Malossi HT-Rolls Variomatic Weights 19x15.5 mm – 7.2 g for clean variomatic performance

With the Malossi HT-Rolls, you bring proven tuning quality from Italy to your variomatic. Malossi (traditional Italian company and well-known tuning house) has always stood for quality and performance – which is exactly what you notice with these variator rollers: they are made from a highly wear-resistant material and impress with extreme accuracy in dimension and weight.

The slightly higher purchase price quickly pays off: through the longevity and the better sliding behavior. Practical: the weights are used without grease, as the surface is self-lubricating.
