Hi Anjwhalen, you are correct in identifying this Jeep as being built by Dave Doetsch, me! I built it for the 2009 SEMA show, on behalf of TeraFlex Suspensions. It was nicknamed "SIKJEEP".
I have several videos of this Jeep featured on my YouTube page at DoetschConcepts - YouTube
. Also just Google image my name and "Jeep" to see more photos of it.
The suspension was a TeraFlex 6" LCG long-arm along with a 1" Daystar body lift. Tires were 40x15.50R20 Nitto Mud Grapplers on 20x10 RBP Wheels. Fender flares were Xenon flat panel and the doors are Body Armor tube doors. Front bumper was the Poison Spyder Brawler with a Warn 9.5ti winch, as well as Poison Spyder Rocker Knocker rock rails. It also had a Rock Hard 4x4 roll cage and a Power Tank CO2 air system on the back.
Back in 2009 not many people ran 40" tires, so that in combination with needing something over the top for SEMA, we had more than enough lift than was really neccessary. Today, you can realistically run 40" tires with a combination of a quality 4" lift, flat fender flares a little pinch seam trimming. Sure there are other ways (less lift, more cutting or other body mods) in order to get the 40s to fit, but my option is a proven way that I have experience with.
Good luck with your build!
