What Years???????
 

:gmc:
Can someone tell me what years the Suburbans were basically the same. Ex: 88-91 Is there a series of years that these ran like like that??

I know that most parts fit from 1988-98 depending on model. The pickup is exactly the same (for the most part) from 88-94.

you might try that question on this site:

I found some nice articles on this site as well.

if you happen to be looking for that unique front end then it's 89-91 . DAVE

73-91 were all the same design basis with slight exterior refinements in the early 80's (front clip was made a little more aerodynamic), and the interior quality improved overall every year.

92-99 are the same basic design with grille and side mirrors changing in 94 and a total revamp of the interior in 95 with the new Vortec engines.

Hope this helps.

Didnt the vortecs come out in 96?

well the bodys were the same 73-91 exept for front end , round single lights in 73-80,stacked lights 82-87 the dbl lights 88-91, fuel injection in 87. but all the parts will interchange...the new body stlye in 92 had the same motor,interior changed in 95 but same tbi motor and no air bag,96 was first yr of vortec and also air bag for driver only then both in 97 i think hope this helps...Steve
