High quality tension guide rail 11317533483 for BMW 7 Series

This high-quality timing chain tension guide rail with OE part number 11317533483 is customized for BMW 7 Series. Manufactured rigorously in line with OEM technical specifications, it can directly replace the original component during engine maintenance, with no cutting, drilling or secondary modification required.

Constructed with high-temperature resistant reinforced composite material and built-in metal reinforcing frame, the tension guide rail boasts low friction coefficient, superior wear resistance and excellent anti-fatigue performance. Cooperating perfectly with the timing chain tensioner, it maintains the timing chain at a constant proper tightness during long-time engine operation. It effectively eliminates common faults induced by aged original rails, including loose chain, abnormal rattling, chain offset and jump-tooth hazards, and keeps precise valve timing to prevent severe engine damage from timing system failure. The polished contact surface lessens friction loss of the timing chain and extends the service cycle of the whole timing assembly.

Precision injection molding ensures all mounting holes, curved radian and overall dimensions are fully identical to OEM parts for seamless, gap-free installation. Every finished guide rail undergoes strict dimensional verification and appearance inspection before shipment to rule out assembly mismatching issues.

Recognized as a dependable overhaul spare part by numerous engine repair workshops, this tension guide rail fits all BMW 7 Series vehicles compatible with part reference 11317533483, providing stable and reliable protection for the engine timing system.
