T4,T5 Timing Chain Sliding Rail - Lower - VR6 (AES,AMV,BDL)

This timing chain sliding rail is designed to ensure precise engine timing and smooth, reliable operation on a wide range of Volkswagen VR6, V6, and V5 engines. It is fitted to T4 and T5 Transporters, as well as Golf Mk3 and Mk4 models and related platforms using these engines.

The sliding rail is located at the bottom crankshaft sprocket, where it provides essential guidance and support to the timing chain as it runs between the crankshaft and camshaft assemblies. Its role is to maintain correct chain alignment, reduce vibration, and minimise chain slap. A worn or damaged rail can lead to excessive chain noise, inaccurate valve timing, accelerated wear to the chain and sprockets, and in severe cases, catastrophic engine failure.

Manufactured to precise tolerances from durable, wear-resistant material, this replacement sliding rail restores correct timing chain control and is ideal for engine rebuilds, timing chain service work, or preventative maintenance on higher-mileage VR6 engines.

For best results, this rail should be replaced as part of a complete timing chain service, especially if timing chain noise is present.
