    GMC Sierra HD — GMT900 (HD) (2007–2014)

    This is the heavy-duty GMC Sierra of the GMT900 generation, 2007–2014: NICB's 2012 VIN manual lists the Sierra SLE, SLT and Denali in 3/4 ton and 1 ton series, and NICB's 2014 manual lists the 2014 Sierra HD in 2500 and 3500 series as Work Truck/Fleet/Base, SLE, SLT and Denali. The 2007–2009 rows come from the heavy-duty half of GM's service RPO lists for the new-body Sierra 2WD (the 4WD and Denali lists of each year are word for word the same, and all of them are word for word the Chevrolet Silverado's lists), codes those lists print only in the light-duty half are left to sierra-gmt900, and the 2014 rows come from GM's fleet order guides for the Sierra 2500HD and 3500HD; no listed source covers 2010–2013, so no row claims those years. The 2007–2008 heavy-duty halves print the same powertrain codes as GM's 2007 Sierra Classic heavy-duty list (L18, LQ4, L31, LBZ, MT1, MW3) with the LMM diesel where that list has the LLY and no ML6; L18 (8.1L, ended with the Classic), L31 (5.7L) and LBZ (the Classic Duramax, replaced by the LMM already listed) are left to sierra-hd-gmt800, and the MT1, MW3, NP1, NP2 and NP8 rows are marked disputed as a possible Classic carryover; the 2009 list prints the LY6 and LMM with the MYD and MW7 automatics, and the 2014 guides print the L96, the LC8 (2500 only) and the LML. Shared codes follow the merged Sierra GMT900 doc's wording; in Notes, "only in" names the series or body whose guide prints the code.

Each list prints a heavy-duty half first (the half with the LMM entry: lines 3–202 in 2007, 3–204 in 2008, 3–226 in 2009) and a light-duty half after it; only the heavy-duty half is used. The 2009 list's closing color and trim block follows the light-duty half and is not used.

    • NICB VIN manuals: docs/reference/nicb/nicb2012-gm.txt p.160-161 (Sierra SLE, SLT and Denali in 3/4 ton and 1 ton series), nicb2014-gm.txt p.152-153 (Sierra HD lines and badges) (T4, context only).
    • https://en.wikipedia.org/wiki/GMC_Sierra (2026-10-14; the GMT900 section names no engines or transmissions, so it neither confirms nor rules out the 2007–2008 powertrain codes).
    • Firecrawl search "site:gmauthority.com 2013 GMC Sierra HD RPO" (2026-10-14, through the shared gmauthority.com throttle; one request, no block, login wall or CAPTCHA): it found only the 2013 Sierra 1500 and Silverado articles, no heavy-duty article, so no GM Authority row is used.
