Tamiya DT-03 Aluminium Rear Lower Arm JR-DT301-LB by Jazrider  [JR-DT301-LB]

Rear lower suspension arm, DT-03 compatible

This aluminium rear lower suspension arm is designed for the Tamiya DT-03 chassis and carries model number JR-DT301-LB. It replaces the stock part to give a stiffer, more durable lower link without altering the baseline suspension geometry.

Key design points focus on material performance and fit: aluminium construction lowers the chance of deformation under stress versus factory plastic arms, and the arm uses the existing DT-03 mounting pattern. It suits drivers who want longer service intervals and consistent handling in varied running conditions.

Fitting is intended to be simple: remove the original lower arm, inspect and reuse compatible mounting hardware, then fit the JR-DT301-LB. Check pivots for free movement, secure retainers, and verify wheel alignment once installation is complete.

Use this arm when durability and dimensional stability are needed for DT-03 upkeep or incremental performance updates; always recheck alignment after fitting.
