Red Line HeavyWeight 30WT is the heaviest fluid in the suspension range. Red Line notes it is comparable to what other manufacturers label a 15W or 20W, so check the intended weight rather than the number on the bottle. Sold as a case of 12 16 oz bottles.

Key Features

  • Least viscosity change with temperature of any commercial suspension fluid, per Red Line
  • Superior resistance to cavitation for consistent damping
  • Very low foaming, with good seal lubricity and antiwear properties
  • Can be blended with other Red Line suspension fluids in any proportion to reach an intermediate weight
  • Used in many Harley-Davidson and American V-Twin motorcycle forks and rear shocks that have not been revalved
  • Comparable to what other manufacturers call a 15W or 20W
  • Superior shear stability over most popular shock oils
  • Far less shock fade, with lower operating temperatures for the same viscosity than conventional fluids

Applications

Motorcycle forks and rear shocks, racing shock absorbers, and other damper applications where the fluid weight is selected to suit the valving.
