Restore smooth valve train operation, eliminate top-end engine ticking noises, and maintain maximum combustion efficiency with this 100% Toyota Original Engine Valve Roller Rocker Arm (Part Numbers: 13801-0E010 / 13801-0E012). Engineered as a Toyota original direct mechanical replacement for high-torque common-rail turbo diesel engines, this precision-crafted component transfers camshaft lobe movement directly to your intake and exhaust valves with minimal friction.

Unlike cheap aftermarket rocker arms that suffer from weak needle bearings, soft roller surfaces that wear down rapidly, or poor oil flow channels, this Toyota original component is precision-forged from premium hardened alloy steel. It features an advanced internal roller bearing assembly that effortlessly handles the extreme pressures and intense heat cycles of 1GD-FTV and 2GD-FTV engines, preventing catastrophic valve train failure.

This valve train roller rocker arm fits perfectly inside the cylinder head of the following vehicle models running 1GD and 2GD turbo diesel engines:

A worn-out, loose, or damaged valve rocker arm will cause highly annoying metal ticking or tapping noises from the top of your engine block, leading to sluggish acceleration, rough idling, and lost horsepower because the engine valves cannot open fully. If a low-quality generic aftermarket rocker arm snaps completely while you are driving at highway speeds, it can throw off engine timing entirely, drop a valve into the cylinder block, and cause catastrophic piston-to-valve collision damage that destroys the whole engine. This Toyota original 13801-0E010 / 13801-0E012 rocker arm guarantees maximum mechanical strength, rock-solid structural durability, and absolute peace of mind for your hard-working truck.
