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

Compatibility notes for LAZER ZX7.5 variants

The Kyosho LA422-13 stabilizer bar is presented as a spare for the LAZER ZX7.5 family and retains the compatibility identifiers SB and RB7.5 from the original product label. It is intended as an RC-scale tuning item to influence roll response and chassis balance, not for full-size use.

Mechanically, the stabilizer reduces lateral body roll by coupling left and right suspension movement; it is an adjustable part used to shift the balance between understeer and oversteer and to refine cornering feel on LAZER ZX7.5 cars. The 1.3 reference in the name denotes the bar section size for this product group.

Standard installation involves removing the original rear stabilizer from the LAZER ZX7.5 rear subframe mounts, noting endlink orientation, and fitting the LA422-13 in the same position. After mounting, ensure the ball links move freely and that the suspension completes its travel without interference from the bar.

For setup work, expect measurable changes to roll stiffness when swapping stabilizers; test with consistent tyres and suspension settings, take notes on handling differences, and adjust related parameters such as sway rate or damper settings to achieve the desired balance. Regular checks will catch any wear at fastenings early and keep handling consistent.

Install the LA422-13 as a direct-fit tuning option on compatible LAZER ZX7.5 SB and RB7.5 models to refine roll characteristics during setup and maintenance.
