Our new 2012 JK is here. The 2012 features a new powerplant, the 3.8L Pentastar V6 that produces 285hp and 240 ft/lbs of torque. Ours is equipped with a 5-speed automatic, and driveability is far better than the 2011 and earlier JK’s. Jeep is claiming increased fuel economy. Dana 44′s with electric lockers are standard equipment for the Rubicon JK’s.
Upgrades so far include a 3″ Teraflex suspension with a full set of adjustable control arms, Hanson Offroad bumpers front and rear, 35″ BFGoodrich KM2′s and a Warn 9.5 cti winch. We wanted to run the stock Rubicon wheels so we also installed a set of Spidertrax 1.5″ wheel spacers to hopefully eliminate any rubbing issues.
The new ProCal Module compatible with the 2012 model just arrived, so we changed the differential gear ratio to 4.88 without putting the Jeep into limp mode. The ProCal also allowed for recalibration of shift points, speedometer and numerous other features. A set of Hanson Offroad rocker guards is on the way….stay tuned. Hopefully the weather will hold out long enough for a late season Rubicon Trail Run.
