Yokomo YOKB4-302R Rear Gear Box for B-MAX4 III with Stabilizer Holder  [YOKB4-302R]

B-MAX4 III rear diff housing summary

This is a rear gear box assembly intended for the Yokomo B-MAX4 III chassis, supplied with a stabilizer holder as identified in the product name. The item functions as a direct replacement or service part for the rear drivetrain while preserving the B-MAX4 III rear-end layout and geometry.

Installation and fitment: the gearbox installs into the rear section of the chassis in place of the original unit and interfaces with the existing drivetrain components on a standard B-MAX4 III. Use your regular rear-end disassembly procedure, verify correct gear mesh and axial alignment during reassembly, and ensure the stabilizer attachment positions match your chassis stabilizer setup.

Tuning role: the included stabilizer holder provides the mounting position for a rear stabilizer bar, allowing you to alter roll stiffness and rear-end balance without adjusting the main differential or spur/pinion. Replace this unit to recover worn components or to restore accurate stabilizer geometry following setup changes.
