The answer is not always straightforward \u2013 it depends on the type of vehicle, the operating conditions and the budget. This guide gives you all the data to decide correctly.<\/p>\n<h2>What does OEM mean in exchange?<\/h2>\n<p>OEM (Original Equipment Manufacturer) means that the part was manufactured by the same supplier that delivered the corresponding part to the manufacturing plant of the vehicle. For example, an MAN TGX truck leaves the factory with a clutch kit <a title=\"ZF Sachs truck clutches\" href=\"https:\/\/kothrosgreece.gr\/en\/factories\/zf-sachs\/\">ZF Sachs<\/a> or <a title=\"Schaeffler LUK clutch kit\" href=\"https:\/\/kothrosgreece.gr\/en\/factories\/schaeffler-luk\/\">Schaeffler LUK<\/a> \u2014 an OEM kit of the same company is therefore, literally, the same accessory as your vehicle originally had.<\/p>\n<p>The difference with the manufacturer\u2019s \u2018original\u2019 spare parts (e.g. original MAN or Mercedes) is mainly on the packaging and price \u2013 the content is often made by the same OEM provider, simply packed with the vehicle manufacturer\u2019s logo.<\/p>\n<h2>What is Aftermarket Replacement?<\/h2>\n<p>Aftermarket is any part that is not from the original OEM of a manufacturer.

Aftermarket is in quality \u2013 there are reliable premium options, but also low quality products of unknown origin.<\/p>\n<\/div>\n<\/div>\n<div>\n<h3>Do I have to pay more for a genuine clutch kit?<\/h3>\n<div>\n<p>For a professional lorry working intensively, yes \u2013 absolutely. The OEM kit can withstand up to twice as many kilometres from a medium aftermarket, reducing total maintenance costs (TCO) while avoiding emergency stops.<\/p>\n<\/div>\n<\/div>\n<div>\n<h3>Where can I find a genuine ZF Sachs or LUK clutch kit in Greece?<\/h3>\n<div>\n<p>Plastotechnics in Thessaloniki is an authorised distributor of ZF Sachs, Schaeffler LUK, Mahle and Miba. It has immediate availability on mission throughout Greece on the same day.<\/p>\n<\/div>\n<\/div>\n<div>\n<h3>How do I recognise a fake or low-quality aftermarket kit?<\/h3>\n<div>\n<p>Low quality marks: absence of hologram or QR certification code, absence of technical documentation, abnormally low price, unclear or unreadable printing on the packaging. Always buy from authorised distributors with a traceable product code.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<h2>The True Choice for Your Pole<\/h2>\n<p>If you run a professional truck or fleet, investing in a genuine OEM truck clutch yields \u2013 with fewer interruptions, lower overall costs and greater reliability.
