Rubicon Express Spring-Over Kit

Preparation

Parts

For the relatively small number of parts which came with the Rubicon Express (RE) lift kit, it took a remarkably long time to install. The parts included:

  • 4 Doetschtech shocks
  • 2 Front shock tower mount converters
  • 2 Front brake line extensions
  • 1 Rear brake line extension
  • 4 Anti-axle-wrap spring perches
    The anti-wrap spring perches are basically perches which have 8"x2"x1/2" thick plates welded on top. These plates press against the spring to limit axle twist.
  • 1 Track bar axle mount extension
  • 2 Transfer case lowering bars w/6 nuts & bolts

I also recommend that you buy a complete set of spring u-bolts so you don't have to re-use your old ones and set aside cash for getting the rear driveshaft lengthened after the lift. Some rustproof paint would be good, too.

Tools

To do this job without losing your sanity, I am going to list all the tools we used in order to do the installation. Some are required, some aren't but are highly recommended.

  • Pitman arm puller
  • Complete set of wrenches and sockets
  • 4 Jackstands
  • Floor jack and a standard scissor or bottle jack
  • BFH (aka: a large hammer)
  • Torx bits (for the brake line mounts)
  • Large adjustable-grip pliers (for the parking brake line)
  • Drill (preferably a half-inch)
  • Drill bits
  • Sander or wire wheel on an angle grinder
  • Welder (or the services of a welder)
  • Measuring tape
  • Angle finder
  • Needle nose pliers

Before You Begin

Unless you're working on a new vehicle, I suggest that you spend the weekend before the installation inspecting your vehicle's brakes, steering linkage, and other parts to see if they need to be replaced. In my case, I discovered that my rotors were badly gouged and the brake pads were destroyed. Another set back occurred when I was about to install the new pads and discovered that they gave me a mismatched set. That is not the kind of event that is helpful when you've spent days working on your vehicle and you're getting blisters from the knurled handles on your ratchet wrenches. Avoid my mistakes: take care of the little stuff the prior week if you're hoping to have the RE kit installed in a single weekend.

Friends

Unless you enjoy doing things the hard way, you will NEED friends to help you install this kit. Commit yourself to the fact that they will one day call upon you for a similar favour and if you don't comply, you'll wake up with a horse head in your bed one morning. But I digress...

Work Area

I was expecting this installation to take at least 10 hours so I cleaned out the shop (a big job in itself) to make room for my Jeep. My anesthesiologist for this most difficult of surgeries was my good friend, Rob Bryce, who came over for the weekend to help me with the installation.
