GM Camshaft Roller – Silverado, Sierra, Tahoe, Yukon & Escalade (OEM 12629698)

A Camshaft Roller for GM's Full-Size Trucks and SUVs

This is a replacement camshaft roller cross-referenced to GM OE number 12629698, covering a wide range of Chevrolet, GMC, Cadillac, and Pontiac vehicles built on GM's full-size truck and SUV platforms through the late 2000s and early 2010s. If you're chasing a valvetrain tick, a lifter-related code, or you're doing a broader engine refresh and want to address the camshaft rollers while everything's apart, this is a direct OE-number match rather than a generic aftermarket substitute.

Where This Part Lives in the Engine

The camshaft roller rides against the camshaft lobe and translates its rotation into the lifting motion that opens and closes each valve, which means it's a part that's under constant load and friction every time the engine runs. GM's Vortec-era small-block V8 family powered this entire range of trucks and SUVs through these model years, and the rollers are one of the components that occasionally shows wear or failure well before the rest of the valvetrain, particularly on engines that have gone long stretches between oil changes.

Given how many model years and trims this OE number spans, it's worth confirming your specific engine against the part number on your old roller before ordering, especially on trucks that may have had an engine swap at some point in their history.

Signs a Camshaft Roller Needs Attention

A failing camshaft roller often shows up as a ticking or tapping noise from the top of the engine that doesn't go away as the engine warms up, sometimes accompanied by a lifter-related trouble code or a noticeable loss of power if a cylinder's valve timing is affected. Because these trucks and SUVs are commonly used for towing and hauling, valvetrain components on high-mileage examples tend to see more cumulative wear than the same engine in a lighter-duty application.

Why Owners Replace This Part

Most owners aren't chasing extra performance with a camshaft roller replacement — they're addressing a noise, a code, or doing a preventive fix while the engine is already apart for other valvetrain work. Because this part is cross-referenced directly to the OE number rather than sold as a generic substitute, it's a straightforward way to put the correct component back in without guessing at compatibility. That matters more than usual on an OE number spanning this many model years and brands, where a mismatched aftermarket substitute can end up close enough to fit but not quite right for long-term durability.

Installation Notes

Camshaft roller replacement on these engines typically means removing the intake manifold and valve covers to access the valvetrain, so budget time accordingly rather than treating it as a quick bolt-on job. It's worth inspecting the camshaft lobes themselves for scoring while everything is open, since a worn roller and a worn lobe often go hand in hand, and replacing only one while leaving the other damaged is a common reason this repair gets revisited sooner than it should.
