Technical Overview

The AWD-14 damper spring is an aftermarket tuning component intended for Kyosho Mini-Z AWD shock assemblies, including MR-03 AWD configurations. It provides a direct-fit replacement for the stock spring and allows fine adjustment of vertical stiffness without modifying shock bodies or piston geometry.

Installation requires basic Mini-Z service skills: remove the wheel and shock assembly, decompress the shock to access and replace the spring, then reassemble. Use precision hand tools and verify even spring seating to avoid asymmetric preload or binding during full travel.

From a setup perspective the spring adjusts initial bite, mid-stroke support and ride height. Use measured, incremental changes and record results on a controlled surface to map the AWD-14 effect on handling balance and transient response.

What clearance checks are recommended after fitting?

Verify full suspension travel with the vehicle supported and wheels free, check for spring shift on the perch, and ensure no contact between spring coils and adjacent components.

Is spring matching required across the axle?

For consistent handling it is advisable to match spring rates on each axle; mixed rates can be used intentionally for tuning but expect noticeable changes in balance and turn-in.

Any maintenance notes for long-term use?

Inspect springs periodically for wear, corrosion or loss of free length, and confirm seating and retainer integrity during routine suspension checks.
