About this product
Fine-tune your radio controlled car’s handling with Kyosho’s premium silicone damper oil. This 40ml bottle of 4000wt fluid is an essential tuning tool for any RC hobby enthusiast looking to optimise differential performance. By adjusting your damper oil weight, you control how much your differential “diffs out” through corners, directly affecting how your RC car parts work together. Thicker oils reduce differential slip for more predictable cornering behaviour—making this one of the most impactful modifications for off-road buggies.
