Used Duramax LM2 3.0L for Sale — VIN-Verified.
Powerstroke, Duramax & Cummins — VIN-verified, tested diesels for Houston trucks, shipped right the first time. 0% restocking, ever.
Used & remanufactured Duramax LM2 3.0L — VIN-verified, tested, and shipped nationwide from our Pasadena, TX facility. Fits Silverado/Sierra 1500, Tahoe, Suburban (2020-2022).
The LM2 is GM's 3.0L inline-six turbodiesel with EGR/DPF/SCR (DEF), and it differs from the updated LZ0 that followed — so we VIN-verify which one your truck needs. We inspect the fuel system, crankshaft/belt-in-oil components, and check for known sensor issues. Tested before we quote, long-block or complete clearly stated. Ultra Auto Parts TX is Houston's drivetrain specialist for used and remanufactured diesel engines, serving Pasadena, Deer Park, Baytown, La Porte, Channelview and the wider Gulf Coast truck market from our shop at 5041 Spencer Hwy, Ste 101, Pasadena, TX 77505. In a region built on work trucks, fleets and towing, we focus on the three diesel platforms Texans actually run — Ford Power Stroke, GM Duramax and Dodge/Ram Cummins — and match every long block or complete engine to your exact VIN before it ships. Unlike a general salvage yard, we treat diesels as core drivetrain, not random inventory. Every used diesel engine is VIN-verified against your truck's year, cab and emissions configuration, then inspected and tested before we quote a firm price. We speak English and Spanish, respond within 10 minutes during business hours, and back every diesel with a real warranty — so Houston owner-operators and shops buy with confidence.
Known issues we check on the Duramax LM2 3.0L
The 2020-2022 LM2 inline-six runs EGR, DPF, and SCR with DEF, and it differs from the later LZ0, so we confirm you get the right generation. We inspect the fuel system and sensors, and we check for the belt-in-oil wear this design can develop over time. Because these are newer, low-mileage cores matter, and every LM2 is VIN-matched to your Silverado, Sierra, Tahoe, or Suburban. Drivetrain units are tested in Pasadena before we quote you.
Used vs. remanufactured Duramax LM2 3.0L — which to buy
A tested used LM2 is a smart value since this engine is recent and clean cores are available, and ours are inspected for belt-in-oil and sensor condition. Remanufactured is worth considering if your vehicle is climbing in miles and you want the fuel system and wear items addressed with a longer warranty. We carry both and match to your budget. Send your VIN and we will steer you to the right LM2 for your GM vehicle.
Why buy a quality used diesel engines?
A diesel is the most expensive component in the truck, and a proper machine-shop overhaul often runs $8,000–$15,000+ once you add gaskets, injectors, machine work and labor. A quality tested used engine or a reman built to OEM spec gets you back on the road faster, at a fraction of that cost, with a warranty covering the assembly — not a shop's one-off labor guarantee. For a work truck losing money every day it's down, verified used or reman is usually the smarter math.
Common signs you need a replacement
We know these platforms cold: 6.0L Power Stroke head-gasket and stretched-head-bolt failures, EGR and oil-cooler issues; 6.4L Power Stroke cracked pistons; LB7 Duramax injector failures and later LLY overheating; Cummins 5.9L (12v/24v) VP44 and lift-pump issues, 6.7L DPF/EGR and injector wear; and high-mileage blowby on all three. We inspect for exactly these before quoting.
