Epic Polymer's Ultra4 Grand Cherokee WJ Buggy Build

well its time for a new buggy build. I want something thats going to be fast capable and have some real lockers.

LQ9 motor
TH400
atlas
9” or 14 bolt drop out rear (depending on what I get for my current rear axle) Straight axle.
2.5” triple bypass shocks, 2.5” remote res coilovers, 2” air bumps on all 4 corners
Front and Rear sway bar….YAA! finally
New chassis design
I’m going to start cutting tube tomorrow and pretending everything ASAP.

The way I see it. if I can get the chassis together in a month I’m better off building a new one then trying to get the motor in this current chassis. Let’s see if I’m right.

21” betty height, 74” roof line with a possible 8” of up travel on the shocks
28” belly width, 50” rocker width, 54” arm bar width, 51” roof width
105”-109” Wheel base
Drop our belly for tranny servicing

Bare bones design no fancy work just light and quick to build .
This is the idea:





ok so progress from today...about 50% of the tubes precut







the skid plate's cut and dimpled. remember this will have a drop out belly that will allow you to pull a tranny without undoing the links.







and the lower suspension link mounts







i'm gonna run a batch of random brackets on the plasma table tomorrow.

spent 2 hours tonight on it and got some progress tonight.



here is the work space...a bit of a down size from what i've built in before.







I scotchbrighted the tubes before bending. got them bent, and notched the ends.





i'm amazed how long shit takes to do when you are trying to be extremly accurate because i'm prebending and notching with no fitting. shit should go faster then i can start to assemble and have something to fit to.

Why are you welding the plate in the subframe? If it's to support the skid plate you're adding very little strength. I built one buggy that didn't allow me pull the pan while the trans was in the car. I will never do that again, especially on something that will be used for racing.

That's a clean & simple chassis design. :cool2:

Looks like 1.75" tubing?

The skid is not done yet. The center will be removable for dripping the tranny...without removing the links.

The center strip of the skid is not welded in yet it's just placed there. I'm waitin on some tbe clamps to finish the drop out skid.



And yes 1.75" tube

how deep is the belly ?
looks like there is a bunch of foot room wasted with that tall of a belly .

mine is 7 inches from the bottom of the belly to the bottom of the floor where my feet are(just above the front drive shaft yoke). then the seat is raised up 4 inches for the tcase

Looks good Kris, and you could always add some footwells sunk into the floor if you got any spare room under there.
