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

Tune roll balance with the 1.3 stabilizer

The Kyosho LA422-13 stabilizer bar is supplied as a spare for the LAZER ZX7.5 line and includes the compatibility tags SB and RB7.5 as shown in the original designation. It is an RC-specific part designed to change roll response and chassis balance for better cornering feel.

Functionally the stabilizer ties the left and right suspension to limit excessive roll; drivers use it as a tuning lever to modify understeer versus oversteer balance and to alter turn-in and mid-corner characteristics on LAZER ZX7.5 platforms. The 1.3 label refers to the cross-section dimension used in this bar series.

To install, access the rear subframe mounting points on the LAZER ZX7.5, remove the existing fasteners and swap in the LA422-13 while noting endlink alignment and orientation. Confirm free movement at the link ball joints and ensure no binding throughout suspension travel.

When testing changes, make incremental swaps and log handling differences: changing to this stabilizer will affect roll stiffness relative to the stock item, so keep suspension and tyre choices consistent while adjusting sway rate, shock damping, or other setup items to dial in the desired behaviour.

Select the LA422-13 as a tuning upgrade for compatible LAZER ZX7.5 SB and RB7.5 variants to refine roll control and on-track balance.
