Ok crazy maybe but want a 3500 SRW, But Have a 1993 GMC K2500HD with the 6.5 4.10 gears 14BFF 10.5 axle. What Components would i need to make this truck a 3500 rating?

Pretty sure you would need the 11.5 rear end, overload springs, and heavier torsion bars, I may be missing something though.

i actually meant like convert a 93 k2500 to a 93 k3500 sorta conversion, not to the newer one

For the rear end, it looks like you have a 14B so that's I believe the same as a 3500 unless they used a Dana 70, but I think that may be some duallys only.

Suspension, I think it's only the helper springs (level load springs).

Frame, I'm not sure on that one.

what about the t bars

Hmmmmm, that's another good question. Maybe call your local GMC dealership and see if the pn's match for your 2500 and a 3500 same year, if not ask the parts guy if there is a load rating on them. Just a thought and it only takes a phone call.
