Wheelbase Stretches on 35s

I’m back on 35s and stretched out. I will have to remeasure because when I put in the 12” travel shocks this spring I had to shorten the rear arms a bit in order to get full stuff with the 60. I have a Genright tank and a four link out back. I purchased the axle, tank, corner armor and 4 link stuff all in a package years ago. I had also outboarded the rear shocks at that time as well but didn’t do a great job of it to be honest. The stretch tank and 4 link were fine but I was after max stretch over max flex so the outboarded shocks and uptravel were compromised. It helped the Jeep feel a whole lot more stable on climbs, and had a much better departure angle on drop offs since it was on 37s at the time. When I redid all the stuff this spring and was more concerned with uptravel than final wheelbase numbers I lost a little bit of the rear stretch I had but I also pushed the front as far as the steering would let me without doing a steering box relocation and got about 1.5” up front with everything staying happy. I actually just finished assembling a new set of rear control arms for the rear and will get them installed in the next day or two and I’ll take some measurements. I must not have used enough anti seize on the JJ ends as the lower end of my lower arms were rusted/frozen and no longer adjustable so after trying to break them free a few times, drilling small holes and filling them with PB Blaster, a torch and a 4’ cheater bar without luck. Then having to make adjustments the hard way with just one adjustable end. I just bought eight JJoints and some 2”x.25” wall DOM and built some new links an inch shorter than my old ones so I could get all the adjustments I need in. Once I get my Atlas tucked up a bit more and my belly pan raised up a little more I’ll be all set. These new shocks ride so much better. And once I dialed in the front arm geometry after my flop it climbs stable again. I know you will recognize the rock pile here.

i'm in the 108 -109" range i think. my rear drive shaft is over 32" long now.

why? wheelbase and wheel spread add stability and i wanted to challenge myself..

i rebuilt the whole back end of the frame narrower and higher, from the last body mount under the doors back.

I know @sjalkian did a 5" stretch using the Genright tank. He can jump in and fill out the details! ;)

I stretched the rear by 5”. I did so to gain more stability specifically on steep climbs and dropping off big boulders.

I got there by getting a Genright tank which allowed me to maintain 19.5 gallons and get 5” with my Dana 44. I took the opportunity to outboard the rear shocks and various other things that my build thread explains.

Did you/ do you plan to go bigger than 35? 108/109 seems a little long for 35s?

@SvtLdr made some towers for my coilovers. Got some locked off road hydro bumps, TMR limit straps,and some joints/DOM/small truss. The year previous I already moved to a small aluminum fuel tank in preparation for a stretch. Then of course went straight to a small hill and air’d it out 😂
