Original BMW Slide Rail for Timing Chain, BMW 128i, 228i, 328i, 335i, 428i, 528i, 640i, M3, M4, X3, X5, and Z4 (2006–2021)

This Original BMW slide rail is a 92 g timing chain guide for the N20, N26, N51, N52, N55, and S55 engines in BMW cars and X models built from 2006 to 2021. The rail gives the timing chain a low-friction surface to run against, which keeps the chain on its path between the crankshaft and camshaft sprockets. BMW started production of this version in March 2010. It replaces the earlier 11-31-7-584-651, and BMW lists it as exchangeable retrospectively, so the new rail also fits engines built before 2010. Each rail is sold individually.

Original BMW Parts carry a 24-month parts warranty.

BMW's parts data shows the same rail across a wide range of engines. If your engine has the 584-651 rail, this number takes its place.
