SKF VKMA vs VKMC: What's the Difference?
When replacing a vehicle's timing belt system, one of the most common questions is the difference between SKF VKMA and SKF VKMC timing belt kits. While both kits are designed to restore reliable timing system performance, they serve slightly different maintenance needs.
The SKF VKMA Timing Belt Kit includes all the essential components required for a standard timing belt replacement. Depending on the vehicle application, a VKMA kit typically contains a timing belt, tensioner, idler pulley, and the necessary installation hardware.
The SKF VKMC Timing Belt Kit with Water Pump contains everything included in the VKMA kit, with the addition of an SKF engine water pump, the required gasket or O-ring, and any vehicle-specific mounting hardware. In simple terms:
VKMC = VKMA + Engine Water Pump
SKF strongly recommends choosing a VKMC kit whenever the water pump is driven by the timing belt. Since replacing the water pump usually requires the same labor as replacing the timing belt, installing both components at the same time helps reduce future repair costs, minimizes downtime, and improves long-term engine reliability.
For professional workshops and preventive maintenance, the SKF VKMC repair kit is often considered the most complete and cost-effective solution, ensuring that both the timing drive system and cooling system are renewed in a single service operation.
