Most Replaced Parts on the GMT900 HD Chevrolet Silverado 2500HD (2007-2014)

The Silverado 2500HD GMT900 ran from 2007-2014 and is LMM and LML Duramax years. After enough of these come across the parts counter you start to see the same short list of components over and over. Here is what owners of this generation actually end up buying, and what to know before you order.

Sensors, Cameras and Driver Assistance

The usual tell is a lane keep or forward collision system that reports as unavailable after a windshield replacement. Worth checking at the same time you rotate tires, since the wheel is already off.

Common parts in this group: park assist sensors, backup cameras, blind zone modules, front camera modules, radar sensors.

Worth knowing: TPMS sensors have to match the protocol and frequency the receiver expects.

Glass and Wipers

The usual tell is chattering or streaking that returns within a week of new blades. This is one of the items where a towing or work truck and a commuter diverge sharply.

Common parts in this group: wiper blades, wiper transmissions, wiper motors, washer pumps, rain sensors.

Worth knowing: Windshields with acoustic interlayer, HUD or camera brackets are not interchangeable with base glass.

Drivetrain and Transfer Case

The usual tell is vibration that appears above 55 mph and grows with speed. Heat is the accelerant on this one, which is why it shows up faster here than up north.

Common parts in this group: transfer case encoder motors, front differential actuators, u-joints, CV axles, driveshaft center bearings.

Worth knowing: Transfer case shift motors and encoders are matched to the specific case, and the module reads their position directly.

Exhaust and Emissions

The usual tell is an exhaust tick on cold start that quiets as the manifold expands. Mileage is a rough guide here. Load, heat and road surface matter more.

Common parts in this group: catalytic converters, oxygen sensors, DEF injectors, diesel particulate filters, EVAP purge valves.

Worth knowing: Diesel aftertreatment parts are tightly integrated with the calibration.

Cooling System

The usual tell is a temperature gauge that climbs in traffic and drops back on the highway. This is one of the items where a towing or work truck and a commuter diverge sharply.

Common parts in this group: radiators, water pumps, thermostats, coolant hoses, cooling fans.

Worth knowing: Surge tanks and caps are pressure-rated to the specific system, and a wrong cap is a slow way to cook a head gasket.

Filters and Fluids

The usual tell is an oil life monitor that reaches zero faster than it used to. Mileage is a rough guide here. Load, heat and road surface matter more.

Common parts in this group: oil filters, air filters, cabin air filters, fuel filters, transmission filters.

Worth knowing: Air filter media density affects the mass airflow reading, which is a fueling input.

Before You Order

Have the VIN ready. On a Silverado 2500HD the same model year can carry two or three different engines and several suspension packages.
Check the SPID label in the glove box or console for your RPO codes.
Front and rear parts are rarely the same number, even when they look identical.
If the part is electrical, confirm the fit before you order. Electrical parts are not returnable at any GM dealer, including us.

Shops and fleets can set up wholesale pricing at gmpartsclub.com/wholesale. Everyone else can start at our Chevrolet OEM parts catalog or search for Silverado 2500HD parts.
