Engineered for Team Losi SUPER BAJA applications, this front upper arm pair provides a rigid mounting point for the knuckle and reduces pivot play. Supplied as one pair (2 pcs), the arms are CNC-machined from 6061 T6 aluminium to replace compliant plastic or stamped metal arms where improved stiffness and repeatable geometry are required for competitive setups.
Pressed Delrin collars in the pivot bore reduce radial clearance and ensure repeatable pivot alignment. Stainless steel ball elements, rings and screws are specified to resist corrosion and maintain durable bearing surfaces under repeated loading. The arm profile preserves original suspension kinematics while increasing torsional stiffness to limit deflection under lateral loads.
Installation mirrors standard suspension arm replacement procedures: remove factory arms, transfer any required bushings or hardware, and install the replacement arms using the stock hinge pin and knuckle locations. The CNC tolerances and anodised finish support consistent part interchangeability when correctly mounted.
For hobbyists seeking a precision, stiffer front end and consistent steering behaviour on Super Baja chassis, these CNC 6061 T6 arms provide robust serviceable upgrade performance and dimensional reliability.
