These GPM rear lower suspension arms for the Traxxas Slash Pro 2WD are crafted from 6061-T6 aluminium to provide a durable upgrade that supports consistent shock geometry. The design focuses on strength and reliable mounting across the multiple shock position holes, allowing for controlled adjustments to shock angle and rear-end behaviour. Installation is direct to the rear knuckle arms with no washers required, resulting in a tight, repeatable fit. The arms are compatible with original rear knuckle arms and with GPM Racing #SLA2W022, and are not compatible with GPM Racing #SLA022 or SSLA1277RH22.
