The Tamiya 53995 TRF501X Reinforced Upper Arm Mount is a practical part for pilots wanting firmer upper arm support on their TRF501X. It adds reinforcement to the suspension mount zone to reduce flex under load and keep your setup predictable.
Built from robust materials, this mount helps the suspension keep its geometry during high corner loads. That translates to steadier steering input and more reliable feedback through fast sections.
Specifically shaped for TRF501X assemblies, the mount installs without major alteration to the chassis layout. It is suitable for tuners who want a straightforward parts swap to increase chassis toughness.
