When is enough lift actually enough? For us, our
'94 XJ will be high enough when
we can run a 31" tire without any tire rub. We ran 31" tires on our Cherokee with the Old Man
Emu 2" lift on stock offset rims with just a little rub in the fenderwells while off-road.
The larger problem was the tire rub at the lower control arms when turning, greatly increasing
our turning radius and making for some embarrassing parking lot noises. We set out to fix both
problems...and a "can of worms" was opened.
To cure the control arm rub, we used new wheels with less backspacing. Easy enough, but now the
new tire and wheel assemblies were pushed farther away from the ball joints (the pivot points
while turning). This causes the tires to swing in a wide arc when making sharp turns which
reduces fenderwell clearance. To picture this concept, imagine your wrist as the ball joints.
With your fingers extended, move your wrist back and forth and notice the wide arc the tips of
your fingers make. Now try it again while making a fist and observe how much smaller the arc
is. This is the difference in backspacing of the wheels. You can see how the decreased
backspacing of our new wheels eliminated the control arm rub, but made the fenderwell-rub
much worse. One problem solved, one problem worsened.
There is only one way to fix fenderwell rub, and that's to lift the Jeep higher. Due to the
XJ's unibody construction there is no way to install a body lift. With that option non-existent,
we started shopping for another suspension lift.
We have heard a lot of good things lately about
Rancho Suspension's coil-spring Jeep lift
kits. We are very pleased with our
TJ Project's 2.5" Rancho lift,
so we decided to look into a similar lift for our
1994 XJ Project. As many of you
already know, we're not big fans of add-a-leaf kits as a method of lifting a vehicle. For us,
it's replacement leaf spring packs or nothing at all. Fortunately,
Rancho gives a choice of rear lift methods
for the Cherokee to fit any budget. Select from a replacement spring pack, add-a-leaf, or lift
block setup. After taking a look at Rancho's
very soft spring rates (240 lbs.\in. front, 186 lbs.\in. rear for the replacement rear springs)
we decided to give their kit a try.
Our kit contained new front coils, lower control arms, transfer case drop kit, rear springs
packs, and rear U-bolts (some of these components are optional and do not come with the standard
kit. Be sure to ask your local shop what is included in the kit for the quoted price).
Installation of the kit is a snap. The entire job was done in about 4 hours working alone with
common hand tools. After a quick test drive, we found it necessary to install the transfer case
lowering brackets to eliminate an annoying driveshaft vibration.
We had every intention of trying out Rancho's
new RSX shocks with our lift kit, both to satisfy our curiosity and to pass along the results to
our readers. The problem is, they didn't fit. The same model RSX shock is supposed to fit a
Cherokee with 0-3 inches of lift. The front shock was at maximum extension with the 3" lifted
XJ sitting on level ground. This would not allow any downward suspension travel, or droop, at
all. Needless to say, the RSX shocks were immediately removed. After taking some measurements
of the Jeep and determining the correct shock length, we studied
Rancho's catalog for about 15 minutes to
find the appropriate RS9000 shocks.
It quickly became apparent that our RS9000 options were extremely limited due to the bar pin
used to mount the Cherokee shocks. We were unable to find a shock of the desired length with
the appropriate bar pin mount. Our solution was to trash the bar pins. We purchased some JKS
bar-pin eliminators at our local 4x4 shop, which allow the use of a standard 5/8" hole bushing
end instead of the bar-pin. We now had plenty of shock options. With measurements in hand, we
chose Rancho #9168 (YJ Wrangler) front shocks
and #9125 (Bronco II) rear shocks. These shocks allow plenty of droop and compression travel on
our Cherokee.
The end result is that our Cherokee sits level again (the OME kit left the Jeep's rear end
higher than the front) and it has enough room to clear our 31" tires. The ride is surprisingly
smooth and balanced with the shocks set on the "Number 2" setting. With the front swaybar
disconnected, articulation is very good off road with both axles. All in all, we have no
complaints about this lift kit. We don't feel it has the refinement of the OME kits, but it
does offer us the extra height we needed along with a price hundreds less than
Rancho's Australian competition.
I apologize for the lack of pictures of our Cherokee with the
Rancho kit installed. I recently had the
misfortune of breaking my leg and it has left me couch-bound and unable to drive due to a cast
up to my hip. As soon as I'm recovered, we'll be back four wheeling again. Check out our
'94 XJ Project page for updated
pictures as soon as this cast is off!
