Rubicon Express is located in the foothills of the Sierra Nevadas, very close to the Rubicon Trail. Because of this, the Rubicon Express crew is on the Rubicon Trail as often as possible, testing and enjoying vehicles equipped with their suspension systems.
One of those vehicles is their 2007 Jeep Wrangler JK Unlimited. It started life as one of the very first Rubicons off the assembly line in 2006. Rubicon Express immediately sent the Jeep to Burnsville Off-Road, where a SRT8 6.1L Hemi V-8 and 545RFE automatic transmission were installed. Burnsville also installed a pair of Dynatrac ProRock 60 front and rear ends equipped with 5.38 Sierra gears and ARB Air Lockers.
The Unlimited received Rubicon Express' very first JK long-arm suspension system. It was recently upgraded with Rubicon Express' new natural rubber Super-Ride bushings and remote reservoir shock absorbers. The Rubicon Express suspension makes way for a set of 37x12.50R17LT Goodyear Wrangler MTR with Kevlar tires riding on Walker Evans Racing 17x8 beadlock wheels.
Hanson front and rear bumpers and OE Jeep Rubicon rocker guards protect the body. A Warn 9.5ti winch is ready for extraction duty. The interior remains stock, except for a new JK Unlimited Black Box from Mac's Custom Tie Downs in the back. The Black Box is strong and holds plenty.
The Rubicon JK was a hit at SEMA and continues to impress wherever it goes. We spent some time with it in Southwestern Utah and liked its capable performance on- and off-road. We're sure it works as well on the Rubicon rocks as it did on Utah slickrock.
