Specifically matched to the ARRMA KRATON 8S BLX Monster Truck, these GPM rear lower arms use Aluminum 6061 T6 for a balance of strength and lightness, making them suitable for hard use and regular trail or park runs.
Each arm uses Delrin collars to limit friction and remove unwanted gap, resulting in cleaner pivot action. The hollow construction reduces rotating mass while retaining structural support, and the multiple mounting holes give simple damper angle adjustment for personalised setup changes.
