The XRAY XB8 Pivot Ball Steering Block is a tuning option for the XB8 2019 series buggies. XRAY's specially-formulated graphite composite material is recommended for medium to very-high traction tracks, as well as dusty conditions to ensure maximum possible free movement of suspension parts even if a lot of dust builds up around the pivot points. The exclusive composite mixture gives a perfect balance between reliability and performance; graphite parts provide a responsive feel without sacrificing durability.
