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

Rear gear box for B-MAX4 III

This is an RC-scale rear gear box assembly intended for the Yokomo B-MAX4 III chassis, supplied with a stabilizer holder as indicated in the product name. The component serves as a direct replacement or service part for the rear drivetrain, keeping the B-MAX4 III rear-end layout intact without altering core chassis geometry.

Installation and fitment: the unit installs into the rear section of the chassis where the original rear gear box resides and pairs with existing drivetrain components on a stock B-MAX4 III. Follow your standard teardown sequence for rear-end service, check mesh and axial alignment during reassembly, and verify stabilizer mounting points align with your chassis stabilizer system.

Tuning role: the included stabilizer holder provides the mounting location for a rear stabilizer bar, allowing adjustments to roll stiffness and rear-end balance without modifying the main differential or spur/pinion setup. Use this part when you need to replace a worn gearbox or restore correct stabilizer geometry during setup changes.
