The GPM LMT21449 upper and lower link bar set is engineered for the LOSI 1/8 LMT 2.0 Grave Digger to enhance chassis stiffness and reduce suspension deflection under load. Fabricated from 7075-T6 aluminium, these link bars offer a high strength to weight ratio and maintain suspension geometry during demanding driving. The arcuated seating around the steel pivot ball secures the ball position and limits unwanted movement, supporting consistent suspension kinematics.
