30/8T Reverse HD Steel Triangular Keyed Bevel Helical Cut Diff Gear w/ Spool Set for BRX70/BRX80/BRX90 PHAT™ Axle

This heavy-duty steel reversed-cut helical triangular-keyed gear set is designed for the rear axle of the BRX01, BRX02, and BRX01 AWB. It uses an AR44-style ring and pinion with matching locker, but features a flipped differential design for counter-rotating drivetrains.

The set includes a hardened steel 30T/8T helical bevel ring and pinion, input shaft, and differential locker (spool), delivering exceptional strength, durability, and smooth power transfer.

Engineered for use with opposite-spinning center driveshafts, this gear set enables a counter-rotating drivetrain to effectively reduce torque twist and improve overall chassis stability.

Features:

Hardened steel gears for maximum strength and durability, increased weight in the axle
Keyed spool to increase structural strength and to eliminate the weakness of the three M2.5 screws
Tight tolerance of the diff locker and the axle shaft
Tight tolerance of the bevel gear and input shaft to increase efficiency in the drivetrain

1x Reverse Cut Triangular Keyed HD Steel Bevel Gear 30T
