Browse 2007 GMC Engines by Model

Pick your 2007 GMC model to see exact fitments in stock. 2007 is the GMT800→GMT900 changeover year — many trucks and SUVs were built in both the "classic" (creased-door) and "new" (smooth-door) body styles, and the 8th VIN digit decides the engine code. Not sure which one fits? Text us your VIN and a specialist confirms the match.

Why Buy a 2007 GMC Engine from Auto Power Source

Every 2007 GMC engine in our inventory is pulled from an inventory-verified donor vehicle, cataloged by VIN, and held in our warehouse pending sale. Each unit goes through our six-step inspection — VIN-matching, compression testing, noise & smoke verification, full visual inspection, multi-angle photography, and palletized shipping. 2007 was the GMT800-to-GMT900 changeover, so the same model can carry either a "classic" (creased-door) or "new" (smooth-door) body — from the 5.3L and 6.0L small-blocks to the 8.1L Vortec 8100 big-block and the 6.6L LBZ/LMM Duramax, we match the engine code and body style to your truck before anything ships.

Our certified technicians compression-test every cylinder and run a leak-down evaluation before any 2007 GMC engine is cleared for sale. You pay a fraction of dealer-new pricing for the same GM engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get up to a 3-year warranty plus 30-day money-back. Not sure whether your truck runs the classic 5.3L L59 / LM7 or the new LMG, LC9, or LY5? Text your VIN and we will confirm.

Your 2007 GMC Engine Options: Compared

Most 2007 GMC owners face four real choices when their engine fails:

← Swipe sideways to see all columns →
Option Cost Reliability Warranty Fitment Match
Used OEM (this collection) $$$ Best Value High Up to 3 years VIN-matched
New OEM (dealer) $$$$$ 2-4× more High Manufacturer Exact
Aftermarket / Reman $$$$ Varies 6-12 mo May adapt
Junkyard $ Cheapest Unknown None DIY

Tested used OEM hits the sweet spot — same GM engineering as new, fraction of the cost.

2007 GMC Engine Buying Guide

  1. Read the 8th VIN digit. On a 2007 GMC the 5.3L alone splits into classic L59 (VIN Z), LM7 (VIN T), L33 (VIN B) and new LMG (VIN 0), LC9 (VIN 3), LY5 (VIN J), LH6 (VIN M) — same displacement, different engine code.
  2. Classic vs new body style. 2007 sold both the GMT800 "classic" (creased door skin) and GMT900 "new" (smooth door skin) Sierra and Sierra Denali — engine mounts and accessories differ, so match the body style as well as the engine code.
  3. Gas vs Duramax on 2500/3500. Sierra HD and Savana 2500/3500 ship with 6.0L LQ4 / LY6 gas, the 8.1L L18 Vortec 8100 big-block (final year 2007), or the 6.6L LBZ / LMM Duramax turbodiesel (VIN D / 6) — completely different engines.
  4. Watch the Denali special. The 2007 Sierra Denali / Yukon Denali use the 6.2L L92 (VIN 8) high-output small-block — it does not swap with a standard 5.3L or 6.0L unit.
  5. Always run the donor VIN if available. We provide it on request for any engine in our inventory to verify mileage and history.

Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.

Our 6-Step Inspection & Shipping Process

Every 2007 GMC engine we ship has been through these six steps:

1. VIN-Matching
We match the donor VIN to your VIN to confirm engine code, emissions calibration, and drivetrain fit.
2. Tested & Verified
Certified technicians compression-test every cylinder and run a leak-down evaluation on each engine.
3. Noise & Smoke Verification
Units are run to verify normal mechanical sound and clean operation — catches wear static tests miss.
4. Visual Inspection
Every accessible component is inspected: manifolds, valve covers, accessories, sensor harnesses, turbo on Duramax units.
5. Photograph & Catalog
Multi-angle photos sent to you BEFORE we ship, for your approval.
6. Palletize & Ship
Strapped on a heavy-duty wooden pallet, shipped via freight at no charge.
