Rail dampers play a crucial role in maintaining the safety and efficiency of rail systems. Their typical replacement every 1 to 1.5 million kilometers (every 6-10 years) as part of the bogie overhaul is not just a matter of routine; it is an important practice that ensures the safety, performance and sustainability of a rail fleet.

With ZF Aftermarket damper retrofitting, we offer you ZF quality dampers for installation to your fleet – giving you more flexibility and choice when it comes to damper replacement.

Upgrade your fleet

What is damper retrofitting?

Damper retrofitting is the process of replacing the original vehicle OEM installed damper with a new damper from an alternative manufacturer that meets the quality standards of the original. This makes you less dependent on the manufacturer of the originally installed damper and can increase the safety and performance of your vehicles.

Did you know? The best time to retrofit a damper is within the first two overhaul intervals therefore maximising the lifecycle benefit for the fleet. So don't miss your opportunity to extend your vehicle's life span and upgrade your fleets with ZF Aftermarket dampers.

The industry standard permits a deviation of no more than 10% for the retrofitted damper compared to the original brand (damping forces). With our know-how and technical expertise, we ensure optimum damper performance.

How it works

Damper retrofitting in 3 easy steps

icon step 1
We receive the specifications

You provide us with a drawing or the neutral vehicle specification for the damper to be replaced.

Don’t have the drawings to hand? No problem! You can also send us a physical sample and we gather all necessary specification.

step 2 icon
We design

After receiving the specifications, our experts will take over and design your retrofittable damper from our modular construction kit. On this basis, we will provide you with a proposal for the requested dampers.

icon step 3
We deliver

Once you have approved the design proposal, we will immediately produce your retrofitted dampers – ready to be installed.

Good to know: Our retrofit dampers have the same performance and longevity as running ZF models – and are therefore available for further overhaul cycles to come. This means that ZF retrofitted dampers can boost your supply chain resilience.
