Precision Diff Tuning with HUDY 106441 4000 cSt

HUDY 106441 is a premium 4000 cSt silicone oil aimed at hobbyists who want consistent differential performance. Made in Europe and quality verified, it helps maintain repeatable behaviour across sessions.

4000 cSt Balances Grip and Response

This viscosity level offers a compromise between grip and diff response, improving traction without making the drivetrain overly stiff. It suits a variety of track conditions and driving approaches.

Colour Coded Labels for the Workshop

Bottles feature clear colour coding so you can pick the right viscosity quickly while working on multiple models. The 100ml capacity is convenient for regular maintenance and tuning.
Remark :
Due to limited stock availability, please notice that some HUDY items may have to order from the factory and the ready time is around 8-12 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is this oil compatible with sealed diffs?

Yes, it is suitable for sealed gear diffs used in many RC cars, but always confirm with your model handbook for any seal material constraints.

How does 4000 cSt compare to 2000 cSt?

Compared to 2000 cSt, the 4000 cSt fluid is thicker and slows internal diff movement more, which can increase traction but reduce quick response.

Can I use HUDY 106441 in vintage models?

You can use it where dimensions and seals match modern diffs; for older kits check for compatibility and perform a small test run to verify behaviour.

What signs indicate the oil needs replacing?

Look for changes in traction, grinding noises, or visible contamination when you open the diff. Any loss of consistent handling suggests a service is due.
