Front Chassis Stiffener for LAZER ZX7.5 - Kyosho LA413  [KY-LA413]

Overview of the LAZER ZX7.5 front stiffener

The Kyosho LA413 Front Stiffener is a purpose-built front-end reinforcement for the LAZER ZX7.5 model. It acts as a tuning accessory to adjust chassis flex characteristics without altering suspension geometry.

In use, the stiffener increases front rigidity and thereby influences steering feel, mid-corner behaviour and transient responses. Competitors install it to reduce nose flex, gain consistent handling across runs, and fine-tune understeer or oversteer according to track conditions.

Installation is straightforward for anyone familiar with RC maintenance: the stiffener mounts to factory front bulkhead points using the model's fasteners. Verify hole alignment and screw length before final assembly, check for steering linkage and servo clearance after fitting, and apply threadlocker to metal fasteners when needed. Observe the correct torque for small RC screws.

Because this part is produced to fit the LAZER ZX7.5, confirm compatibility with your ZX7.5 variant before ordering. It is intended solely for tuning and setup work.

Employ the LA413 to target front stiffness improvements while keeping other setup parameters stable so you can measure its handling impact accurately.
