Overview This set of 4 high-grade TRF front/rear racing dampers have damper cylinders that feature a newly developed black-colored fluorine coating for even less friction than previous damper cylinder coatings. Efficiency is further increased by utilizing titanium-coated piston rods for smoother travel, while damper cap, O-ring cap, and spring retainer are all in striking Tamiya blue to provide vivid chassis highlights. Includes white-colored medium suspension springs. *Compatible Chassis: Most on-road touring car chassis (TT-01, TA05, TB-02, TB-Evo.V, TRF415, etc.)
