1994 K2500 Suburban SAS – 08 Super Duty 60

Good Morning PBB! I recently returned from a deployment with the California Air National Guard and my two oldest boys, 7 and 9 years old, and I started the first phase of our Suburban build. My family has had this truck for nearly 20 years and I am excited about diving in to this transformation. It has served as my stepdad’s daily driver, grocery getter, and lake camping and boat towing rig. It has served us well and I have always liked this truck.

The truck is a 1994 ¾ ton Suburban. Drivetrain wise, it has a 454, 4L80E, NP241C, 14 BFF and a 9.25” IFS front axle. Other than aftermarket wheels, running boards, a brush guard, and stereo the truck is basically stock.




Below is the plan for the first phase of the build:

Replace the front axle with a Dana 60 from a 2008 F350 that I acquired from LKQ Online (great deal BTW).



Replace front suspension with a WFO Concepts radius arm setup and King 2.5x10 coil overs.

Rear shackle flip with ORD shackle mounts, zero rates, and U-Bolt Reversal kit. I am still trying to figure out the rear shock plan. Ideally, I would like to use 2.5 King remote reservoir/piggy back shocks but I have to figure out mounting options. Any suggestions???




37x12.5x17 Maxxis Razr tires on cheap steel wheels with 4.25” backspace that I got from National Tire and Wheel.




Regear both axles to either 4.56 or 4.88. I did a calculator to determine what ratio would be “near stock” and the result was 4.33. That seems like it isn’t low enough for the added weight. I am open to suggestion on this one.

Pull engine and transmission to replace all leaking seals and clean 26 years’ worth of road grime from the frame and drivetrain.

The goal of the build is to be a family adventure rig. I always enjoyed camping as a kid and my boys enjoy it as well. We recently added our fourth boy to the family and now we don’t fit in my ¾ ton Dodge which is where this Suburban fits in. After serving us so well when I was a kid, it will continue to do so for my kids. I am also a member of a local four-wheel drive club. The club consists primarily of Jeeps but they welcome all makes/models and while the Suburban isn’t much smaller than my Dodge, its paint isn’t nearly as nice. So, in addition to camping, the Suburban will also be our main off-road rig tackling trails and proving to the Jeep guys that us fool sized rigs can party too.

If anyone has suggestions on gears and how I could mount the rear shocks, please chime in!

This is where we left off yesterday after finding my garage again and helping my young boys turn wrenches:

Looking forward to seeing this build.

Rear shocks are a pain in the ass. I decided I'll be re configuring them to OJ Bronco-style with both in front of the axle on account of the tight clearances inside the rear shock towers.

usanumber1, you mentioned that previously when we talked on another forum. Now that I am home, I have been looking at the bottom of my rig to see how you might do that. Are you planning to weld tabs onto the factory crossmember with the body mounts on it? If not, how are you planning on doing that?

Looking at mine, it almost looked like I could make a plate with tabs welded on that would bolt on in place of the factory t-bar. Something like this:



If I did that and ordered shocks with a reservoir parallel to the bolt, I think I could make it work. Then the shocks would essentially mount factory style. Any thoughts on that idea?

Today, I lost my little helpers to their first day of school; which was ok as I had a task today that required more cussing than I like them to hear. Unfortunately, I wasn’t able to make a ton of progress as some of my shop equipment, such as jacks and jack stands, were borrowed by my brother during my absence. That said, I did get the running boards removed and pulled the fuel tank skid plate off.

Those running boards did not want to come off and most of the hardware broke but the funny thing is, it looks like I gave it a lift already!



Also, before I got ahead of myself, I grabbed some measurements to use
