Silicone 50000CPS SPECIAL DIFFERENTIALS

Total control of the differential with the appropriate viscosity

The Silicone 50000CPS Special Differentials (ref. MP012-50000) is a high-viscosity lubricant specifically designed for adjusting differentials in competition slot cars. Choosing the right silicone is one of the most important preparation decisions a driver can make: the viscosity of the fluid that fills the differential largely determines how the car responds in corners, how torque is distributed between the wheels, and how much traction is offered on exit.

Main features

• Viscosity 50000CPS: high grade within the range of silicones for differentials. Higher viscosity means greater resistance to relative rotation between the two wheels of the axle, resulting in behaviour closer to that of a locked differential.
• Specific formulation for slot differentials: compatible with the common materials of these assemblies (plastic, metal, seals).
• No corrosive effects on the internal components of the differential.
• Stability over time: maintains its viscosity properties without degrading quickly due to the friction heat generated during operation.

Function and performance on track

The differential in a slot car serves to allow the two rear axle wheels to rotate at different speeds when the car takes a corner. However, the amount of "freedom" that differential has directly depends on the viscosity of the fluid with which it is filled.

With 50000CPS, the differential offers high resistance to slipping. This means:

• Greater traction on acceleration, especially in fast corner exits.
• More stable and predictable behaviour, with less tendency for the inner wheel to spin.
• More direct response to motor power, ideal for circuits with wide corners or for drivers who push hard on corner exits.

In very technical circuits, with tight and linked corners, it may be beneficial to combine this viscosity with adjustments to tyres and guide to compensate for the more "rigid" behaviour of the differential.

Recommended applications

• Differentals of competition and club slot cars.
• Preparations aimed at maximum traction in fast corners.
• Fine-tuning the balance between agility and stability on the rear axle.
• Drivers looking to reduce inner wheel spin on acceleration.

Assembly and preparation

For optimal results, we recommend thoroughly cleaning the differential before applying the new silicone, removing any residue from the previous fluid. Apply just the right amount: excess can create unnecessary resistance and overheat the assembly. Check the manufacturer's recommendations regarding the filling volume of the differential.

If you are experimenting with viscosities, keep in mind that 50000CPS is a high starting point. If the car feels too harsh on traction or loses agility in tight corners, you can try lower viscosities to find the ideal balance for your circuit and driving style.

Points to consider

• It is not a universal lubricant: it is designed exclusively for the interior of the differential, not for gears, bearings, or axles.
• The viscosity 50000CPS is among the highest in the range; it is important to assess whether your track and motor setup can take full advantage of it.
• Results may vary depending on the specific design of each car's and brand's differential.

Frequently asked questions

What is the difference between using a low viscosity silicone and one of 50000CPS?

A low viscosity allows the axle wheels to rotate with much freedom relative to each other, which favours agility in tight corners but can lead to more inner wheel spin. With 50000CPS, the differential behaves in a more "locked" manner, transmitting more torque and improving traction, especially in fast corners.

Is it compatible with all slot differentials on the market?

The formulation is suitable for the common materials used in slot differentials (engineering plastic, brass, steel). However, we always recommend checking compatibility with the specific differential manufacturer, especially if it uses seals made from uncommon materials.

How often should I renew the silicone in the differential?

It depends on the intensity of use. In club racing with long sessions, it is advisable to check the differential after a certain number of running hours. If you notice that the car's behaviour has changed or that the differential is generating more heat than usual, it is a good time to clean and refill.

Can I mix this silicone with another of different viscosity to achieve an intermediate value?

Technically, it is possible to mix silicones of the same chemical base to achieve intermediate viscosities, but the result is not always predictably accurate. It is most advisable to use each viscosity independently and adjust based on track behaviour.

Does the differential silicone affect the wear of internal components?

Yes, positively: it also acts as a lubricant, reducing wear between the moving parts of the differential. A quality silicone specifically designed for this application prolongs the lifespan of the assembly.

The MP012-50000 silicone fluid for slot car differentials offers a high viscosity of 50000CPS, ideal for competition and club-level slot racing. Designed to optimize differential behaviour, it enhances rear axle traction, reduces inner wheel spin, and provides a more stable exit through fast corners. Compatible with standard slot car differential materials and formulated for long-term stability under friction heat.
