, but for some Jeep enthusiasts it will just have to be fixed. The easiest and best way to do that is to replace the entire front axle. We found three manufacturers that already have exactly what you need to do the job. Dana-Spicer, Dynatrac, and G2 showed off complete “44” front axle replacements ready to ship. Check out the photos below to see what’s available to “fix” and upgrade the stock front axle on your Jeep Wrangler JL.

Dana offers the Ultimate Dana 44 AdvanTek for the Jeep Wrangler JL. The Ultimate Dana 44 AdvanTek axle is a bolt-in replacement upgrade available in 4.56, 4.88, 5.13, and 5.38 ratios; SAE 4340 chromoly axleshafts; thicker 1/4-inch steel mounting brackets; high-clearance carrier design; 1/2-inch increased ground clearance; nodular iron differential cover; extra ribbing for strength; thicker 9.5mm axletube; and upgraded 1410 U-joints. Dana also has an Ultimate Dana 60 front and rear axle replacement upgrade for the Jeep JL. Go to spicerparts.com for more details.

The Dynatrac ProRock 44 for the 2018 and newer Jeep Wrangler JL is a direct bolt-in that features significantly stronger axletubes and end forgings, and eliminates the front-axle-disconnect (FAD) system. It includes one-piece U.S.-made and heat-treated chromoly axleshafts. Dynatrac boasts that the ProRock 44 for the Jeep JL will provide JL owners the ability to run tires up to 38 inches tall without fear. By the way, Dynatrac also has ProRock XD60s for JL front and rears, and ProRock 80s for JL rears. For more information, check out dynatrac.com.

G2 Axle & Gear’s Core 44 direct bolt-in upgrade for the Jeep JL is said to handle up to 40-inch tires. The upgrade features the company’s unique centersection that helps prevent gear deflection, larger 3-inch-OD and 5/16-inch-wall axletubes, forged chromoly ends with twice the material of the factory C-ends, 1/4-inch-thick steel brackets, heavy-duty all-metal ball joints, and chromoly axleshafts with 1480 series U-joints (equivalent to a 1-ton). The company also makes an air-operated selectable locker with a manual override for the new JL Core 44. For all the details, go to 4wheelparts.com.
