High quality guide rail 11317533489 for BMW 7 series

This high-quality timing chain guide rail with OE number 11317533489 is specially matched for BMW 7 Series models. Produced strictly according to OEM technical standards, it can replace the original guide rail directly during engine maintenance without cutting, drilling or any secondary modification.

The guide rail adopts high-temperature resistant reinforced composite material with embedded metal skeleton, featuring low friction, outstanding wear resistance and strong anti-fatigue property. It limits the movement path of the timing chain stably during long-time engine operation, effectively solving abnormal rattling, chain deviation and chain jump risks caused by aging original guide rails, and keeps the valve timing accurate all the time. The optimized smooth contact surface reduces abrasion of the timing chain and prolongs the service life of the whole timing kit.

Precision injection molding ensures all mounting holes, radian and overall dimensions are fully consistent with original parts for tight assembly without gaps. Each finished guide rail passes strict dimensional inspection and appearance screening before delivery to avoid assembly mismatch.

It is a practical and reliable overhaul spare widely stocked by auto engine repair shops, suitable for all BMW 7 Series vehicles compatible with part reference 11317533489, effectively protecting the timing system and avoiding costly engine overhaul caused by timing breakdown.
