This aluminium rear arm bulk is an aftermarket replacement designed to fit the TRAXXAS 1/18 Latrax Rally and is supplied as one 1pcs unit. The alloy construction provides a more robust substitute for the stock plastic part while preserving factory mounting points for direct fitment.
Installation procedure for experienced hobbyists: remove the original rear arm bulk, transfer linkage hardware and bearings as needed, orient the alloy unit correctly and secure with the original mounting screws. After installation confirm secure fastener engagement and full, unobstructed suspension articulation.
From a tuning perspective the aluminium bulk will affect rear suspension attachment stiffness and durability; factor this into any changes to shock setup or rear geometry. This component is sold as an aftermarket replacement intended for RC use only.
