4x Camshafts Exhaust Intake for Mercedes

This set of four exhaust and intake camshafts is designed to restore valvetrain timing on the 4.6L and 4.7L V8 engines found in the Mercedes S550, Maybach S550, ML550, and GL550 from 2012 through 2017.

Overview

This four-piece exhaust and intake camshaft set gives you a complete valvetrain refresh for the twin-turbo V8 in the Mercedes S550 and related models. Each camshaft is machined to control valve lift and duration so the engine breathes and fires as intended. It is a strong choice for shops and owners rebuilding a worn top end on a 2012 to 2017 Mercedes V8.

Specs At A Glance

Good To Know

Q: Can these camshafts go in without replacing other valvetrain parts? A: They physically install like the originals, but on a rebuild it is smart to inspect lifters, followers, and timing components at the same time. Confirm the exact engine code before ordering.

Q: Do all four camshafts need to be replaced together? A: Replacing the full set keeps timing and wear matched across both cylinder banks. If only one cam is worn, a full set still gives the most predictable result.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
