Re: What year did GM change to IFS?
This gets kind of confusing because GM didn't convert them all over at the same time.
1988 was the first year for the 1/2 ton IFS trucks. All 1/2 ton trucks made that year were IFS.
1992 was the first year that the Blazers, Jimmys, and Suburbans were IFS. Also the first year that ALL of the 1 tons were IFS, making this the first year that GM only made IFS 4x4 trucks.
I think 1991 was the first year you could get IFS 1 tons and 3/4 tons, but I am not certain. Either 90 or 91 you could get 3/4 and 1 ton IFS trucks, but you could also still get them as the old style solid axle trucks.
