This lubricant is specially designed for speed way, rally, raid racing vehicle gearboxes such as all mechanical transmission, synchronized or not synchronized gearboxes, gearbox / differential, transfer gearboxes and hypoïd differentials without limited slip system operating under shocks, heavy loads and low revolution speed or moderate loads and high revolution speed. The 100 percent synthetic extreme pressure lubricant provides an efficient anti wear protection, a better resistance at high temperature and a longer life time. The 0 percentage shear loss results in a unshearable oil film in extreme conditions. IT stays in 90 grade after KRL 20 hours shear test as requested by SAE J306 Standard, July 1998 update. The very high lubricating power decreases friction and wear. IT stays at 90 grade at hot temperatures to provide outstanding oil film resistance at hot temperature and / or to reduce transmission noise. The fluid remains at low temperatures to allow easier gear shifting when the gearbox is cold thus less effort is required on the gear lever to shift the gears. It is suitable for any type of seal and yellow material used in gearboxes design and has anti-corrosion and anti-foam properties.
