Sas On A Gmt800 Info

sc4808 · April 13, 2010

I don't know how many Hardcore OffRoad guys (or girls) that we have on here, but I just thought I would pass along some info.

I have been looking to do a Solid Axle Swap on a couple of my trucks, the problem has always been that it is very easy to do if you go with Leaf springs in the front, there are several companys that offer these kits that are fairly inexpensive and easy to install, of course you have to provide your on Axle and springs, but all of the fabrication is done for you. I however would prefer to go with a CoilOver 4 link suspension instead, both for Ride quality and Articulation, but no one makes a 4 link coilover SAS kit for the 1/2 ton GMT800's, OffRoad Unlimited, Pure Performance and Offroad Direct make such a kit for the HD's but not the 1/2 tons.

OffRoad Direct has just came to market with a new 4 Link Coilover kit for the 88-98 1/2 ton trucks, but have no plans to create a kit for the GMT800's. With that being said, I feel like the 88-98 kit will be a good starting point for the GMT800 platform with mostly Crossmember fabrication needed as the main difference.

I am still a little ways out on this project, seeing that I am working out of state right now, it will be late summer before I get to start on it. Plenty of time to pull everything together.

I will probably use a Dana 60 under the front, but I have not ruled out a rear 14 bolt converted to a steering axle, this was on Extreme 4x4 a couple of months ago and looked pretty good, that would give me 14 bolts front and rear, that would be cool.

Which vehicle(s) would you be doing this swap on? That's a big job to do for the average shade tree mechanic (assuming you are one). Keep us posted if you go through with it, lots of pics too!

I run 4 links front and rear on my jeep...... nothing beats them for side to side axle height travel. Homemade thou..... DOM tube and QS Components HIEM joints. This is the HIEM joints I used. I have about 6 or so years on the 4link system..... NO PROBLEMS as of yet with them... or any piece of the system I made.

The first one that I will be doing it to will be the 1995 K1500, it presently has a 6" IFS lift and has had as big as 38's on it at one time, right now I have it on 35's due to the fact that thats about as big as the front end can stand. The reason I will do this one first is due to the fact that OffRoad Direct offers a 4 link kit for those trucks.

Next in the order would be the 03 Sierra, that one will require some fabrication. If it goes well, I will more than likely do the 06.

I have been a Jeep guy for most of my life, my first one was a CJ5 that I drove during my high school years, I have just in the last 10 years or so started the move to Fullsize rigs, most of my OffRoad driving is Mud due to where I live, I do love trail riding and am looking forward to doing some wheeling while I am in Washington State working, also I will be stopping by Moab on the way home. I have been avoiding the SAS because I don't want Leaf Springs up front, but a 4 link I can live with.
