After multiple wins there, it has been proven equally superior in many other forms of racing, including NASCAR and off-road. It will provide superior dampening, control heat and lower operating temperatures, and eliminate shock fade. Lucas S1/S2 racing suspension fluid’s synthetic formula also contains special anti-wear and lubricity agents that produce excellent thermal stability. Size: 1 Quart.
