Red Line LightWeight 5WT is comparable to what most manufacturers call a 5W, and it is a common upgrade for factory 7wt fork oil that shears down in service. 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
- Popular as a direct, more stable replacement for most 7WT OE suspension fluids
- Used by motorcycle technicians as a stable replacement in Showa and Kayaba front forks that have not been revalved, and in the rear shock on modern motocross bikes
- Often used by CORR and SCORE off-road teams in long-travel shocks for its ability to hold viscosity under extreme conditions
- Also used in Sprint Car racing
- Used by NHRA Top Fuel and Funny Car teams in clutch management systems as a substitute for water soluble fluid, for consistent operation hot or cold
Applications
Motorcycle forks and rear shocks, racing shock absorbers, and other damper applications where the fluid weight is selected to suit the valving.
