What size tires on that thing Joesjunk - looks awesome!
That's a 1/2 ton???

Re: stock 4x4 pics...anyone?
 

Its a 3/4ton. It has 235/85/16 tires on it.

Re: stock 4x4 pics...anyone?
 

Of the two 4x4's I have this is as far as I got going for the sorta stock look. The other one is just a pile of parts, lol. Been spending my truck money on the panel for now. Maybe someday I will have a finished 4x4. :rolleyes:

Re: stock 4x4 pics...anyone?
 

Stock looking is what I'm after.
I have a full set of stock 15 in rims (I'm a 1/2 ton) from a mid to late 70s truck. You need these if you have front disk brakes. The rims on are the shop floor waiting for extra money before I send them to the sand blaster then paint them white to match my front and rear (rear not installed) stock bumpers.

Last night at Wal*Mart I picked up a pair of driving lights. They will be fitted to stock 71-72 front turn signals then put in my 71-72 bumper.

Like I said, stock looking. But I would like a few features.

I have a full set of original, 4x4 hubcaps like mothertrucker424 and a set from the rims I have, mid to late 70s. I'm thinking I'll have the mid 70s ones on there so WHEN they get ripped off I won't feel too bad. I'll keep the originals for any shows I may have to go to.

BTW, the 235/75R15s I have on there are the closest thing to stock height I could find. The speedo is dead nuts on with a GPS.

Re: stock 4x4 pics...anyone?
 

Awesome trucks guys. That is the direction that I want to take mine in - but really want to put a 3/4 Ton chassis under it:rolleyes:
but that costs too much $$ right now.

Other than those God-Awful Wheels and Tires this thing is stock (well the motor was changed @ one point...but that doesn't really count)
I think the tall skinnier tires look better on a stock heigh 4x4 than the wide tires do (maybe it it was a lifted truck I could see the wide tires - but they don't really do anything for me)

Re: stock 4x4 pics...anyone?
 

Blazerman, is your truck the GM503 Light Green?? Is there a glove box sticker???
Thanks

Cool truck ya have by the way!!!:cool:

Re: stock 4x4 pics...anyone?
 

I agree. Both my 72 3/4 tons have 16.5" wheels and there is little to no sizes for that size rim anymore. And the ones they do have are pricey. So I went to the junkyard and pulled 4 16" wheels off an eighties 3/4 or 1 ton ford van. They're pretty wide although now I forget how wide and the chevy hubcaps fit perfectly. The lug nuts were bigger so the factory lug wrench didn't fit, but luckily the van in the yard still had its factory lug wrench laying in the back. Much beefier than my original one. I have 265/70 16 mounted and I could definitely go wider thanks to the rim being wider. Nothing is out past the fenderwells either. If you don't mind using ford parts, it's a nice option.

Here is mine on a set of 285/75/16's

Re: stock 4x4 pics...anyone?
 

Mark,
That truck looks great...nice moutain background. It looks like it belongs there and the "deep" wheels are tough.
Let's put a stock chrome rear bumper on it.

Re: stock 4x4 pics...anyone?
 

Frank, I agree Marks truck looks awesome. Quite a settting in the background. Makes me want to grab a truck, camera and tank of fuel and head to the hills. We have lots of vine maple turning colors in the cascades right now and would make nice backdrop. Still working out the kinks in current daily driver.

Re: stock 4x4 pics...anyone?
 

Hey Blazerman,

What color code is it???

Re: stock 4x4 pics...anyone?

Re: stock 4x4 pics...anyone?
 

all you guys that have 4x4s - is a 1/2 ton chassis the same as a 3/4ton? - iIm going to keep asking till I'm blue in the face, but I keep getting "yes" and "no" so which is it?

I would like to tow a 7K GVW car trailer regularly - would the 1/2ton chassis be enough?? or should I put 3/4 Ton axles on it - or am I just being dumb?

Anybody tow with thier 4x4?

Re: stock 4x4 pics...anyone?
 

arkracing - The Chevy restoration packet shows there is a difference in the 10 and 20 frames. My packet does not give info on the 30 frames. The section modulus varies between each. I find the following definition: The section modulus largely determines the flexural strength of a beam of given material.

What I think that means is that the frame's ability to flex must be different and that affects the overall strength of the frame.

