88-98 SAS Thread

OK so how about we make a compilation of information, and links (to sites and threads) on the good ole 1988-1998 (or the like) straight axle swap. If you post a link, then I will put it on this entry, and we will have a list of them. Pictures, measurements, prices, etc. Any other 88-98 "harcore" info other then SAS would be cool too.

I will start off with some...

Anymore?

PS I have learned that anything by willyswanter is "the shit"...

Can't wait to see it bro.

Some info (got from zkrawler). He used 52" front springs. The front hangers from a 79 3/4T GM (front hangers from front springs). The rear hanger is from the same truck (front hangers from rear springs). The front hangers are mounted flush with the front of the frame. The rear hanger spring eye is 51" from the front of the frame, and the bottom of the hanger is flush with the bottom of the frame. This puts the hanger almost at the end of the "boxing" in the frame.

Question: Anybody know if all 88-98's have the same distance from the rear of the frame to the center of the axle? If so, I have another question to follow up.

SAS doesn't show up. I searched for names I knew, and I have a lot of them on my favorites. 88-98 is a good search for it though...

If I read this correctly (and I read it twice) He used the FRONT HANGAR FROM THR REAR SPRINGS on the backside of the front springs and put the shackle in that? I had my springs under mine last night looking at things, and the shackle has to inboard of the frame ALOT to get the 31.5 center to center. Im using 53" Ferd springs but essentially it will be like his arrangement. If I can find a set of those factory mounts (that I can use) Id really like to do it that way for simplicity though. Was there any other spacing out or adjustments or did these just simply put the shackle were it needed to be?? Thats damn sweet/lucky if it does

Well, as I understood it, the hanger is all that is needed.... and yes you read it correctly. He put them on the inside of the frame pointing inward of course. I guess that's all he needed. I'm sure he will post up and tell us for sure though.


As you can see, he had to shave off some of the top of the hanger.

the only consideration with doing it with the rear spring perches from the rear of a donor truck is that they take a rear shackle. this is a problem with the use of stock chevy front springs. If you go the 52 inch rear springs, you already have 9/16" steel bushing and no width problems. Just pointing this out. Some might try to go stock length fronts from a 73 to 87 chevyand run into hole size and spacing problems with the perches from the front of a rear spring

That is a very good point to make. That will only work with Chevy rears as previously stated, as the front chevy springs have a smaller bolt out back.

i noticed a couple people mention using the stock front hangers front the front springs in their "stock" location on an 88-98 conversion. how does this work with the 52" springs up front?

do what? We use hangers off of 73-87 4wd trucks, and put them on the 88-98 frames... stock location? I don't get what you are saying. There are no spring hangers on a 88-98 front, when it's stock.

"stock" location, meaning where it was originally designed to go on a vehicle. ie front spring front hanger goes all the way out front, rear spring rear hanger goes all the way at the other end.

oh ok. so you are asking how the front spring hangers off of the front of another truck will work on the front of an 88-98? Hmm... seems like we answered that question already? I don't know, maybe it's just me though, but I could have sworn we already said that zkrawler is using them just like that....

ok, figured it was time for me to post up since my rig has brought up a few questions....as yall seen in the pic that american posted up of it the front rear spring hanger dost give you the 31.5" center to center measurement, but yes i takes a rear shackle, therefore rear springs, unles you fab your own shackles then you can solve that problem and run front springs if you want to, but with how great it works out usin the 52"s i would advise anybody to go that route.....as far as the front hangers i did use the ones off of the 79 and i mounted them flush with the end of the frame which put the eye about 1.5" from the end of the frame but i dont know the exact measurement because i havnt put a tape on it, and i mounted them flush with the outside of the frame as well wich keeps the 31.5" center to center measurements to match the chevy spring pads.....here's the pic of the front hangers btw i had to use shims because the front springs are wider then the rears so the front hangers were a little too wide
