Jeep CJ-7 on 43" SX Swampers and 1 ton axles

CJ lovers, this build is for you...

This is how the Jeep first rolled into the shop

The owner of this Jeep wanted a proven setup. Dan DuBose is the owner of Motobilt and the creative designer of this amazing CJ-7.  He has built world class off road race cars with the most advanced technology of the time.  With the customer's budget concerns, we opted to utilize leaf springs by combining budget friendly parts that are trail capable.

The tear down process began by stripping the axles and suspension from the frame.

Base model with no tube work shown.

The use of of a Motobilt full width axle kit  and rear stretch kit are the 2 key components in this build.  They allowed the use of full width one ton chevy axles front and rear.  The rear stretch kit also allows for a wheelbase improvement of approximately six inches.  This increase in wheel base allows for better drive line angles, departure angles and increased hill climbing abilities.

Allows for a shackle reversal

This is the Stinger version. 

Below, the stretch kit can be seen in this picture along with the rear axle moved back 6 inches.

 Here you can see how the shackles mount to the back of the bumper

Includes 3/4" D ring mounts

The benefits of the full width one ton axles are not just their amazing strength, but the stability they provide.  The one tons are approximately 14 inches wider overall than the stock CJ axles that came factory equipped.  This extra clearance allows for the use of massive off road tires.  Initially, a set of 39.5 x 18 boggers were going to be utilized.  That was until a set of 43" SX super swampers and 17" HD Trail Ready beadlocks became available.

This grill hoop is not available for purchase

A custom roll cage was built that utilizes a set of Custom PRP seats front and rear.

The owner of this beast installed a Fuel Injected Chevy 383 stroker motor with a TH350 automatic and an Atlas 2 speed transfer case.

Leaf springs can flex!

With the shock hoop kit installed we were able to mount longer shocks so this CJ could flex out

Those 17" Trail Ready's will get the job done!

The Jeep is getting closer to being finished. Be sure to check back in as we update the progress on the build. Testing the suspension out.

All Painted up and looking good.

We were able to use the YJ behind the seat fuel cell since we custom mounted the rear seat.

This Full width kit has a custom in house built grill hoop. It has to be welded and fitted to the frame which is why we do not offer it as an option to be shipped.

The 17" Trail Ready beadlocks will keep the 43" Super Swampers firmly in place.

This custom one of a kind dash and roll cage were built in house.
