Genuine Mercedes 117-050-16-16 Timing Chain Guide Rail

The Genuine Mercedes 117-050-16-16 timing chain guide rail (also sold as a timing chain slide rail or chain guide) is an original equipment replacement part for Mercedes-Benz V8 engines. It keeps the timing chain running along its correct path, so the camshaft and crankshaft stay in sync.

Key Features:

• Genuine Mercedes-Benz part, made to factory specifications
• Mounts on the side of the chain opposite the chain tensioner
• Guides the timing chain and limits chain whip and wear
• Also referenced as 1170501616, A1170501616, 117 050 16 16 and 117.050.16.16

Guide rails wear and become brittle with age and heat. Replacing a worn rail helps protect the timing chain, sprockets and valvetrain. Replace it as part of a timing chain service for the most reliable repair.
