Heavyweight Synthetic 30WT Suspension Fluid has superior shear stability, less shock fade, low operating temps, seal lubricity, less foaming, & antiwear additives. It also blends with Red Line suspension fluids for intermediate viscosities.
Full Synthetic Heavyweight 30WT Suspension Fluid is used in many Harley-Davidson and American V-Twin motorcycle forks and rear shocks that have not been revalved. It is the ultimate in power and performance because of antiwear additives that assist in longer shock life, superior shear stability, far less shock fade, lower operating temps, seal lubricity, and anti-foaming properties. Shock valving on heavy motorcycles needs more viscosity. Red Line Suspension Fluid products can be mixed together to create intermediate viscosities, customized for a dampener's particular characteristics.
  • Better shear stability
  • Use of lower viscosities
  • Less shock fade
  • Lower operating temps
  • Eliminates foaming
  • Great seal lubricity
  • May blend to create intermediate viscosities
  • Least viscosity change of any suspension fluid on the market
