The Tamiya 53938 Aluminium R Upright is a focused upgrade for model racers who want tighter handling on grippy road layouts. Intended for reversible suspension setups, the part repositions the bearing closer to the hinge pin versus comparable pieces like item 53807 to improve stability through bends.
Racers looking for cleaner entry and steadier mid-corner behaviour will notice the difference. The lowered bearing location enhances stability and responsiveness, helping drivers hold a tighter line during competitive runs.
This aluminium upright installs on multiple chassis types that use reversible suspension and is part of ITEM 49394 TRF415MSX Marc Rheinard Edition for seamless fitment. It is a good choice when dialing in a car for timed runs on smooth, high-traction surfaces.
