The Yokomo D-156UM serves as a front upper mount specifically made for the DPR series upper A-arm and offers six distinct pivot positions to vary upper link geometry. It is intended for RC drift package configurations and fits the DP-DPRA and DP-DPRH chassis.
Adjusting the pivot point shifts the roll center and changes leverage on the upper link in measured steps, which influences initial steering and mid-turn behavior. When experimenting, alter one position at a time and log the effect on steering response and overall balance.
To install, remove the existing upper mount on the DPR upper A-arm and fit the D-156UM using the chassis original mounting points. Basic suspension linkage tools are enough; always confirm full arm movement and steering clearance after installation.
