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

Durability-focused stabilizer for ZX7.5

The Kyosho LA422-13 stabilizer bar serves as a replacement element for the LAZER ZX7.5 range and explicitly notes SB and RB7.5 compatibility in its designation. As a scale RC part it is intended to affect roll characteristics and chassis balance, not for use on full-size vehicles.

By linking left and right suspension inputs the stabilizer reduces excessive roll and becomes an adjustable item for tuning understeer and oversteer tendencies on LAZER ZX7.5 models. The 1.3 specification denotes the cross-section size used by this bar within the product family.

Fitting the stabilizer follows the same basic steps as replacing the factory item: access the rear subframe mounts on the LAZER ZX7.5, remove the securing hardware, and swap the bar while keeping link orientations correct. After fitting, confirm that ball-end joints rotate freely and that the suspension moves without restriction.

For longevity, inspect attachment points after each session and look for any wear or loosening of fasteners. Small setup changes can noticeably shift roll stiffness, so document adjustments and monitor the condition of endlinks and mounting hardware to preserve consistent handling.

Use the LA422-13 as a durable, direct-replacement tuning component on compatible LAZER ZX7.5 SB and RB7.5 variants to control roll behaviour during setup and maintenance.
