Upgrade your ARRMA KRATON 8S BLX with the GPM MAKX181F/RSN dog bone and differential outdrive set to increase toughness on uneven terrain. The pieces are made from 4140 medium carbon steel with the dog bone diameter increased from 5.5mm to 7mm to resist bending and chipping. A thicker 5mm needle improves durability and helps the joint run more smoothly between the CVD shaft head and cup.
