Ok, I've been planning and doing the math for the sas on my 1997 c2500. My plan is to use a late model (2005) ford super dana 60 (heavy a$$ axle, auto locking hubs, dual piston brakes). Utilizing the factory coil spring pockets on my truck for the coils, and utilizing the ford factory radius arm mounts on the axle for a clean stock looking swap. The issue i have right now is the factory spring pockets on the truck are approximately 36-37". Must of what i read about leaf spring swaps tend to have a 39-40" spread (outside frame rail mounts). Would there be a stability issue with the mounts this close on the axle?? could it possibly be solved by putting in a stiff sway bar? and mounting the shocks wide on the axle? This is going to be my first SAS so i want to have my bases covered. Any other issues y'all think i might run into with this type of setup?

I thought the perch spacing on the leaf spring axles are 36" and the mounts are INSIDE frame. If you use the Ford Super Duty spring buckets, I dont see why you'd have problems. Use the tracbar as well. Check out Fullsizebronco.com....look at the SAS forums. Also check out Pirate4x4 in the Chevy forums. Good luck.

The factory ford buckets on the axle are about 42" apart so no bueno. Also, That would make more sense, if they are 36" then i just fab some new buckets and weld on the axle and good to go. Ill check them out.

Mine is a D44
I’m not a build thread kinda guy... never stay motivated enough.
I seen those axles a lot at PNP
I decided against spending a week modifying it.
Odds are you’d need to make a truss and link on top of that as well as build new buckets.
Mine is just a D44 and she’s been good to me.
