Silicone 3000CPS SPECIAL DIFFERENTIALS

The right viscosity to get the most out of your differential

When we talk about tuning in slot racing, the differential is one of those elements that makes the difference between a car that skids in corners and one that accelerates with precision and confidence. The Special Differential Silicone 3000CPS (MP012-3000) is formulated with a medium-high viscosity that allows for controlled adjustment of the differential lock, without overdoing it or falling short.

Function and performance

The silicone for differentials acts as a means of torque transfer between the two rear axles. The higher the viscosity, the more resistance to relative rotation between both wheels, which translates into behaviour closer to a locked differential. With 3000CPS we find a very versatile midpoint:

• Increased traction in fast corners where the car tends to skid.
• Reduction of free rotation of the inner wheel, especially useful on tracks with tight radius corners.
• More predictable response under hard acceleration from the corner exit.

Compatibility and applications

This silicone is compatible with the common ball or oil differentials found in competitive and modified slot cars. It is easily applied thanks to its fluid yet consistent texture, and it does not damage plastic materials or the internal seals of the differential.

It is especially suitable for:

• Cars with Sidewinder mounting (motor parallel to the rear axle) where the differential works intensely during braking.
• Tracks with many hairpin or tight radius corners.
• Drivers looking for a traction point without reaching total differential lock.

Assembly and preparation

To achieve the best results, we recommend thoroughly cleaning the differential before applying the silicone, removing any residue of previous oil or dirt. Apply a small amount inside the differential, assemble and turn several times by hand to evenly distribute the fluid before reassembling the car. The amount directly influences the level of lock: more silicone, more resistance.

Common mistakes

• Mixing viscosities without cleaning: if you combine different silicones without cleaning the differential, the result is unpredictable. Always clean before changing viscosity.
• Applying too much: excess does not improve performance, but can cause leaks and dirty the inside of the chassis.
• Not doing progressive tests: the ideal behaviour varies according to the track and driving style. Start with a small amount and adjust according to the results.

Frequently asked questions

What is the difference between a 1000CPS silicone and a 3000CPS silicone for differentials?

The viscosity determines the resistance to relative rotation between the axles. A 1000CPS silicone is more fluid and produces less lock, ideal for fast tracks with wide corners. The 3000CPS offers greater resistance, improving traction in tight corners at the cost of some agility on fast layouts.

Is it compatible with all types of slot differentials?

Yes, it is suitable for ball and oil differentials commonly found in 1/32 scale slot cars. It is always advisable to check that the differential is clean and in good condition before applying it.

How often should the differential silicone be renewed?

It depends on usage and track conditions. In regular competition, it is advisable to check the differential every few intense sessions. In recreational use, a periodic check each season is usually sufficient.

Can I use it on cars with Inline or Anglewinder motors?

Yes. The silicone acts on the differential regardless of the motor layout. Both in Inline configuration (motor in line with the rear axle) and in Anglewinder (motor at an angle), the treatment of the differential follows the same principles.

Does it affect the plastic or other materials of the differential?

No. The formulation of this silicone is compatible with plastic materials and the seals commonly found in slot differentials, without causing swelling or degradation.

The MP012-3000 differential silicone fluid with 3000CPS viscosity is a precision lubricant designed for slot car differentials, offering optimal torque distribution and traction control. Compatible with ball differentials and oil differentials in 1/32 scale slot cars, it suits Sidewinder, Inline and Anglewinder setups. Ideal for club racing and competitive slot car preparation, this medium-high viscosity silicone helps reduce wheel spin in tight corners and improves throttle response. A reliable choice for slot car tuning, differential setup and performance upgrades.
