With a lightened aluminum pulley you reduce the masses in the belt drive system of the M102 engine of your Mercedes 190E 1.8, 2.0, 2.3, 2.3-16 or 2.5-16 including evolution models and thus provide more power and improved response. A variant with a smaller diameter is also available for this purpose.
The pulleys are made in Germany from 7075 aluminum and then anodized black for protection.
A true OEM+ upgrade: production-like look, higher quality material and improved performance.
Tip: Save when buying the complete set of pulleys for crankshaft, water pump, power steering pump and alternator.