The packet gives the following frame info for the C and K series:

C10 (Except Suburban Carryalls) 39,000-lb-test steel; section modulus 2.98

K10 (except Suburban Carryalls) 39,000-lb-test steel; section modulus 2.70 (KS-KE107 models; 3.48 (KS-KE109 models)

C10 Suburban Carryalls 39,000-lb-test steel; section modulus 2.98

K10 Suburban Carryalls 39,000-lb-test steel; section modulus 2.70 (KS-KE107 models; 3.48 (KS-KE109 models)

C20 (Except Suburban Carryalls) 39,000-lb-test steel. All models except Longhorn: section modulus 3.71. Longhorn: section modulus 5.05

K20 (Except Suburban Carryalls) 39,000-lb-test steel; section modulus 3.48

C20 Suburban Carryalls 39,000-lb-test steel; section modulus 3.71

K20 Suburban Carryalls 39,000-lb-test steel; section modulus 3.48

Re: stock 4x4 pics...anyone?
 

Very nice. Perfect tire size too. I like it.

Re: stock 4x4 pics...anyone?
 

Thanks. I know you posted something like that in my other thread just less detailed. Thanks for taking the time to put that information up:) :) :metal:

I still have no idea what a "section modulus" is - it appears that K20 and K10 (KS-KE109 Models) are the same. (well the parenthesis are a little confusing - but I'm interpreting it that way)

How do I find out if mine is a KS-KE 109 or a KS-KE 107?

What the heck Googled "Section Modulus" and came up with:

section modulus (′sek·shən ′mäj·ə·ləs)
(mechanics) The ratio of the moment of inertia of the cross section of a beam undergoing flexure to the greatest distance of an element of the beam from the neutral axis.

Re: stock 4x4 pics...anyone?
 

its stock except for rims and 4" lift(like some of the other trucks pictured).

Re: stock 4x4 pics...anyone?
 

The packet says the KS107 is the 115" wheel base (SWB) and the KS109 is the 127" wheel base (LWB).

Re: stock 4x4 pics...anyone?
 

Then according to that information the K-10 LWB and the K-20 (Always LWB) are the same chassis.

Or am I missing something?

Re: stock 4x4 pics...anyone?
 

Sure looks like it. Someone with an engineering background might jump in and give some insight into what the above info means - it may not be very significant in the real world - I just know that are the numbers the packet gives. I definitely don't know what they really mean.

Re: stock 4x4 pics...anyone?
 

Yukon Jack - just out of curiosity: is that top one supposed to read like this - I think you're just missing a Parentheses??

K10 (except Suburban Carryalls) 39,000-lb-test steel; section modulus - 2.70 (KS-KE107 models); 3.48 (KS-KE109 models)
??

Well if they are the same then that makes me Happy:)

Oh and sorry for the HiJack - back to the pictures!!!!!!!!

Re: stock 4x4 pics...anyone?
 

I had a course in Mechanics of Materials last semster, which is basically calculating stresses and strains in deformable bodies (beams, pipes, columns, ect), along with deformation, ect. I don't remember going over it, but I cracked open my book from the class and this is what it says:

S = I/c, where:
S = Section Modulus
I = Moment of Inertia
c = Distance from Neutral Axis (center of gravity) to edge of beam

The section modulus is used then to calculate the maximum stress in any section of a beam using the formula:

Max Stress = -Mr/S, where:
M = Resisting Moment. This is the moment (think a rotational force, like a torque applied) that is resisting the forces applied to a beam. If you had a steel beam solidly attached to a wall, where the beam is free at one end, and hung a weight from it, the resisting moment would be the torque needed at the attached end of the beam to resist the force of the weight of the beam and the added weight, and keep the beam from ripping out of the wall.

It also says that the section modulus becomes larger if the shape of the beam is altered to concentrate more of the area as far as possible from the neutral axis (center of gravity). This could include raising the height of the "C" channel, making it wider, or having a frame with thicker horizontial sections than vertical sections. I'd assume that the frame is "taller" than a C-10 frame, but every C-20 I've seen has had a frame that looks identical to my C-10. The frame could be wider, that is my guess for the difference.

So, what does all of that mean? The larger the section modulus, the smaller the maximum stress in the beam caused by the weigth of the truck and whatever cargo or trailer is being carried/towed. So, a larger section modulus causes a beam (or frame in this case) to be able to safetly carry larger loads without deforming or breaking.

In this case, increasing the section modulus from 2.7 to 3.48 would decrease the maximum stress felt in the beam/frame by 22.4%.

NICE! this board is great!!!

Re: stock 4x4 pics...anyone?
 

Yep, I missed the parentheses.

here's my ride on 33s, they were junk so I have 31s and late model Chevy 15x8 steelies. I too am looking for some tall skinny tires for the stock look, like 34x9.5 if that exists. It's not lifted but it sits higher than a 71 K10 a guy I know has and he has 33s I think.
