Yokomo Y2-501MRA Lightweight Diff Joint Set for YD-2  [Y2-501MRA]

Cut weight and sharpen YD-2 response with Yokomo Y2-501MRA

Fit the Yokomo Y2-501MRA Aluminum Ball Differential Joint Set to your YD-2 to shed unsprung weight while keeping structural strength. These aluminium joints are intended to replace stock gear differentials and deliver crisper steering input and quicker transient response for racers focused on lap time and consistency.

Benefits of aluminum diff joints for racing

Aluminium offers a favourable strength to weight ratio that racers prize for tight handling. Swapping to aluminium diff joints lowers inertia at the drivetrain and helps the car change direction faster, all without sacrificing durability for regular track use.

Fitment notes and required parts

Upgrading from a standard gear differential or a steel ball diff joint requires a drive cup protector (B8-500DP?360) to secure the dogbone end of the universal shaft. The Yokomo Y2-501MRA set ships with matched left and right joints so you get a full replacement for both sides.
