We wanted a JK that would be stealthy and work well on- and off-road. In the last issue, we detailed the installation of front and rear Expedition One bumpers and a Warn winch on our 2011 Sahara Tan JK Rubicon two-door. This month, with the help of Poly Performance’s JK Synergy long-arm suspension and other parts, we turn the JK into Sleeper, our stock-looking Wrangler that works.
While the Synergy suspension is the big news here, Sleeper wouldn’t work without the other parts we installed. The new Fox shock absorbers are stunningly good. Currie’s heavy-duty JK tie rod and drag link are outstanding, as are the Motive Gear 5.13 gears and Ten Factory hardened axles. Pure Jeep is now offering a JK evap canister relocating kit and ours fits fine. In the April 2011 issue of 4WD&SU, we detailed Dynatrac’s ProRock 44 and Pro Steer ball joints that address the weak OE frontend of the JK Wrangler. Spidertrax 1.5-inch wheel spacers allow us to run the OE Jeep Rubicon alloy wheels, helping Sleeper look stock. AEV’s ProCal programmer lets us turn off the TPMS and program tire size and gear ratio just a few of the things it does.
Poly Performance supplies excellent, detailed instructions for the installation of its JK Synergy long-arm suspension system. Read the instructions carefully and follow every step. Please do not expect this feature to be detailed enough. When installing this suspension system, read the instructions.
Sleeper looks OE, but doesn’t perform that way. Look for more next month.
