ATTENTION
Before you can continue, you must agree to all of the following terms:
The RM Series is comprised of a damper cartridge secured within a threaded outer body. This specific design requires a lubricating grease to be applied during the assembly process between the two damper and threaded body to avoid metal-to-metal contact. In order to keep the two components from touching each other and generating noise transmission you will need to periodically clean out the old grease and apply new grease.
This is a simple process that can be done with just a few common tools. It does not require you to open the internals of the dampers themselves and therefore you do not need to have the dampers re-pressurized after carrying out this procedure. Please contact us on info@mlperformance.co.uk for more information and a step-by-step guide on how to complete this maintenance.
As a result of this required maintenance, we do not recommend the RM Series for road use over the BR Series or ER Series.
