High-quality Timing Chain Guide Rail 2760 5219 16 for Mercedes-Benz -

This premium timing chain guide rail carries OEM reference number 276 052 19 16, manufactured strictly by 1:1 original mold for Mercedes-Benz vehicles equipped with M276 3.0T / 3.5L V6 gasoline engines.
It is an essential wear-resistant component of the engine timing system, installed beside the timing chain to limit chain deflection, reduce chain vibration and noise, maintain stable chain tension, and prevent chain jump or disengagement during high-speed engine operation.
Original guide rails are prone to wear, cracking and plastic aging after long-term exposure to high engine oil temperature and cyclic tension. Damaged rails will lead to abnormal rattling noise at startup, timing chain deviation, valve timing disorder, and even severe engine collision damage. This aftermarket replacement rail adopts upgraded wear-resistant composite material to deliver long-lasting stable performance and consistent repeat orders in global auto repair markets.
1. Cross Reference OEM Part Numbers
Mercedes-Benz OE: 276 052 19 16 / A2760521916
Interchange spare part number: 2760521816
2. Premium Material & Production Advantages
Reinforced High-Wear Composite Material
Main body made of glass fiber reinforced PA66 composite plastic, mixed with high-temperature lubricant formula. It resists long-term erosion by high-temperature engine oil, with strong tensile strength and anti-cracking performance.
Integrated Smooth Lubrication Groove Design
Precision molded surface lubrication channels evenly distribute engine oil on the contact surface with timing chain, lowering friction coefficient, reducing wear and running noise of the chain.
Accurate OEM Contour & Mounting Position
Curved outline, mounting hole positions and fixing slot dimensions fully replicate factory specifications. It fits perfectly against the timing chain without gap or deviation after installation.
Anti-Aging & Heat-Resistant Formulation
Special anti-oxidation additive added to raw material, effectively delaying hardening, embrittlement and deformation under sustained high engine bay temperature.
One-Piece Injection Molding Craft
Integral forming process eliminates assembly gaps, avoids breakage under alternating tension load during engine operation.
