1972 Chevy 4wd Longhorn Project: Never Ending Changes

[Dieselwrencher]

Today it was pretty nice out other than the wind is crazy! I decided I wanted to put my other wheels on and see how it looks. If I have the extra money, I think I'm going to put DRW hubs on to move the rear wheels in some. But then I'll have to run disc brakes and they seem to be big $$$ for D80's. So, it might have to be the way it is for now.




They are M/T Baja A/T 305/60 18s on M/T classic II's.

one way of doing it without the emergency setup is use front disks and calipers of a 1977 K20 the hole in that disk is big enough to fit on the back of the dually hub with longer wheelstuds
you need to make youre own plates for the calipers and weld those on the axle
if you want emergency brakes you need to find rearbrake calipers of a certan caddilac ... think it was an el dorado those have mecanical handbrakes build in
i myself found the rebuild calipers for those but its hard to find the bolt on handbrake lever thingy
theres a howtoo on the dana 70 / 14 bolt http://www.pirate4x4.com/tech/billav...b_disc_brakes/

Thanks whatyaknow. I knew about the chevy rotors and such. But there are 2 problems with them. 1 the chevy rotor hub center needs to be machined out a lot to fit on a d80 hub and when you take them that far it makes the chevy rotors prone to cracking. 2nd, I'm not sold on the cadillac single piston calipers being up to the tasks I'm going to ask this truck to do. I may leave it as is for now.

I'm also thinkng about going air ride 4 link in the rear since I have to add traction bars. I'll be half way there on a 4 link and I already have some air bags. We shall see where it goes.

Hey now, that sounds like a keen idea!

what bags are you looking at? i'm sure we have the opportunity for many good discussions on this front. at some time in the future(and it may not be to far since i cannot quit thinking about it) i will be designing a bunch of dana 80 and 72 chevy link mounts and bag mounts.

Looks great to me Ryan!

I like the steel wheels better. Those are a little too close to being "ethnic" for me.

LMAO! I like the steel wheels too, but getting the hub caps on and off without scratching the wheels or damaging the caps is a PITA! These wheels will look better when I wear these tires out and get 325/80 18s some day when I have the pesos laying around.

[doubleb's69]

Looks great. I also like the steelies but know the hassle you speak of.

[gerfunken]

The truck is looking great!

[ryanroo]

That looks awesome! and if you find yourself leaning back towards the steelies, id gladly take those M/Ts off your hands. that was just the brand of ethnic i was looking for. (BTW, you can fit big brakes now...) i may go with 17" black steel just to save some coin for the first go round, but i know exactly what black aluminum 18"s i want

Yeah, I did this twice and I knew it was going to be a PITA.

Thanks. From that angle I can see my front axle needs to go forward some. I thought it did, but with these you can really see it. Yeah, the big discs may have to wait. All the rear disc with e brake inside them, parts around here are dumb expensive. The front might not be bad to do though.

What about late model Dodge wheels?

They bring more than what I want to pay for used wheels and they're 17s. Those tires are pricey in the size I'd want.

The 2500HD wheels aren't bad looking on these trucks.

But I already have ethnic wheels.

I have a 2002 Dodge at the shop that I put a Kelderman kit on last fall. It will take some time to make the brackets, but it's well worth it in the end. I can post pics of that set up. it utilizes the spring and shackle hangers too. The shackle hangers were a mount for each air bags's ping tank. The front spring hangers are where the top link hooked in, and then you add a lower link bracket ahead of the spring hanger. I have wanted to do this for a while and now might just be the time. That dodge rides so nice it isn't believable.

i'd look at pictures! ill have to use all custom bracketry but i like to see where i can rob ideas. personally i think they use too short of links, but i suppose that is the rock buggy stuff coming out in me. i am also curious how you determine the size need for the ping tanks. also i wonder if they are neccesary for a lighter truck with large bags. it would seem that most regular road bumps wouldnt move the axle enough to make it matter with a larger bag.

What is the difference in the drw vs the srw? is the housing different, or is it just the WMS of the hub located farther in? i know a dually has more hub sticking out but ive never been able to find out if it has a different housing as well. or really any definitive WMS-WMS dimension. i know my RC60F is somewhere around 69.5-70" and i think the 80 is 70"

Ryan

the flange on the drw hub sits farther in compared to the srw so it moves the wheel closer to the diff

there 4 different widths for the chevy 14 bolt those can be made by 2 different axlewidths and the 2 different types hubs , to make a chassis cab dually axle for instance you need a single wheel axle with dually hubs

[ryanroo]

I am pretty familiar with the GM 14 bolt stuff. ive been bleeding GM since i was old enough to walk . Ryan and i both have dodge dana 80s in our trucks, and the information is not nearly as easy to find on these weirdo axles and usually seems to be in conflict from one source to the next.

[watahyahknow]

wherent the newer dodge axles allready fitted with diskbrakes ?
if so it shouldnt be too hard to upgrade the older style ....... just googled it they do and they started in 2001 .......

googled some more the hubs for the newer axles seem to be different , maibe the disks and calipers fit though

[1985-GMC]

The only thing about those is the parking brakes always suck.

That and the super duty d80s are a metric bolt pattern so these rotors won't swap over. And they had a lot of problems with these calipers sticking.

hmmmmm oh whell looks like its going to cost yah then , i wonder if those aftermarket brakes are any better if it comes to sticking , theres a LOT of water being sucked in back there when its raining

[ryanroo]

Gm's were sticky too. and the pbrake sucked. my HD was always eating rear pads. every time i pulled the calipers i cleaned the slides and doped them generously with copper anti-sieze and they still always sucked. i was on my 3rd or 4th set of rear pads to my 1st set on the front. rear disks are just tempermental.
