The Kyosho UM576B bumper set gives the Ultima SB Dirt Master a tougher front end to handle knocks and bangs on uneven terrain. Built to mate with the Ultima SB chassis, the parts help keep vulnerable components safer during aggressive driving.
Trail riders and club racers who push their Ultima SB on bumpy tracks will benefit from this upgrade, seeing fewer front-end failures and quicker turnarounds between sessions.
