Made in the USA
Built for racers who tune by feel
Franchize Racing makes silicone shock and diff fluids for people who win by margins — where a single weight change is the difference between a car that rotates and one that pushes.
Consistency is the whole point
Every batch is blended in the USA to tight tolerances and checked before it goes out. That matters more than any single spec: when you change from 400 to 450, you should feel the change you intended — not batch variance pretending to be a setup change.
Our fluids are rated in true centistokes. Weight numbers printed on other brands are not standardized, which is why we publish a full cross-reference chart instead of asking you to guess.
What goes in the bottle
- Pure silicone — no fillers, no thickeners cutting the blend
- Anti-foam formulation — resists cavitation through long runs
- Temperature stable — holds rated viscosity from a cold pit lane to a hot main
- Shear stable — diff fluids resist breakdown under load
5108 Speed Works
Franchize Racing is a 5108 Speed Works brand. Our fluids are blended to 5108 Speed Works spec — the same standard we run on our own cars.
