Is it a crew cab?

GMT400 definition is.....

The generation of trucks following the square body. Generally 88-98, except crew cabs which ran 92-00, and 3500HD which continued through the 02 model year.

GMT800 definition is.....

The generation following the 400, ran 98-06 with the exceptions noted above, and the fact that an 07 classic (basically a leftover 06) was available.

Asking questions is how we all learn!

Long story short, most truck production switched to the GMT800 ('99-'06) platform in '99 but GMT400s (typically '88-'98) were still available through 2000 in some applications (and sometimes special order only).

If it's the old body style, it's a GMT400. It may be beneficial for you to look up parts for a '98, as many parts sources will think you're looking for GMT800 parts if you tell them it's a 2000.

Yes, crew cab long bed

Thanks, that clears it up. So I could say I have a Y2K OBS GMT400 ??

Perfect, that clears up my parts searching. 1998 from now on.

You could indeed.

Sometimes it also helps when getting parts, to have the VIN ( vehicle identification number, in lower left corner of the windshield, on the dashboard). Engine type can be important too, even if you think it's not something engine related. Another determining factor on the 400 series trucks is they will have the 5.0(305),5.7(350), or 7.4(454) engine size( unless it's a diesel, then 6.5). The newer generation GMT 800 series, the gas engines are 4.8,5.3 or 6.0( all LS motors). Of course the V6 is a 4.3, but there's differences between the two series on them.

1st gen Escalades, '99/'00 are 400's. Basically a re-badged Denali.
Aren't the 2500/3500 99/'00(>'02HD) 400's referred to by GM as '400 Classic'?

99 classic, is a 1/2 ton, GMT 400. The 2500 and 3500 didn't do the GMT 800 body style until 2001 I think. I had a coworker with a 2000 4 door 2500, it was a GMT 400. He had to ask for parts for a 98.

Yes, the C/K 2500/3500 trucks were made until 2000, but those were not referred to as "classic," that I'm aware of. Simply C2500, C3500, K2500, K3500. They also dropped the "Silverado" trim, I think in 1999, when the GMT 800 "Silverado" came out...Confused yet? The previous Silverado trim on the GMT 400 got replaced with "LS" on the little cab sticker.

The "3500HD", (19.5" rims, heavy beasts) technically also a GMT400, were made until 2002.

I have a 2000 K3500 LS CCLB SRW (GMT 400) and a 1999 Silverado 1500 ECSB LS 2wd (NBS, GMT800). I always have to explain to my son, who is 9, why the "newer" truck looks older than the "older" truck, LOL.

I think some of the confusion comes from folks calling their trucks "Silverado" instead of C/K____ at the parts counter. And it probably doesn't help that the guys behind the counter can't tell one from the other on their screens. Every website on parts that I've come across is spot on if you know this difference. These transitions years for GM trucks are always confusing, as new body trucks roll out and the older generation of trucks are still being made simultaneously. Trim and name changes doesn't help, LOL.

Example: Going into the parts store and telling the counter guy you need a starter for a "1999 Silverado 2500", when your truck is a "1999 C2500" (Silverado-trim?) is guaranteed you will get the wrong part.

At least GM never made a 7 lug truck like Ford F-250!

Here again,use the VIN for parts...as long as your truck is stock this should help a lot.
