These GPM rear lower trailing arms are produced from 6061 T6 aluminium to provide a stiffer, longer-lasting replacement for the stock components on the Team Losi Super Baja Rey 2.0. The thicker section improves resistance to deformation and enhances overall rear chassis stability. The hollowed profile reduces part mass while keeping a solid structural form, and the multi-hole layout supports fine tuning of damper angles for setup variation.
