The proven solution.

Auxiliary leaf springs – cost-efficient OEM solution for heavy body structures.

Overloaded motorhomes and transporters particularly benefit from additional leaf spring systems, which stabilise the rear, optimise suspension travel and significantly increase driving stability. Manufacturers already prefer to use our Leaf Springs during the production of motorhomes to reliably cushion the high permanent loads of a body structure. At the same time, the solution offers a clear cost-benefit advantage: It noticeably increases stability, load capacity and driving behaviour – without adding complexity to the production process. High-quality hardened steels, rolled spring ends and precisely defined spring characteristics ensure precise, controlled rear axle suspension. A sagging spring pack – typical of heavy body structures – can be restored with an additional spring leaf, the rear raised and the clearly defined suspension travel reinstated. In heavily loaded vehicles, our auxiliary leaf springs also enable a technically tested payload upgrade for the rear axle and the permissible gross vehicle weight, provided that alloy wheels and tyres are designed accordingly. Depending on the vehicle type, the front axle can also be optimised: Optimised Coil Springs are used here to further improve suspension travel and driving comfort. The result is noticeably harmonious handling, greater stability and a secure road position, even under consistently high loads. For customers seeking even greater flexibility, auxiliary or full air suspension systems also offer additional comfort, safety and adjustment options through a variably adjustable ride height and an extended range of performance. At our Goldschmitt Technik-Centers, experienced specialists provide comprehensive advice and find the optimum solution for every vehicle.

Auxiliary leaf springs are used as original equipment by many motorhome manufacturers to give heavily loaded transporter chassis more spring force and stability. They also provide the necessary load capacity in commercial applications – for example, in workshop or service vehicles with heavy equipment and shelving systems.

How leaf spring suspension has enabled driving comfort and stability for centuries.

Leaf spring suspension has a remarkable technical tradition that began long before the development of modern commercial vehicles. Even in the earliest coaches and carriages, layers of springs stacked on top of one another ensured that passengers travelled in greater comfort and vehicles were more resilient – a decisive advancement at a time when roads were often poorly developed. This technology also remained indispensable in the pioneering years of the automobile: classics such as the Ford Model T and the Citroën Traction Avant relied on robust leaf springs to ensure stability, load capacity and reliability. This long history demonstrates how proven and versatile leaf spring construction is – and why it continues to play a central role in transport vehicles today, particularly when it comes to high axle loads, structural robustness and continuous stress.
