Tamiya XV-01 Rear Lower Aluminum Arm - XV01-13405-LB by Jazrider  [XV01-13405-LB]

Machined rear lower arm for XV-01 applications

This aluminum rear lower suspension arm is produced to serve as a replacement for Tamiya XV-01 chassis assemblies and is marked XV01-13405-LB. It provides a metal option over the stock plastic part where geometry permits, aimed at drivers wanting more durable and consistent suspension behavior.

Installation guidance: use existing hinge pins and fasteners when they are dimensionally compatible, verify hub and pin interfaces before final tightening, and recheck wheel alignment after fitting. Allow for small clearance differences compared with plastic and make incremental setup changes to avoid surprises.

Tuning benefits: a stiffer rear lower arm helps maintain suspension geometry under load for clearer roll centre, anti-squat and rebound testing. Pair the arm with matching uprights and adjust damping and springs to characterise handling changes during setup sessions.
