LFD's 4dr Tahoe Build

[Big Block]

You are a sheet metal god. I'm in awe of your talent and creativity. Good work. I could only dream of doing something like that.

Yep that would be the same one.

That's cool to see him grow up in the different projects. Hope he sticks with it as he grows up.

So once my Wife came home I had some time to go out and play abit. I got the rear end of my "6 link" bars finished up and was able to mock up one side to make sure it lined up with the stock C4 Mono leaf link, and it does

I also got the rear mount for the Diff made and installed but I still have a bit of welding to do once I pull it back out. Then it is off to get a run over the surface plate to make sure I won't get any leaks down the road. You can see the spacer I Tig'd to the out side of the diff mount and I have done this to all link mounts for added strength as well as to take up the extra 3/8" of length in the shoulder bolts I have.

Great build, I'm subscribed. I'm putting a C4 IRS in my truck soon. Did you do anything to the aluminum parts on your irs to clean them up? In the pictures they look bright and clean. Do you plan to leave them as is or paint them with your new diff cover? How about the the ABS sensors do you have any plans to do away with them or just leave them.

The diff is just how I got it from the dismantlers, no cleaning. I will have the diff cover powdered coated near chrome to blend in a bit better and I will just remove the ABS parts.

Those turned out great! Are you going to put bushings or another mechanism on the end-links (between components) in case the suspension ever unloads?

I was thinking the same thing as you Mike. The Vett's don't use anything but I was still thinking of using a piece of Hydro rubber hose about 1/8" longer then my ID opening between mounts.

Now for the fun part I get to spend most of tonight with the Plasma making all my parts and pieces for the other side so it all matches and still add 1 or 2 gussets to this rear mount. I hope to have my Re8's soon so I can start mocking up placement and ratios and see what is left for the shock placement.

Can you share what sizes you are using for the Hiem joints for the track locater? Are they 5/8x5/8" and is the tubing 1" ID? I'm about to order the supplies for my IRS and I wondered what you went with.

I have not ordered mine yet. I will be calling in the morning to see what will work best for my set up.

If you are doing this in a truck I would use the stock rear diff cover and just raise the frame 4" and use the stock set up for the track. I only went through this in order to keep the rear floor as low as I could for the rear seat my wife wanted.

Kevin,

Do you need a slam bag rs8 for mock up I have three in my garage and one is damaged to use for mock up welding purposes!

Well I think for sure today was the hardest day of this build so far, but I got it. I was working on the front 4 link bars for the C4 and had a heck of a time in trying to keep the bars low and still maintain the smallest amount of front to back wheel travel during the full range of up and down wheel travel. I started out with equal length bars and had them parallel to the frame and that gave me over 1 1/2" of front to back wheel travel through the 10" of travel. After allot of different set ups and allot of thinking I ended up with 30" top bars and 31 1/4" lower bars. They are parallel to the ground at ride height and during the full 10" of travel my front to back movement is less then 3/8" total. I have it set up for the wheel to be centered in the wheel well at full dump and at ride height it is back 5/16".

Here are a few shots with the laser set up for checking the final configuration. First shot is full stuff and the laser is dead center of the hub Axel nut. Next is ride height and a close up of the tape. Then the last hub shot is at full lift and it is once again perfectly centered. I still need to play with my track bars abit because I am getting a few degrees of tow change during full travel and I think I can get it all out with some more work. If I can get it to zero it will also decrees the 5/16" number a very small amount.

So in order to make it all work I had to bring the top bars into the floor by 2". This really won't be a problem because my seat mounts are just above this and will still allow for a sheet metal cover over the seat mounts and top bars and the seat will still lay forward and down flat like it should. I will make some simple covers to go over the bars but leave access for the bolt to be removed. The upper bar has to have a down ward bend to it in order to clear the rear floor step structure and also to keep the bar below the magic 2" floor #. I will bend this bar in my hydro bender but first I will sleeve the inside of the 1 1/4" tube with a .120 wall 1" on the inside then if I feel it is needed I will add a gusset blade to the bottom of the tube.

The lower links are parallel to the ground at ride height and are angled in to the frame about 3"+- at the leading end of the bars to minimize the front to back travel of the hub during the up and down travel. I have 10" of travel 5" each way from ride height and that should have the frame 1" off the ground with a 31" tall tire and 6" of frame clearance at ride height.

I am still holding you to the CHEVROLET lettering across the back !

I will keep tabs on your progress.

I am thinking about using the tail lights off a 66-67 Nova. They are a touch wider and will Sit flat on the body and not pock out like the stock ones do.

Thats fine but then I get to hold you to sending me a good section out of a step or fleet gate for the lettering

Ummm...backpedaling quietly.

Thought you said you had one upstairs you were going to use?

Everything looks great BTW.

Find a couple of old beat up gates and stitch parts of each together to read C H E R V O L E T

That's one thing I wish I had done to my suburban when I redid the back. I'll probably end up making one of the aluminum tailgate bands work. One thing to keep in mind when you do this is the curve of the burb tailgate is pretty substantial. Lay a straight edge up to it and you'll see what I'm talking about.

[VA72C10]

Or, check with NWD02...he's putting in a panel with the older chevrolet script so he might be willing to hook you up with the original letters. I have a gate that the letters are pretty good on but the bottom's rotten that I could cut out the letters for you...but shipping would probably kill the deal for you.

All the one's in the attic are gone. My last one was cut up to match a dash I had for a project. See pic below

The section I will add would be just bigger than the letters so it should still blend in well.

I will just hit the pic-n-pull for another section. That is what I did for this gate. Notice it is a step side section put into a GMC gate.
