These GPM spring steel rear shock springs are intended as a robust replacement for the Team Losi Super Baja rear shock assembly. Key dimensions are 109mm overall length, 29mm outer diameter and 24mm inner diameter. Coil thickness is 2.5mm, 0.2mm thicker than the original item, delivering increased fatigue resistance and firmer compression control under repeated impacts. The springs are finished in bright black for corrosion resistance and visual consistency with standard hardware.
