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

Rear stabilizer: fit and swap guide

This Kyosho LA422-13 stabilizer bar is a replacement part made for the LAZER ZX7.5 family and shows the compatibility markers SB and RB7.5 as indicated in the original listing. It is an RC component intended to influence roll response and chassis balance rather than any full-size application.

The stabilizer links left and right suspension movement to reduce unwanted body roll; use it as a tuning item to move the understeer/oversteer balance and refine cornering behaviour on LAZER ZX7.5 machines. The 1.3 specification in the name refers to the section sizing for this part line.

Installation is straightforward when changing the factory unit: find the rear subframe mounting points on the LAZER ZX7.5, remove the retaining hardware, and install the LA422-13 while keeping the endlinks oriented correctly. Verify free movement at the link ball joints and make sure the bar does not bind through the full suspension travel.

When tuning, make small, measured swaps: changing to this stabilizer alters roll stiffness compared with the original part, so test with consistent suspension and tyre choices, note handling differences, and adjust other setup items like sway rates or shock damping as needed. Regular inspections after running sessions will reveal wear at attachment points and keep handling predictable.

Fit the LA422-13 as a direct-replacement option on compatible LAZER ZX7.5 SB and RB7.5 variants to fine-tune roll behaviour during setup sessions.
