The Tamiya 54042 piston rods feature a hard titanium coating to resist wear and lower sliding friction inside TRF501X shocks. They are aimed at users who want longer service intervals and steadier damper action.
Titanium coating helps prevent dust and small particles from abrading the rod surface, so seals remain effective and movement stays fluid. This is handy for regular off-road use where dirt ingress is common.
These rods are compatible with standard TRF501X shock assemblies and provide a straightforward upgrade path for improved suspension durability. Routine checks will keep them performing reliably.
