We were impressed with the 2011 JK’s interior updates. Once we tested the 2012 and experienced the powertrain upgrades, it was time to procure a ’12 and build it for street and trail use.
Synergy Suspension offers control arms that are adjustable on the vehicle, making adjustments as easy as loosening a pinch bolt and turning the adjuster. Because of this, we decided to use Synergy’s Stage 3 short arm suspension that includes everything needed to turn a JK into a competent trail vehicle.
Bent OE JK frontends and failed ball joints are common. Dynatrac’s ProRock 44 Unlimited housing is extremely strong. The 44 Unlimited has added steering caster engineered in to retain proper steering angles on JKs lifted 2.5 inches to 6 inches. The shock mounts are moved to provide better shock-to-frame clearance under full articulation. Dynatrac ball joints are infinitely better than OE and are rebuildable. This was for us. Randy’s Ring and Pinion sent their excellent Yukon 4.88 gears for the Wrangler.
We’ve used Expedition One bumpers before. Their Basic DX front bumper is lightweight and doesn’t look bulbous. Their tire carrier rear bumper opens with one easy motion using the tailgate latch. The tire doesn’t rattle, either.
Our friends at Dixie 4 Wheel Drive in St. George, Utah, made quick work of ’12, changing it from a mild-mannered Rubicon into a trail tamer that works well on the highway, too. If you remember our Sleeper JK two-door project from last year, you’ll find some of this familiar. Sleeper worked so well we duplicated some of it. Check out the photos for more.
