The time comes when the next necessary step is to install larger tires,
however the largest tire that will fit on a stock TJ is 31" x
10.5". I already had BF Goodrich Mud Tires & I wanted to move to
a larger size. I spent a long time deciding which lift kit would be the
most appropriate for my Jeep. I wanted a larger tire but not extremely
large. I decided on the Mickey Thompson Baja Claw (see
below). The
Baja I felt would suit me best was the 33" x 13.5", it would be noticeably
larger than my 31" x 10.5" BFG M/T's but would not require
me to invest in a stepladder to get in & out!!
This is when the research began!! I spent a long time posting questions
on Dirtroad.com's Jeep Forum pages, questioning many fellow Jeepers through
there web pages & reading as much material as possible. The
choice of manufacturer seemed obvious after a short amount of time... Rubicon
Express seems to manufacture the lift kits of choice, for many Jeepers.
I spent a lot of money purchasing my Jeep. With that in mind, I saw no
choice other than getting the best kit possible, one that would not only allow
me to put larger tires on, not only improve my off-road capabilities but also
retain a ride similar to stock, if not better! I realized that that was a
tall order but from the the experience of people I talked to, the
"Ultimate" Lift Kit provided that quality. The secret is the CV
Drive-shaft, Slip Yoke Eliminator and adjustable upper control arms. The
CV Drive-shaft & SYE reduce the angle from the transfer-case to the rear
pinion. The adjustable upper control arms allow the angle of the pinion to
be adjusted as required. By reducing this angle, driveline vibration is
virtually eliminated & in my case never there!! The adjustable track
bar that comes with the kit also helps correct the steering geometry that is
changed by lifting the Jeep's suspension.
The Rubicon Express "Ultimate" Lift Kit - came with the
following:
 | 4 x Coils |
|
 | 8 Control Arms (uppers are adjustable) |
|
 | 2 x Rear Extended Swaybar Links |
|
 | Front Adjustable Trackbar (w/helm joint) |
|
 | 4 x Long Travel Shocks ( I opted for OME) |
|
 | Front & Rear Bumpstop extensions |
|
 | Stainless Steal Flexible Brake Lines (front) |
|
 | Swaybar Disconnects |
|
 | Rear Trackbar re-location Bracket |
|
 | Rear CV Drive shaft (custom length) |
|
 | RE Slip Yoke Eliminator Kit |
|
|
Installation: I won't even begin to detail step by step
instructions on how to install the lift, as there are many detailed instructions
available on other Jeep owners personal Jeep pages. I will explain a few
problems I encountered during the installation & recommend two web sites
that provide detailed instructions that I used. Harry Brosofsky's Harryworld
Jeep TJ Site (unfortunately no longer available) is a valuable resource for lift instructions & other info,
and Chad
Crowell's instructions for Rubicon Express lifts. A couple
installation pointers though, that I ran into that I did not read anywhere
before taking on the project!!
| 1. DO not remove rear passengers side trackbar mounting bolt, it is
very difficult to get back in. It is not required to be removed
we learned that the hard way!!! |
|
| 2. If you upgrade to Old Man
Emu shocks make sure you buy Tera-Flex
rear shock re-location brackets.
You may want to notch or cut out a 1" x 3" piece of the edge of
the lower spring pad, the large shock canister will not mount without
these modifications. I bought the re-location bracket from Mepco
4x4. |

Installation Time: I was lucky enough to
have the assistance of a master mechanic Ted Gawlick who happens to be my
next-door neighbor. With Ted's assistance (especially with the slip-yoke
eliminator installation), it took us 16 hours total over a three weeknight
period! No doubt we would have been done faster if we did it on a
weekend. All in all the installation went well and aside from having to
have the alignment done after the lift, the lift was installed perfect no
driveline vibration from day one!!
Cost: Unbelievably
expensive!!!! Not only was the lift $1600+ USD, the upgrade to OME Shocks
was $80 USD, the optional RE Tie-Rod was $134 USD, shipping was a ridiculous $200 USD, I got nailed with an additional $155 CDN in
duties & had to pay $105 CDN for the Tera-Flex re-location brackets
(including shipping). The grand total pounds in at $3600+ Canadian
Dollars. Aside from the whopping cost, I believe the lift is the best lift
available, and could not be better made (it's just a shame I'm now broke!!)
 | Actually 33-1/2" x 12.5" |
 | Bias Ply with 6 ply sidewalls with aggressive side-biters |

