The DJ High Performance Torque Lubricant has been created specifically for RCM, to be used in conjunction with our extensive range of performance engine components. With its unique blend of anti-wear chemicals and high graphite content, the RCM assembly lubricant significantly aids in the stabilization of tension loads during torque proceedures. 1 x 15gm sachet of RCM lubricant is included with all of our Head Stud Kits as standard.
