The Tamiya 49309 TRF Damper Cylinder Cap in blue is a machined aluminium replacement for the factory upper cap, intended to increase durability and give a neat, consistent mounting point for the shock assembly. It suits drivers looking to tweak handling without altering internal shock parts.
By using aluminium at the damper top, the component reduces wear on the assembly and helps preserve precise geometry under load. The cap's exact tolerances promote repeatable shock performance and stable damping feedback across different surfaces.
Replacing the stock cap is a direct swap and requires minimal disassembly. Ensure threads are clean and hand-tighten initially, then secure to recommended torque to avoid over-stressing the shock body.
