Efficiency is further increased by utilizing titanium-coated shock shafts for smoother travel, while damper cap, O-ring cap, and spring retainer have been anodized Tamiya blue to provide vivid chassis highlights. This shock set includes white-colored medium rate springs, and all the parts needed to build four complete shocks. Does not include shock oil.
