Did the subs. have lift blocks in the rear from the factory? Mine has what looks like a 2in. block in the rear. It sits about like the others I see around.

I have never seen one that way. But hey, this is GM were talking about, they did all kinds of strange things./forums/images/icons/smile.gif

I'v been on, over and around 3 K-5's and 2 burbs..all in my driveway at once too,LOL.
I have never seen it..but like mike said and the saying goes...
Thats GM for ya!!/forums/images/icons/laugh.gif

I dont thing GM ever did, but I know Ford and Dodge has.

I don't think GM ever did. chances are someone put the block in to level out a sagging rear end, rather then replacing the springs like they should have.

Yep, GM DID use rear blocks on 4x4 Suburbans from 1955-1966! My 1960 GMC Sub 4x4 has a factory 5.5" rear block with a cast in lower shock mount. If yours is a 1978 then someone had put a block in there, not the factory.

Thanks for all the replys. This the best place I'v found for GM info.
