I'll start from the beginning and try to make it quick.

Picked this 88 Suburban up in november 2015 for $250 and planned on a small lift, 33s and a little crawlling here and there. The term 'snowball' comes next.

In January, I picked up an 89 for parts. I mainly wanted the wheels and tires, but it was cheap enough and spare parts are always a plus. My roommate and I swapped the suspension in the yard.

I soon came to realize, I needed lockers of some sort.

In November 2016, I decided I wanted a little more power. I pulled the engine from a 5 year project and put it in the suburban. The ECU couldn't make sense of the cam and noone makes a chip that could. I swapped it to carb and the fpr failed on me so I parked it.

While it was sitting, some friends and I decided to plan a trip to Moab in May. That gave me 6 months to get the suburban ready. I needed an engine, taller lift, bigger tires, winch, and lockers.

Ordered a Rough Country 4" lift with rear blocks, sold the blocks and used the ORD 4" shackle flip.

I decided to make use of the 02 Denali I had sitting in storage. It had a bad transmission and the interior was worn, but otherwise ran great.

Swapped the LQ4 into the suburban. I used the Trans Dapt mounts and conversion flexplate and spacer since I kept the 700r4. I had to move the engine mount frame brackets back about 1.5" to get the engine to line up with the trans. I also hit the stock crossmember with the corner of the oil pan, so I got the ORD hd crossmember.

While waiting for someone to modify the harness for me, I got bored and pulled out the cutting wheel. Took 8" out of each side of the core support.

To avoid any possible fitment issues with exhaust, I picked up some block huggers from Yearwood Performance since they had them in stock. Then I dug through my scraps and made the straight pipes work.

The guy that was suppose to be modifying my harness for almost a month finally got it back to me...untouched. I was a little intimidated to mess with it, but it had to be done. It wasn't pretty, but it worked. I plan to redo it later.

Getting the pedal mounted was fun.

Since it was finally running, I took it in to get tuned.
17493032_1603649692996590_3363369493767713840_o.jpg


Took it for a test drive. Me being the smart guy I am, I hadn't made a bracket to connect the TV cable yet... paid for the later.

Decided to repurpose the sliders from the ranger.

Made some bumpers. 1.75" .120 DOM, 1/4" and 1/8" plate.

Threw a spartan locker in the front and welded the rear.

This was a victory picture after getting all that done with just over a week left before the trip. Notice the ranger in some of the other pictures. We were working both at the same time.

Our trip to Moab started off well.

remember that TV cable bracket...yea...it worked, but I made it too late. The dyno and test drive without it were enough to start the failure and the drive to Moab was enough to finish it. Lost 2nd and 4th gear about 3/4 of the way there. We did wheel Fins-n-things the day after getting there. We started the trans swap the evening after Fins-n-things.

The 'new' trans had a sticky throttle valve so it didn't want to go into 4th. I spoke with Bowtie Overdrives and verified the pressures. They said I'd be good to go, so I kept wheeling.

This is when I realized I wasn't as prepared as I thought.

Got bound up and spit out a u-joint.

Luckily, one guy was there with a trailer and was nice enough to tow the suburban back to Albuquerque when he left, while I stayed and rode around in the ranger.

After Moab, I replaced the shaft, installed a reverse manual valve body in the trans and it sat while I was away for 2 months. That's when Chris and I decided to start the Youtube channel.

I decided to bob the rear when we were on Hells Revenge. I dragged the rear about 6' before the rear tires touched the wall in the devils hot tub.

Worked a trade with an old coworker for the axles off his Western Hauler conversion. D60 and D70HD were the next plan; along with 4 link, radius arms, coilovers and 37s.

Now I'm finishing the tube front and trying to decide if I want to make the front stock again, or dove nose.

Can you dove it and cut down the core support so it still retains the headlights?
 
hot damn, nice work dude! I love low and big tires, lots of great work. That bob work is niceee
 
The rear bob looks like you did a great job!
I vote for stock front end.
 
how much did you cut out of the rear?

That's how I did it before. I just cut an 8" section out of each side between the lights and body mounts, then welded the outer sections back on. With the tube front, I don't want to put any of the core support back so mounting the headlights will be a little tricky since they use a bucket.

how much did you cut out of the rear?
27" from the body.

Pretty cool like the look, almost as goofy as mine.
I took the side out of mine on Body Snatcher that's when it got narrowed in the back and shortened. Busted my window also so I was done with those.

I am still running the stock headlight buckets. I had all four in it for awhile but it was blocking a bit more air then I liked so took out the lower two.

If I were to do it again, I would go the route that you did, think it looks cool. As well as more weather friendly.
 
The weather won't make up it's mind yet, so I've been doing small things here and there.

Started re-routing the harness so I can mount the ecu inside and get rid of the large factory fuse block.

Drawing up some cage ideas. Took a trip to Phoenix this past weekend for the Offroad Expo and to pick up some tubing to build the cage.
30265265_2050457104982511_6741663439858434048_n.jpg


Picked up some PRP harnesses as well as about 60% of the parts to get this thing finished; now to get the time to do it.

Cage ideas.... Do one X that spans both the A and B seating area. No reason to do two little ones. Have the cage go beyond your third row, it may but the pictures don't show that.
 
It looks like that is probably all of the room he has to work with after bobbing...

Scroll up Keith :D

...
Your B to C sides need to be there you have two dead nodes and no support for them both in the middle.
After drawing these up, we drew more on the white board at work.
There will only be one X on the top.
The third row is no longer there. The termination point in the picture is just forward of where the body ends now.
I haven’t drawn anything for the side of the B to C hoops because we’re limited on space. I’m trying to keep the 2nd row seat functional for sitting and folding. Once we have the hoops in there, we can figure out the side supports.
 
Can you give a little more info on what you did for your DBW pedal? It looks like you bent and cut/welded it back together to get it straight? Any more pics or insight on that?

Cool burban BTW

I took the pedal from the Denali, drilled the bracket to mount in place of the stock suburban pedal. I cut the denali pedal at both ends (behind the pad and near the spring), positioned it where I wanted it and welded it back together. The only pics I have of it are above. I show the two pedal side by side, drilled, then the denali pedal mounted before and after cutting it.
My original plan was to just cut the pedal off near the spring and make my own, but I didn't have the parts I wanted to make it with at the time.

I've been slacking on the updates.

Part of the plan with the tube front was to get the ECU, fuse block and TAC module out of the engine bay and into the cab. I had to re-work the harness to get it to route into the cab. All that's left with the wiring is to finish the fuse block wiring and figure out where to mount the battery.

We also got everything we needed to build the front axle. Rebuild kit, Yukon grizzly locker, diff cover, hubs, chromoly axles, 35 spline outers, bronze king pin bushings, rotors, pads, wheel bearings and seals. The only things we didn't change were gears and king pins.
I think we spent as much time cleaning all the grease off the axle as we did setting up the gears. May have shed 5-10 pounds off the axle by doing so. lol
