2007 Chevy Silverado 2500HD LS 4x4 CCSB - Specs and tech Data


This information is unashamedly all about my particular truck. Much of the information will also be applicable to many other trucks, even if they aren't the exact same year, model, configuration, or trim level as my truck. I can't, however, cover all the info and options for all trucks, even just the 07's or just the 2500HD's. If you need more specific information about a different truck, see the "references" section at the end of this article.

My truck is officially known as:

2007 Chevrolet Silverado (Classic) 2500HD (K25743) LS Crew Cab Standard Box 4WD 1SK Package

That's quite a mouthful of a name! It breaks down like this:

2007 Chevrolet Silverado - Year, make, and model (obvious!)
(Classic) - Denotes the older body style of the two versions of Silverado that were produced as 2007 models.
2500HD - Chevy's notation for Heavy Duty 3/4 ton pickup truck
(K25743) - GM model number for Crew Cab Standard Bed 2500HD 4x4
LS - The trim level (LS is the mid-level, between Base and LT)
Crew Cab - Four full doors
Standard Box - The box is 6'6" ( a short-box is 5'8" and a long-box is 8' long)
4WD - Four Wheel Drive
1SK Package - sub-set of the trim level, denotes a standardized set of options.

The line of trucks to which my truck belongs is known as the GMT800 series. Covering 1999-2007 they are also more commonly known as NBS, or "New Body Style", trucks. Of course, now that the Silverado has been redesigned for 2007.5+ (the GMT900 series trucks) it becomes less convenient to refer to the 99-07 trucks as NBS, unless we want to call the 2007.5+ trucks NNBS!

The most useful information I made into a little graphic card I printed, laminated, and keep in the glove box. It beats digging through the 600-page owners manual for information.

Load label for the factory-installed trailer hitch. Notice also the 7-pin wiring diagram moulded into the cover - nice touch.

GVWR sticker applied to driver's door jamb.

Sticker gives GVWR, GAWR - front, and GAWR - rear information, along with tire size, rim size, and tire pressure information.

Inside the glove box is this decal that gives camper loading information, for use with slide-in campers.

RPO Codes

GM uses a 3-digit code, called an RPO (an acronym for Regular Production Option), to identify the options with which a specific vehicle is built. They are listed on a label or sticker called the Service Parts Identification (SPID) label. On late-model GM trucks this label is found inside the glove box. Some of the most famous RPO's are Z28 (performance package found on Camaro's) and LS1 (specific type of V8 engine).

By recording your RPO's and looking them up in a reference table you can identify the options with which your vehicle was built.

Most RPO's can be found in the following:

  The Service Parts Identification (SPID) label found in my truck. This label includes other information along with the list of RPO's, including the V.I.N., wheelbase, paint codes, and vehicle model number.

Below is a file I made listing all my trucks RPO's and their de-codes, available in:
