Malossi HT-Rolls Variomatic Weights 19x15.5 mm (5.7 g) – precise variator rollers for clean tuning

If you want to fine-tune the adjustment of your variomatic, the Malossi HT-Rolls variomatic weights are a truly reliable choice. Malossi has been known for decades as an Italian tuning forge focusing on quality, performance, and precision – and that is exactly what you notice immediately with these rollers.

The HT-Rolls are made of a highly wear-resistant material and are extremely precise in dimension and weight. This makes the variomatic run more smoothly and reproducibly – perfect if you value consistent results in your setups. The slightly higher price pays off quickly because the durability and better gliding behavior provide long-term peace of mind.

Important: The Malossi weights are used without grease, as the surface is self-lubricating.
