We’ve found that using a
deep sump oil pan will cause
interference with the crossmember
mount; however, a stock oil pan
works well.

This is the correct boot
position for the twin sticks.
When installing, be sure they do
not hit the floor when in full
movement.
As featured in 4 Wheel Parts Off-Road Adventures, October / November 2000
nies offer disc brake conversions for stock axles so check
around before you order your Atlas II.
We marked the firewall location and removed the body
for easier access. Removing the body is not necessary,
but we wanted to restore the body at the same time.
Our bodywork was performed in-house by Scott
Corgiat with phenomenal results, and sent out to be
painted and have a liner sprayed in. With the body off, we
installed Warn’s Black Diamond XCL suspension system.
The flexibility of this kit is incredible due to the fully
adjustable Fox coil-over shocks. Our Currie axles arrived
and we went to work mating the suspension to the driv-
etrain. We measured the driveshafts and had them cus-
tom fabricated by Tom Wood’s Custom Driveshafts. Tires
now became a concern. Which one? How big? Radial?
After much researching and many games of scissor-pa-
per-rocks, 35x12.50 15 Super Swamper TSL radials were
chosen to put the power to the ground.
We reinstalled the body and front clip. The floor was
modified so that the twin Atlas II sticks did not bind or hit
the body. This is a critical step because most shifting
problems we’ve seen have been traced to improper instal-
lation. We installed our aluminum Be-Cool radiator and
wired the motor up using a Howell wiring harness. The
thick bracketry on the motor forced us to use an electric
fan on the front of the radiator. This seems to work fine.
The crawl ratio of the YJ is 60-to-1. Not a bad num-
ber considering that stock is somewhere around 38-to-1.
The horsepower that the motor develops now can be uti-
lized more effectively by using less tire speed to conquer
obstacles. This slower and controlled speed equals safer
four wheeling because you have more time to react in a
dangerous situation. The YJ now feels lighter and is more
responsive thanks to the new powerplate.
