Aluminum Front Lower Arm Upgrade for Tamiya DT-03 JR-DT300-LB by Jazrider  [JR-DT300-LB]

Front lower suspension arm upgrade for DT-03

This is an RC-scale front lower suspension arm intended for use with the Tamiya DT-03 chassis and listed as model JR-DT300-LB. The machined aluminium body delivers a precise mounting surface to help align front suspension links and wheel hubs on 1/10 on-road vehicles.

Fitment uses the DT-03 lower arm attachment points and the chassis' existing fasteners; confirm the arm's orientation and that ball joints sit square before tightening to final torque. As a metal upgrade the arm changes front stiffness relative to many plastic options, so expect some variation in steering behaviour when implementing tuning updates.

The piece is aimed at on-road tuners who require repeatable geometry adjustments and a durable alternative to stock parts. Always verify compatibility with your DT-03 variant and consult the product listing for details on included components.

Fit this aluminium lower arm when you want a metal solution for consistent front suspension geometry on DT-03 1/10 on-road cars; check clearances and mounting before use.
