URO 11-31-7-574-397 Timing Chain Guide Rail BMW N52 N53 N54

The URO 11-31-7-574-397 Timing Chain Rail is an aftermarket replacement guide rail designed to maintain proper timing chain alignment and tension in BMW engines. This rail works in conjunction with the timing chain tensioner and other guide components to reduce chain slap, minimize wear, and ensure accurate valve timing throughout the engine's operating life.

Manufactured to match OEM specifications, this guide rail is a direct-fit replacement for worn or damaged original equipment. The timing chain rail is a critical component in the valve train assembly — a cracked, worn, or broken rail can lead to timing chain noise, erratic engine behavior, or, in severe cases, catastrophic engine damage.
