The Tamiya 95392 JR Reinforced Gear Cover is a purpose-made upgrade for Mini 4WD cars using the MS chassis. Produced in a reinforced blue plastic, it improves the stiffness around the gearbox to assist with handling consistency during competitive runs.
The added structural support reduces gearbox area flex, which can help the car hold its line through fast corners and transitions. It works well with typical MS chassis tuning parts, allowing modelers to balance stability and agility.
Installation is straightforward and includes the small fixing parts needed to attach the cover. The cover locates cleanly on the MS chassis and usually requires only simple hand tools to fit.
