TRF Works Damper Set
This upgraded version set replaces the damper cylinders, piston rods, O-rings, and medium springs of Item 42102 with higher-grade HL (High Lubrication) cylinders, TRF piston rods, X-rings (50 Durometer), and soft springs respectively. Aluminum spring retainers have been added as well.
One thing I would mention is that a friend of mine got the version for the M-Chassis. And the Cylinder nut is different, the m-chassis version did not have the 12mm O-ring insert ones. Not sure why that is…
