12629698 Engine Camshaft – Hydraulic Roller Camshaft for GM Trucks and SUVs

This 12629698 camshaft is a replacement hydraulic roller engine camshaft that cross-references GM part number 12629698. It is listed for a range of 2007–2013 GM trucks and SUVs, including the Chevrolet Silverado and Tahoe, GMC Sierra and Yukon, Cadillac Escalade and the Pontiac G8. As shown in the product photos, the camshaft is about 500 mm long with a 55 mm front journal. Easy Life Markets sells it as a single camshaft for engine rebuilds and camshaft replacement.

The supplier's original listing called this a "camshaft roller". It is a camshaft designed for roller lifters, not a separate roller part. We have corrected the name so it is clear what you are buying.

What the Camshaft Does

In these pushrod V8 engines, the camshaft sits in the engine block and is driven by the timing chain. Its lobes push on roller lifters, which move the pushrods and rocker arms to open the valves. A worn lobe or a failed lifter reduces valve lift on that cylinder, causing ticking, misfires and a loss of power.

Cadillac Escalade, 2009–2013
Chevrolet Avalanche, 2007–2008
Chevrolet Silverado 1500, 2007–2013

These vehicles were offered with several V8 engines, and GM used different camshafts depending on the engine and whether it has cylinder deactivation. Many parts catalogues list 12629698 for specific 6.0L V8 applications. The listing does not name the engine, so please check the GM part number on your camshaft or in your parts catalogue before ordering.

Installation Notes

Replacing a camshaft in a V8 is major engine work. It normally involves removing the front of the engine, the timing chain and all lifters. Professional installation is strongly recommended. Points to keep in mind:

Replace the lifters when fitting a new camshaft. Old lifters wear to the old cam and can damage the new one.
Coat the lobes and journals with camshaft assembly lube.
Inspect the timing chain, sprockets and tensioner, and replace if worn.
Line up the timing marks exactly and follow the manufacturer's torque specifications.
If your engine has cylinder deactivation, make sure the lifters you use match that system.

Finding the Cause

Camshaft wear on these engines is often linked to a lifter failure. If a lifter has collapsed or its roller has seized, the matching lobe can wear quickly. Clean the oil pan and pickup screen thoroughly, and check oil pressure, to make sure debris does not damage the new camshaft.

Choosing the Right Lifters

A new camshaft should always be fitted with new lifters. On engines with cylinder deactivation, some lifter positions use special deactivation lifters, while the others use standard lifters. Make sure you use the correct type for each position, together with the matching lifter guides. Using worn or incorrect lifters can quickly damage a new camshaft and lead to noise or misfires.

Who This Camshaft Is For

This 12629698 camshaft suits engine rebuilders, independent workshops working on GM trucks and SUVs, and experienced owners who have confirmed the part number for their engine. Because the job involves the timing chain and all of the lifters, most owners have it fitted by a professional mechanic.

Common Questions
