OPTITEMP RACING CBT is a fully synthetic grease designed for extreme loads in all types of constant velocity joints. Due to its special ceramic additives it ensures extremely low coefficients of friction and applications at extreme temperatures. The product further reduces the temperature in the joint and improves the noise and vibration behavior (NVH). The compatibility with conventional boot materials is excellent.Application at extreme temperatures: - 40°C low temperature, 160°C permanent temperature (in CV joints), 200°C short-term peak temperature (in CV joints)