These tires are my second set of Claws, one size larger than my
previous 33" meats. Claws have gained a spot in the top five
off-road tires (With Interco's TSL & Boggers, Goodyear's MTR's, BF Goodrich
MT T/A's). They work well in most off-road conditions and are
acceptable on highway conditions. In the mud, they have good self
cleaning abilities, the soft rubber makes them grip well on rocks
(especially down to 8PSI) and they all round are a very capable off-road
tire. For some reason all Mickey Thompson tires seem to be
undersized compared to there rated size, however in my situation it's OK
since I don't think I'd have enough space for a true 35" tire. I
know from my previous set they can take a beating. I like the look
and I am able to get a good price, so when time came to jump to the next
size I thought I'd stick with the Claws! Mounting tire this big on
aluminum wheel with a bias tire can be tricky to balance (especially
static balanced), the tire guy I used took his time and actually
re-mounted two of them to reduce the amounts of weights required, the end
result was a quality mount. Update May 2001 - I can now say,
after having used Claws for many
months now, driving with my second set & driving a couple long distance drives (not to mention
Toronto to Virginia & back) that I am very please with these
tires. The treads are wearing well for a bias mud tire, although I do rotate them with
every oil change. They work great on the type of trails I do, &
when aired down to 8 - 10 PSI they grip amazing. A word of
caution.... when driving long distances on highways at high speeds,
the Claws get hot (you can even smell the burning rubber), they are prone
to losing some CHUNKS of rubber when there in this soft pliable state,
don't over-do-it! They are rather loud too at high speed, me &
my girlfriend have a "no talking" policy while driving over 110
KM/ hour :) Cost: $1300 CAN (plus $150 for
balancing/mounting - less $750 for sale of 33"s)= $700.00 CAN |

15" x 8" Hot Forged aluminum one piece
wheel, strongest aluminum available. Not brittle like cast
aluminum, rather strong like steel wheels. |

High polish finish. |
One of my biggest debates throughout the whole process of
getting my Jeep lifted was.. What size wheels do I use on a 12.5"
wide tire that is able to be mounted on a wheel 8-10" wide?
Again I made my decision based on the experience of fellow Jeepers who had
already made that decision & were able to steer me in the right
direction.
The advantages of the 8" wide rim were: Less
chance of damaging my wheel while off-roading, as it is better protected,
less chance of loosing my bead while off-roading with lowered tire
pressure & it's Cheaper!! That was good enough for me. I
am extremely happy with my choice the combination of tire & wheel look
amazing!
Cost: $ 110.00 ea (USD) plus $124.00 shipping
(USD). Again the amazing price was compliments of my Grandfather's
relations with Mickey Thompson.
Installation: I had a local company Tire
World mount & balance the tires. I had to pay $15.00 ea
(CAN). Although they were able to balance the tire's on the rims,
the amount of weights they used seems ridiculous. I will have to
watch to make sure I don't loose any weights.

The stock steering dampener worked, however with the 33" Claws I
noticed that when I was traveling fast on roads & I hit bumps, the
tires would take over, wanting to follow the groove or my steering wheel
would jolt into the bump. Don't get me wrong it wasn't a safety
issue or anything like that, it was just not like stock. For the
small price of a new steering dampener I figured I couldn't go wrong... at
worst it would remain the same, at best it would be better. Since my
shocks were Old Man Emu (yellow), I wanted a matching dampener!! OME
to my dismay does not make steering dampeners for TJ's. Oh well, I
decided to go with the trusted ever popular stock replacement.... Rancho
steering dampeners. To solve my little aesthetic problem I ust
bought a can of yellow pant & gave it three coats before I installed it!! It's now a fake OME
dampener (I like to think of it as a
prototype OME!)
Installation: Straight forward, although those jam bolts
are always difficult to get out. A little tip I got, do yourself a
favour and don't hammer the end of the bolt after you remove the nut (the
intuitive thing to do), rather hammer the side of the housing it is
mounted too, the nut will just fall out!!! I promise (same goes for
the bolts in the tie rod!! next upgrade). I decided not to install
the rubber boot that comes with the dampener, it would probably just fill
up with mud, and since the shock is self cleaning I figured why bother!!
Cost: $96.00 CAN, well worth it, I noticed a difference
right away & the new dampener solved my problem!! |

Lets face it, the first thing that's going to hit an unseen rock in
your path is your tie-rod. Do to the tight front end space in a TJ,
the tie-rod is mounted in front of the Dana 30 axle housing, in a very
vulnerable spot. Although I have never damaged my stock tie-rod, it
looks pretty flimsy & it is. When I bough my lift I figured
what's an extra $134.00, at that point it's irrelevant!! SO I said
throw one in. As my luck would prevail I did not receive my new RE
tie-rod until 2 months after I had already installed my lift :-( Apparently
the rods were available, but RE was out of tie-rod end &
was having problems getting supply. I really wanted to install it
before I went to Camp Jeep 2000, but no luck. The day I got home
guess what UPS tried to deliver while I was away.... Needless to say
I did get it & it is much more impressive than the stock unit, it's
pretty, heavy duty & it looks to be well made.
Installation: 20 minutes, like the steering stabilizer,
the trick to the bolts is hammering the side of the bolt housings rather
than the actual bolt. They came out relatively easy. I
measured the stock unit adjusted the ends of the new rod to match the
length & installed the new tie-rod, no problems.
Cost: $134.00 USD, expensive but well made & at least
I don't have to worry so much about sneak up rocks in my way!! |
Update - Lift & Rims are now installed as of June
30th/00.
