Jeep Wrangler JL Upgrades
THE PAINT IS BARELY DRY ON the new JL’s rolling off FCA’s assembly line, as the aftermarket busily churns out performance upgrades. But it’s worth noting that you don’t need a JL to enjoy these upgrades. They are available for earlier Wranglers as well. Here are a couple that caught our attention recently;
DynoMax® Performance Exhaust
adds a new Jeep Wrangler JL performance exhaust system for the 4-door model. The centre of the system is a DynoMax Super Turbo™ muffler for a mild, true performance sound. Inside the muffler are spun-locked heads and flow-director technology, helping to maximize exhaust flow. Constructed from stainless steel, the muffler includes a polished, 304-grade stainless steel cover that helps to provide an attractive mirror finish. The new kit includes 2.5-in. stainless steel, mandrelbent piping to help extend protection against corrosion and was engineered to maintain factory emissions routing for form, fit and ease of installation. The system is finished with a pair of 4-in. stainless steel buffed and polished exhaust tips, embossed with the DynoMax logo. All necessary hardware, hangers, clamps and other accessories plus highly detailed, step-bystep installation instructions are included.
If you don’t own a JL, fear not as they have exhausts for Jeeps 1986 and newer.
Dana has introduced a new line of aftermarket
Dana axles and Spicer® drivetrain components
for the Jeep® Wrangler JL. But doesn’t the JL already come with improved and strengthened Dana and Spicer components you ask? Yes, is the answer.
The new JL comes with redesigned Dana axles as standard equipment. The Sport and Sahara come with Dana 30™ axles in front and Dana 35™ AdvanTEK® axles in the rear, while the Rubicon comes equipped with Dana 44™ AdvanTEK® axles in front and rear. Each of these axle designs have been improved and strengthened for the Wrangler JL.
“The new Jeep® Wrangler JL features extensively redesigned Dana axles as a part of its standard equipment package,” said Peter Cirulis, vice president of customer experience, strategy, and product planning for the Dana Aftermarket Group. “However, there are always enthusiasts who want to push the envelope, and these Dana and Spicer upgrades build on our proven, market-tested technology to meet the rigorous demands of off-roading. Whether you are going to a remote fishing spot, or rock-climbing in Moab, Dana has created the upgrades you need to enjoy the journey as much as the destination.”
For the serious off-roader, the Dana aftermarket upgrades include heavy-duty chromoly axle shaft replacements for the stock units, and a range of AdvanTEK® performance ring and pinion gears so owners can select their optimum ratio. For maximum performance, owners can upgrade the standard Dana axles with the Ultimate Dana 60™ front and rear axles.
These bolt-in replacement axle
are available in 3.73, 4.10, 4.88, and 5.38 ratios and come with an Eaton® E-Locker. The axles feature:
•35-spline, nickel chromoly steel axle shafts designed for higher torque, larger tires, and offroad punishment;
•a greatly enhanced carrier with Spicer® performance ring and pinion gearing;
•massive SPL® 70 u-joints, exclusive to Dana;
•full-float design for greater load-carrying capacity; and
•upgraded, heavy-duty brakes with plug-and-play antilock braking system.
Spicer Chromoly Axle Shaft upgrades for the Jeep® JL are available in a number of configurations for the Dana 30™(front), Dana 35™ AdvanTEK® (rear), and Dana 44™ AdvanTEK® axles (front and rear). Spicer aftermarket axles are available to replace the front axle disconnect (FAD) feature on the stock Dana 30™ and the Dana 44™ AdvanTEK® axles.
Spicer master overhaul and standard differential rebuild bearing kits are available for the Dana 30™, Dana 35™ AdvanTEK®, and the Dana 44™ AdvanTEK® axles.
Enthusiasts can choose from a range of AdvanTEK® aftermarket expanded gear ratios for all three original equipment (OE) axles. Four ratios are available for the Dana 30™, five for the Dana 35™ AdvanTEK®, and the Dana 44™ AdvanTEK® has six gear options for the front and seven for the rear.
“Dana has been the OE supplier of axles to Jeep® for over 75 years,” said Cirulis. “With that heritage, no one knows the Jeep® drivetrain better than Dana. We want to be first when it comes to ‘what’s next’ for Wrangler JL aftermarket parts.”
