Service assemblies are used in trucks, tractors and trailers to minimize adverse effects like bumps and loss of vehicle balance due to road conditions, and to ensure road safety through a balanced load.

The service assemblies produced and sold under Meklas brands are mainly sold as spare parts in refurbishment market; for their warranty conditions to be valid, they should replace a Meklas brand product or be mounted through mounting parts supplied by Meklas approved suppliers.
