Nena Knows JL
Great Magazine! The Nena Knows Jeeps column about the JL (Aug. ’18) was very informative. It has left me with a couple questions though.
1: Is the Mopar 2-inch lift a leveling kit, or a complete lift kit?
2: Do you plan on adding lower axle gearing to the Jeeps you add the 35- and 37-inch tires to?
Keep up the good work!

Thanks for the kind words! The answers to your questions are:
1. The Mopar (mopar.com) 2-inch lift is a complete kit, including springs, sway bar links, Fox (ridefox.com) shocks, and front lower control arms. Note that we have incorporated a corrected spring retainer into this lift kit, as we experienced spring bowing that caused coil contact with the bumpstop. This corrected front spring retainer for JL is available from Mopar, as well as Daystar (daystarweb.com).
2. We do not regear the JL with 35-inch tires, but we do use the Mopar Vehicle Protection (MVP) Custom Calibration contract to accurately reprogram for tire size. That program also allows you to reprogram for regearing. We will likely use the AEV (aev-conversions.com) ProCal for all of this when they become available for JL. The Mopar Custom Calibration is provided only by a service tech, and only over a period of two months. On our JL Rubicon models with 37-inch tires (we only have Rubicon
JLs at this time), I have found the difference noticeable enough to desire regearing. I personally would prefer to regear to a 4.56:1 axle ratio, since the transmission seems to hunt a little more on hills with the factory 4.10 gears. Also, with the extra weight of 37-inch tires and the larger circumference, it does diminish some of that great JL pep on the highway, and the Jeep doesn’t crawl quite as well as I would like in the big rocks. Happy trails.
