#RDRP0747 - Revolution Design B84 Lightweight Ring Gear Set (For Modified and Stock)

Reducing rotating mass is the ultimate secret to a more agile and faster buggy. With the Revolution Design Lightweight Ring Gear Set for the Team Associated B84, you can take your drivetrain efficiency to the next level - perfect for both highly competitive Stock racing and high-powered Modified classes.

Innovative 2-Piece Design for Massive Weight Savings

The original factory part features a heavy, one-piece steel gear design that weighs in at 13.4g. Revolution Design (RDRP) completely re-engineered this component by utilizing a smart 2-piece construction. The RDRP set features a hard-anodized aluminum differential cover paired with a separate steel ring gear.

The result is stunning: The RDRP tuning part weighs an incredibly light 7.3g. This significantly reduces the rotational mass at a critical point in the drivetrain. Since the B84 uses two differentials, this upgrade provides a total weight reduction of 12g per car!

Track Performance Benefits:

• Faster Spool-Up: Less rotating mass allows your engine/motor to reach top RPM much quicker, resulting in explosive acceleration.

• Increased Drivetrain Efficiency: Less wasted energy means more power to the ground, which is crucial for maximizing top speed in Spec/Stock classes.

• Durable Construction: The combination of a hard-anodized aluminum cover and a tough steel gear ensures race-ready durability without the weight penalty.
