Product Description
Core Selling Points
Fast-turnover timing wearable part for combined one-stop purchasing
Timing chain guide rails are high-failure components on BMW N62 V8 engines. Under long-term high-speed friction with timing chain, continuous high-temperature oil mist erosion, engine vibration and cyclic tension extrusion, the original guide rail’s wear-resistant plastic sliding surface will wear thin, peel off, crack and deform.
Failed tension guide will lead to loose timing chain, abnormal rattling/rumbling noise inside the engine during idle and acceleration, deviation of valve timing, engine jitter, power drop, increased fuel consumption; in severe cases, the chain jumps teeth, which will directly scratch pistons and valves and cause engine scrapping.
Most buyers purchase this right tension rail together with left guide rails, timing chain, hydraulic tensioners, seal gaskets as a full set in one order to cut procurement and logistics costs, bringing stable profit margins and low inventory risks for dealers all year round.
100% OE identical precision dimension, direct bolt-on installation without modification
Strictly manufactured in accordance with BMW original factory technical standards: overall curved radian, mounting hole position, sliding track radian, thickness of wear-resistant layer, fixed buckle structure are fully consistent with genuine 11317533462.
No cutting, trimming, bending or timing calibration adjustment is required after replacement. It perfectly fits the N62 engine cylinder head timing chamber, cooperates with the timing tensioner to keep the chain always in proper tension state, greatly shortening engine timing disassembly and maintenance working hours.
For vehicles produced before December 2004, it needs to be used together with upgraded guide rail 11317533479 for matching installation.

Installation Position: Right Bank (Cylinders 1-4) Timing Chain Tension Guide Rail
Reinforced Durable Structural Design
- High-strength reinforced PA66 nylon main bracket: Added glass fiber for reinforcement, anti-deformation, anti-cracking, resistant to long-term high-temperature engine oil erosion
- Imported ultra-wear-resistant PTFE sliding lining: Low friction coefficient, wear resistance far superior to ordinary plastic materials, effectively reduce timing chain running noise, prolong service life
- Integrated injection molding overall structure: No degumming or peeling between bracket and sliding layer under long-term reciprocating tension
- Standard reserved mounting holes, firm fixation after tightening bolts, no shaking or displacement caused by engine vibration
- Complete finished product without extra accessories needed, ready for direct assembly
Stabilize Timing System & Thoroughly Protect V8 Engine
- Cooperate with hydraulic timing tensioner to continuously apply moderate tension to the timing chain, prevent chain loosening, jumping teeth and falling off
- Limit the running track of the timing chain, reduce swing and friction noise during operation, eliminate abnormal engine rattling sound
- Guarantee accurate valve opening/closing timing, stabilize idle speed, restore original power output and fuel economy
- Avoid severe engine collision damage caused by timing failure, greatly reduce major overhaul risks
Fully Resolve Typical Guide Rail Failure Faults
- Obvious rattling, humming abnormal noise from engine front timing cover
- Engine idle rough, periodic jitter during acceleration
- Vehicle power attenuation, climbing and overtaking powerless
- Fuel consumption rises significantly, exhaust emission deteriorates
- Timing chain elongation accelerated, frequent timing fault codes triggered
- Hidden danger of chain jumping teeth leading to engine permanent damage
