The Tamiya 49311 TRF Damper Aluminum Retainer in blue is a tidy upgrade for modellers aiming for tougher components and neater suspension behaviour. Replacing the factory plastic spring retainer, this aluminium part reduces flex and secures the damper spring more reliably. Its precise fit keeps the shock assembly aligned during hard runs.
Compared with plastic, aluminium stands up better to repeated loads and contact. Choosing this blue retainer helps preserve suspension geometry under stress and provides a consistent pivot for the spring. The anodised coating also delivers a smart, corrosion-resistant surface.
Designed with TRF compatibility in mind, the retainer drops into existing shock assemblies and is straightforward to install. Serious tuners and club racers will appreciate the more secure mounting and reduced chance of in-race part movement.
