Popular Timing Chain Guide Rail 2760 5201 00 for Mercedes-Benz -

Product Specification

This market-favored timing chain guide rail is manufactured per OEM specification part number 276 052 01 00, produced with a precise 1:1 original mold for Mercedes-Benz vehicles equipped with M276 3.0L / 3.5L / 3.0T V6 gasoline engines.
It is an indispensable wear-resistant component of the engine timing assembly, mounted next to the timing chain to limit excessive chain swing, absorb vibration noise, maintain consistent chain tension, and prevent dangerous timing chain jump or derailment under high RPM operation.
Original factory guide rails suffer from plastic aging, surface abrasion and crack formation after long-term contact with high-temperature engine oil and cyclic tension load. Worn rails lead to loud rattling noise on cold startup, timing chain deviation, disordered valve timing, and catastrophic piston-valve collision damage to the engine. This aftermarket replacement guide rail adopts upgraded reinforced composite material to deliver long-term reliable performance and steady repeat orders in global auto repair markets.
1. Cross Reference OEM Part Numbers
Mercedes-Benz OE: 276 052 01 00 / A2760520100
Interchange spare part number: 2760520000
2. Premium Material & Production Advantages
Glass Fiber Reinforced High-Temperature Composite Material
Main body made of modified PA66 plastic mixed with glass fiber and high-temperature lubricant additive. It resists long-term erosion of hot engine oil, features outstanding tensile strength and anti-cracking performance.
Integrated Precision Lubrication Grooves
One-piece molded oil channels evenly distribute engine oil across the contact surface with timing chain, reducing friction loss, slowing down surface wear and lowering running noise of the chain system.
1:1 OEM Contour & Mounting Dimension
Curved outline, fixing hole spacing and positioning slots fully match factory original standards. The rail fits flush against timing chain without gaps or offset after bolt-on installation.
Anti-Oxidation Anti-Aging Raw Material Formula
Special anti-aging additives blended into raw materials to slow hardening, embrittlement and permanent deformation under sustained high engine bay temperature.
Integral Injection Molding Process
Single-piece forming eliminates weak assembly seams, effectively avoiding breakage under alternating tension and vibration during engine operation.
