The JR-LB08-GU kit upgrades the stock servo saver and tie rods on the Tamiya CW-01 (Lunch Box) chassis with aluminium parts designed to improve steering stability and repeatability.
It includes a 25T spline hi-torque aluminium servo saver and matched aluminium tie rods to provide a stiffer connection between the servo and steering knuckles. This reduces deflection under load and helps maintain consistent steering geometry during repeated runs.
Fitting is expected for model builders familiar with the Lunch Box layout: remove the original saver and tie rods, fit the aluminium saver to the servo spline, then attach the tie rods to the steering arms using the existing ball studs or linkage. Always check spline seating and steering travel for binding after installation.
Notes on use: aluminium tie rods give stable toe and trim control while the metal saver preserves servo feedback with greater torsional resistance than many stock plastic parts. The JR-LB08-GU is aimed at hobbyists seeking a dependable steering interface for everyday use or club competition.
