Ok - just a thought... when you checked frame clearance with the tires on, was the front end up? In other words, if the front tires, suspension, whatever is removed and the front of the frame is layin on the ground, how close is the back of the frame?

The reason I asked the earlier question, is in the above pic (if I am looking at it right) the left side of the pic is the front of the truck. And it looks like the frame clearance is increasing as you go left in the pic.

I'm currently running the 14" stock rims with 195/75's. This is a 25.5" OD. Although I want to run a 26" OD wheel. 18" 225/40's... I set the notches up and bag brackets up for a 26" OD, but this 25.5" still does'nt even come close!

So, immortal, lol. I don't really know how to interpret your last post. Can you re-word that again? I don't understand what you are asking?

When I took measurements, I pulled it out onto the road in front of the driveway. So, I don't think it was a problem of whether or not the truck was sitting funny and or uneven surface to measure from.

Yes, this is because the trucks rear is only laid out. The front is still stock. Although, if your thoughts are that it will lay when the front is laid out, I don't see how that could be plausible.

IMO, the rear should lay regardless of the fronts position. Right before the frame rail kicks up in the back, you can see it in the pic, should be a pivot point and that should be touching the ground!

Ok, With the front and back of my daughters truck layed out, the frame sits flat on the ground. If I were to put a block of wood between the axel and the notch while the truck is layed out, then raised the front all the way up, it would lift the entire frame off the ground because the pivot point is the rear axel, not the part of the frame that is at the back of the cab.

Make sense?

What I am getting at is if your math were all correct, then you should have enough clearance. The angled rear bag mount might be messing things up some, but it shouldn't be 2+ inches worth.

So what you are saying is that it is possible that I'm not laying out because of the front?

Thats what I'm getting out of it when you say that... What does your daughters truck look like when the front is up and the rear down?

This took a little doing... but hopefully the end result will save you some $...




The above pics are with 0 psi in the front and back bags. There is approximately 1.5" clearance between the notch and the axel (about the thickness of a 2x4).

2x4 installed on both sides....


Back of frame has about 2.5" clearance, front has about 6.5" clearance. 0 psi in the rear bags (2x4 between notch and axel), and about 100 psi in the front bags

I think this pic is pretty close to the one you posted. Hope this all helps and I for one DO NOT think you have a hacked rear setup.

Also FYI, her truck is also running 225/40R-18 tires. Can't remember how deep you notch is. Hope this helps.

Wow, can't believe it took 8 pages to get to this point. Again, I think you did WAY more research than most other 4 link setups. Can't remember what your measurement was for the notch, but figured compairing pics would be worth a 1,000 words.


Now if I visualize things correctly, on 225/40R 18's you might need an additional 1/2" clearance. Now the question is, can you raise the bottom of the notch 1/2" without lowering the structural integrety of the frame at that point? Would certianly save a but load of frame work.

But I will not profess to be a structural engineer

WOW! Immortal you rock man! I appreciate your effort!

I'm kind of feeling a little more relieved when I see these pics! If this is all true, then all I really need to do is just fix the link bars!

BTW, only said hacked rear end cause of all these problems, lol! But I guess I'm too harsh on myself?

Your daughter is running a 26" OD wheel then too...

Yea, and me and dev were talking about notching out the notch and he was concerned with structural integrity too. I want to go this route if need be too cause it would save gobbs of work! But I'd rather do it right...

See I was under the impression that the rear should lay out despite the fact if the front is up or down.

What would happen if you took out the 2x4 and did it?

OH! And...

Yea, its kinda hard to find out of 166 images! LOL!

See with my math, this should be PLENTY of axle clearance... This should allow about 1.5" more clearance when laid out on a 26" OD. So if your daughters is 6" notch, I either might get lucky and bottom out on the notch when completely laid out or will have to notch some... yea, like a 1/2" lol...
