The JR-LB08-GU replaces the standard servo saver and tie rods on the Tamiya CW-01 (Lunch Box) chassis with machined aluminium components intended for precise setup and tuning work.
Featuring a 25T spline hi-torque servo saver and matching aluminium tie rods, the assembly tightens the mechanical connection from servo to steering knuckles, reducing flex under load and helping maintain consistent steering geometry during aggressive driving.
Installation is direct for those experienced with the Lunch Box layout: remove the factory saver and tie rods, mount the aluminium saver onto the servo spline, then connect the tie rods to the steering arms using existing ball studs or linkage hardware. Confirm spline seating and check steering endpoints to prevent binding after fitment.
Tuning guidance: aluminium tie rods stabilise toe and trim settings and the metal saver sustains sharper servo feedback while resisting wear better than many original plastic parts. This upgrade is intended for RC hobbyists who want a firmer steering interface for tuning sessions and club events.
