Kyosho LA422-13 - Stabilizer Bar (?1.3)(SB/ZX7.5/RB7.5)  [KY-LA422-13]

Stabilizer bar for LAZER ZX7.5 series

This Kyosho LA422-13 stabilizer bar is a spare part intended for the LAZER ZX7.5 family, carrying the compatibility markers SB and RB7.5 noted in the original designation. As an RC-scale component it targets roll behaviour and chassis balance rather than any full-size application.

Functionally, the stabilizer bar reduces unwanted body roll by linking left and right suspension responses; it is used as a tuning element to alter understeer/oversteer balance and cornering feel on the LAZER ZX7.5 platform. The product carries a 1.3 specification reference in its name which denotes the designed section size used by this part line.

Installation is straightforward when replacing the factory stabilizer: locate the original mounting points on the rear subframe of the LAZER ZX7.5, remove the retaining hardware, and swap the bar while observing orientation and endlink alignment. Check for free movement at the link ball ends and ensure no binding occurs through suspension travel.

For tuning, small incremental changes matter: swapping to this stabilizer will change roll stiffness relative to the original part, so test on-track with consistent suspension and tyre settings, record lap feel, and adjust other parameters such as sway rate or shock damping accordingly. Regular inspection after running sessions helps detect wear at attachment points and preserves predictable handling.

Use this LA422-13 stabilizer as a direct-replacement tuning option on compatible LAZER ZX7.5 SB and RB7.5 variants to refine roll characteristics during setup sessions.
