TRF421X Upper Arm Nut Set Blue RC Spare Part

The TRF421X Upper Arm Nut set in blue is a focused RC spare part for suspension maintenance where the exact fastening point matters. With 4 matching nuts in one pack, it supports clean replacement work on the upper arm position named in the designation and keeps the hardware consistent across the assembly. The blue colour gives the set a clear visual distinction during bench work, making the nuts easier to separate from other small fasteners in a parts tray or toolbox. That matters most during rebuilds, routine servicing or when a missing fixing needs a like-for-like replacement instead of a generic alternative. Because the data identifies these specifically as TRF421X upper arm nuts, the set is suited to precise parts management within that model platform rather than general mixed hardware use. This kind of small component often becomes important during suspension work, where secure fastening and correct placement keep the assembly process moving without interruption. Kept as workshop stock or added to a race-day spares case, the 4-piece set covers the named nut type in a compact format that is easy to store and quick to reach when maintenance is underway.
