Overview
The Racers Edge 80,000 cSt Pure Silicone Differential Fluid is a precision-formulated, 100% pure silicone oil engineered to deliver consistent, repeatable damping inside RC vehicle gear differentials. Sold in a generous 70 ml (2.36 oz) bottle with a fine-tip applicator, it gives racers and bashers the right viscosity to fine-tune on-power and off-power handling on any surface.
Pure silicone construction means the fluid resists thermal breakdown, maintains its viscosity across a wide temperature range, and will not foam, separate, or shear under load. The result is predictable diff action lap after lap, run after run.
Key Features
- 100% pure silicone differential fluid
- 80,000 cSt viscosity for precise diff tuning
- Generous 70 ml (2.36 oz) bottle
- Fine-tip applicator for clean, controlled fills
- Stable viscosity across temperature swings
- Resists foaming, shearing, and breakdown
- Compatible with most sealed gear differentials
- Works in front, center, and rear diffs
Performance Benefits
- Predictable on-power and off-power steering response
- Improved corner exit traction with the right viscosity
- Reduced diff outdrive wear from consistent damping
- Repeatable setup from race to race
Usage Notes
- Heavier viscosities (higher cSt) slow diff action for more traction and stability — ideal for high-grip surfaces, big jumps, and the center diff in 1/8 scale buggies and truggies.
- Lighter viscosities (lower cSt) free up the diff for more steering and rotation — useful on low-grip dirt or for the front diff to reduce push.
- Always fill diffs to the manufacturer's recommended level and rebuild seals if leakage is observed.
