Engineered to suit the ARRMA KRATON 8S BLX Monster Truck, these GPM rear lower arms use Aluminum 6061 T6 to maintain high tensile strength while limiting added weight. The parts are intended as a durable upgrade to stock polymer arms for hobbyists seeking improved longevity.
Delrin collars are fitted at the pivot points to reduce friction and remove internal play, promoting consistent suspension movement. The hollow arm construction lowers mass without undermining structural integrity, and the multiple positioning holes allow precise changes to damper angle for setup refinement.
