Okay - so what in the heck do all of you guys want wheel tubs for?

Is there something I should know about - do I need them too?

 

[RGV72BLAZER]

classified information sorry...lol

When/if you start to see crescent shaped shiny spots inside your existing rear wheel wells......you will be ready to join the fun.

Yep definately one of smarter things I did to the Jimmy. Its easy to remember because I only do a few smart things.

The body shop put two sets together for me. They do something to the edge so that on one it is depressed dowon and the other operlaps and weld it and when done it is smooth across. I added 6 inches to each side. So no rubbing even under full stuff.

Ah - well luckily my Blazer only wheels at the mall - so no worries about that

 

[Ryan B.]

Yah but you gotta watch out for those double stacked curbs at the mall! Almost flops you over if you don't have enough flex.. i had to winch off the big curbs over at the great mall of milpitas.


Greg, your rear wheels actually rub the inside of the wheel tubs?
I don't think mine have ever rubbed, even with the 38's but that could because of my 8" rear springs. My k5 isn't exactly a ramp queen. I could see if you 4 link it and the axle walks side to side when you flex like crazy "tubbing" yer k5 would be a good idea.
...or just hack out the whole bed all together and be done with it.

vtblazer, maybe you can beat up greg for the other set of wheel tubs.

Ryan,

A couple of points on this photo:

• Rear tire is NOT touching inner tub. This is a result of a couple of things:

Wheel backspacing
​

Stiffer rear springs than up front
​

• The body is also NOT level at full flex. My current hypothesis is that the stiffer rear springs are causing the body to lean....(if the springs won't let the wheel move UP, then the whole body will lift instead). What I need to do is find a spring for the rear that has a very low spring rate like my fronts (Something like 250 lbs/in).

Going to a longer and softer rear spring will keep the body level, and will allow that rear axle to move up into the wheelwell a LOT more. Keeping the body more level will help minimize the "spooky off-camber feeling" on obstacles too. I figure something like a 56" (or 57"?) spring might be a closer match for F/R spring rate.

Once all that happens...... wheeltubs had better already be "customized". I will start by trying it on the '72 (Stomper) and then apply lessons learned to the '69K5 when the time comes....

Yeah, that's my intent...

Let him get them back east, go down for a 'visit', then...dayum, how'd they get in my truck?

They use a flange tool

Not only is the body leaning but flexing too.. Lack of Cage.
With my recent blazer buildup the whole 2" DOM cage is tied into the frame and sliders...
With such a stronger more rigid cage... Whoa dude, where'd my flex go? I lost quite a bit of flex.. we forklifted it before and after.

Even with a bad ass coilover suspension like wally, i don't think you can ever get the body LEVEL at full flex going up an RTI ramp.. seems like its always gonna lean to one side or the other when your flexing unless you're on an obstacle where the front and rear happen to be flexing in opposite directions. ?
Now maybe this is where your helicopter gyroscope and airbags come in...
