The company AMR Suspensiones has developed a system of auxiliary and front integral suspensions for the FIAT 244 and 250 chassis, taking advantage of the original front shock absorbers of the vehicle, thus facilitating repairs (possible change of shock absorber).

These systems have been developed in response to the problems that arise over time in motorhomes, as the front springs lose their elongation. For control, it has developed a microprocessor system that controls both front and rear suspensions, being able to modify the program when there are new updates.

In AMR workshops, if the motorhome has the rear suspensions fitted, these can be integrated into the new system and controlled by the microprocessor system.
