How-to: Jeep 4WD JK Wrangler, Unlimited & Rubicon Workshop

     The JK Wrangler debuted in 2007 and replaced the TJ design. JK owners immediately went to work on this longer wheelbase model. Its improved frame structure and rugged powertrain lends itself to traditional Jeep® trail use, requiring the typical aftermarket modifications.

   Want to do your own Jeep 4WD repairs, troubleshooting and upgrades? The workshops offer Jeep technical 'how-to' projects, valuable troubleshooting tips plus a variety of upgrade product installations. See the 'how-to' articles, videos and instructional tips on the following pages!

MasterCraft's JK Wrangler Rubicon scaling Moab wall 2010

     A stock JK has excellent approach and departure angles, however, the popular, longer wheelbase 4-door option dramatically sacrifices breakover angle clearance. To meet rocky trail demands, owners lift the JK, install oversized tires, and add the usual complement of accessories! 

  Note: After exposure to the JK Wrangler on trails like Moab and the Rubicon, Moses Ludel has abandoned his time-honored mantra about the 33" tire limit! 35"-37" tires, with revised axle gearing, have become a norm for the JK Wrangler and JK Rubicon Edition, especially four-door models with the 116" wheelbase! Lots of work, lots of expense to do it right!

  This section of 4WD Mechanix Magazine will focus on tested JK modifications, trail upgrades and improvements. Send JK Wrangler questions and comments to the "4WD Tech 'Q & A.'" Moses Ludel will continue to research, evaluate and comment on developing aftermarket innovations.
