T4 Timing Chain Sliding Rail - Middle - 2.8 VR6 (AES)

This timing chain middle sliding rail is a vital component in the Volkswagen VR6 timing chain system, designed to maintain precise engine timing and smooth, reliable operation. It is fitted to T4 Transporters with AES VR6 engines, as well as Golf Mk3, Corrado, and Vento models equipped with VR6 engines.

Positioned along the timing chain path, the middle sliding rail provides essential guidance and support, helping to control chain movement and maintain accurate valve timing. As VR6 engines age, the original sliding rails can wear, crack, or become brittle, leading to increased timing chain noise, accelerated wear of chains and sprockets, and potential timing inaccuracies.

Manufactured to high-quality standards, this replacement sliding rail restores correct chain control and is ideal for timing chain service work, preventative maintenance, or engine rebuilds.

Service Recommendation:
When replacing timing chain components, it is strongly advised to inspect all timing chains, tensioners, and sprockets for wear or damage and replace as necessary. During reassembly, ensure all moving parts are properly lubricated to promote smooth operation and long service life.
