| When Laz pulled up
to the shop in his “Super Trooper”, I almost
died laughing.
I don’t have a natural foods store next door,
and I don’t sell tobacco water pipes. Who really
drives a trooper?
To my surprise, the man walked in my door! He stared
rambling off some story about taking his trooper to
the highlakes, and his buddy jumping up and down on
the front bumper to get traction.
I wasn’t really interested in the escapades
of Laz and his stoner, hippy friends. I started daydreaming
about topless college girls on beer-can beach.
The day the trooper showed up, I wanted to hide it
until I was ready to do the work.
This was a top-secret project and we didn't want the
information leaking into the wrong hands so we rushed
it over to our secret storage facility... well.. actually,
I was a little embarrassed to be working on it. (no
offense Laz).
The first thing I did was build the axles. In the front,
I used an 84 Toyota straight axle.
The first thing I did was strip it and check it out.
The knuckles had just been rebuilt, and everything else
looked great.
I replaced the stock 4.10’s with 5.29 Yukon
gears, and a Yukon install kit.
From there, I found my dumpster once again with the
stock Birfield joints. I replaced the axles with a Yukon
Birfield eliminator kit.
This kit comes with 4340 chromoly dana 44 shafts and
spicer 760x u-joints.
It also comes with new spindles to accept the larger
stub shafts. At the same time, I installed 4x4 Labs
double crossover steering arms.
With these arms, I would not need to move the steering
box forward.
It puts the draglink in front of the axle, and the
teirod in the rear of the axle. We used Chevy tierod
ends and 1.25 x .219 DOM tubing for the tierod and draglink.
For the rear, I chose to use an IFS Toyota rear.
We also put Yukon 5.29 gears in it, with a Detroit locker.
The factory drum brakes were kept, and the Isuzu e-brake
lines were adapted to hook up.
Due to the fact that it came from an IFS Toyota, we
put 1.5” wheel spacers on the front to make the
width match.
On the first day, we decided to start on the rear.
We removed the Isuzu disc brake 44. (It is a weird hybrid
cross, and I decided not to screw around with it.) We
cut the perches off the Toyota rear, and sprung it over
with the factory Isuzu springs. We used 2.5” blocks
to achieve our optimal height.
We also threw away the factory 2 piece driveline,
and cut the cross-member out. We replaced the old cross-member
with a custom bent tube one. With, the rear done, we
threw two junk tires on it to turn it around. Damn it
looked cool! 
It was now time for the fun part. Out came the BFH
and the plasma cutter!
We showed no mercy!
The sledge hammer was swinging and the sparks were flying.
It took hours to cut out that stupid IFS.
It even took longer to grind the frame clean.
In the end, we decided to plate the outside of the fame
with 3/16 steel.
For the front shackles, we sleeved the frame and bushed
it to accept Confer shackles.
For the springs, we used 2.5” Rubicon Express,
6 leaf, reverse eye springs. They gave us the exact
height we were looking for to clear 35” tires.
Once the stock Isuzu pitman arm was reamed out to fit
the double pivot Chevy draglink end, we pulled it out
front to flex it out.
Boy were we surprised!
I have never seen a trooper look so tough!
We made sure everything cleared and measured for shock
dimensions and bump-stop locations.
We pulled it back in the shop, bent up the front shock
hoops,
and started messing with the driveline. I took of the
rear driveline flange, and machined it and redrilled
it to accept a Toyota CV. We had E & J Engineering
in Auburn, Ca. make the Toyota CV rear driveline.
In the front, I did the same thing with the output
flange on the transfer case. I machined the flange to
accept the Toyota pilot, and drilled it to accept the
big pattern Toyota flange.
The big pattern Toyota flange is capable of almost
45 degrees. I also re-drilled the front flange to the
same big Toyota bolt pattern. E & J Engineering
in Auburn built the front driveline as well. We used
the high angle Toyota flanges on both ends, and an 8”
Toyota slip in the Center. By putting the slip at the
top, there was no trimming required on the crossmember.
The last part of the project was to make the rock sliders.
Beau bent up some 1 3/4" x .120 wall DOM tubing.
He mounted the sliders to the frame in 3 spots, and
capped the ends.
Despite the fact that the Trooper is a gutless wonder,
it drives like a dream! With the Rancho 9000 adjustable
shocks, the ride can be tightened up for curvy roads,
or loosed up for off-road.
Who knows, you may run into this “Super”
trooper on Rubicon some day.
