Red Line | LightWeight 5WT Suspension Fluid - 16 oz

Red Line LightWeight 5WT Suspension Fluid is a synthetic suspension fluid designed as a more stable direct replacement for many OE 7WT suspension fluids. Red Line notes that it is commonly used by motorcycle technicians in non-revalved Showa and Kayaba front forks.

Its advanced formula provides superior shear stability compared to many popular shock oils, allows the use of lighter viscosities, significantly reduces shock fade, lowers operating temperatures at comparable viscosity, and helps eliminate most foaming while providing excellent seal lubrication. Anti-wear additives also help extend suspension component life.

This product is also commonly used in Sprint Car racing, as well as CORR and SCORE Off Road competition. Like other Red Line suspension fluids, it can be blended with other fluids in the range to create intermediate viscosities for more precise suspension tuning.
