    Chevrolet Silverado HD — GMT800 (first-gen HD) (2001–2007)

    This is the heavy-duty Chevrolet Silverado, the 2500HD and 3500 trucks, 2001–2007: Heritage kits cover it as the Silverado HD (2001, 2002), the Silverado 2500 and 3500 (2003) and the Silverado 2500HD and 3500HD (2005), NICB's 2001 and 2003 VIN manuals list the full-size truck in 2500 (3/4 ton) and 3500 (1 ton) series, 4x2 and 4x4, with 8.1L gasoline and 6.6L diesel V8 engine lines, and GM's 2007 lists call the truck the Silverado Classic. Most rows come from GM's service RPO lists for the C Silverado 2WD and K Silverado 4WD (2001–2006) and the 2007 Silverado Classic 2WD and 4WD; these lists are word for word the GMC Sierra's of the same years (and in 2001 also the Suburban's, Tahoe's and Yukon's), the C and K lists are word for word each other's (the 2005 K list adds seven military LSSV codes), and the rows follow the Sierra HD GMT800 and Silverado GMT800 docs. The 2001–2004 lists cover the light- and heavy-duty trucks together, while the 2005–2007 lists print a separate heavy-duty half, the only half used here for those years (the 2005 2500HD and 3500HD order guides add UG1, NB8 and NC7); codes those lists print only in the light-duty half, P-metric tires, GVW ratings under 8,500 lb, the 4.3L V6 and the 3.08 axle are left to silverado-gmt800, utility-body items and codes whose wording names GMC, Cadillac or Pontiac are left out, and the kits' RPO lists and 2003 and 2005 order guides add years that GM's shorter 2002 list and some other years omit. The lists give the 6.0L LQ4 and 8.1L L18 gasoline V8s, the 5.7L L31 (2003–2007) and the Duramax 6.6L diesels LB7 (2001–2004), LLY (2004–2007) and LBZ (2006–2007); no listed source gives the truck's paint or interior trim codes beyond the paint scheme and special color codes.

In the 2005–2007 lists only the heavy-duty half (the half that prints the L18, ML6 and MT1 entries) is used.

Of 31 codes of this doc checked, 29 agree on the meaning (L18 LB7 LLY LBZ L31 MT1 MW3 M74 MW7 M96 KC4 KNP JH7 GT4 GT5 G80 C6P HVY Z82 V76 NP1 NP2 NP8 KL8 UG1 NB8 NC7 K05 UY2), one disagrees (ML6, worded as a New Venture Gear 120 mm manual; the GM lists give the ZF) and one was not found (PTO). L31 is worded there as a Mexico export engine, Z82 as a Reese-type hitch package and G80 as Positraction limited slip; JH7 is 12,000 lb, the 2001 list's reading. No block or error was met.
