PRODUCT DESCRIPTION

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

Includes:
  • 1x Reverse Cut Triangular Keyed HD Steel Bevel Gear 30T
  • 1x Reverse Cut HD Steel Input Shaft 8T
  • 1x Keyed HD Steel Differential Locker (Spool)
  • 3x M2.5 hardware

Will fit:
  • Boom Racing BRX70/BRX80/BRX90 PHAT Axle (Note: must be black color Third Member which fits reverse axle gear, red color Third Member will not fit)
  • AR44 style ring/pinion gear and locker with flipped diff feature
