Kyosho LA422-16 Stabilizer Bar rear sway bar for SB ZX7.5 RB7.5  [KY-LA422-16]

Rear stabilizer bar overview

This LA422-16 rear stabilizer bar from Kyosho is a direct-fit RC accessory intended for use on SB, ZX7.5, and RB7.5 platforms where the part number is referenced. It functions as a rear sway bar to reduce chassis roll and refine balance during cornering, described here in RC-specific terms for fitting and setup.

Fitment is intended to the existing rear stabilizer mounts on compatible chassis, using the vehicle's stock attachment points and hardware. Installation is typically a straightforward swap of the rear bar, retaining original end links; verify alignment and free movement of the bar through suspension travel before running.

In tuning terms the LA422-16 adjusts roll stiffness: increasing rear bar stiffness reduces body roll and can shift balance toward understeer, while a softer bar increases rear compliance and can make the car more neutral or oversteer-prone depending on front setup. Use incremental changes and test laps to evaluate effects, and combine with shock and anti-roll settings for holistic balance.
