If your chassis is F44 package, your rear axle should also be a 1 ton axle. 3.73 gears normally. Mine is an 89' Sierra C1500 SLX with the F44 heavy duty frame package. I want to know if the front brake calipers and pads on your trucks are HD or regular duty? I had a hell of a time getting the correct brake pads and rotors, because of not knowing this. I'm not sure if all these trucks were supposed to have HD front ends, as well. But if theres a parts package to upgrade the front end, I'd love to do it. Everything else on my truck is HD/high capacity/large components even though it has a puny 305 lol which is soon to be swapped for a rebuilt 350. Hope this info helps and I hope you guys get back to me. PS- this is the BEST way to learn about these trucks, GM (archive) headquarters knows about as much as we all do HA!
