Malossi HT-Rolls Variator Weights 15x12 mm – 8.7 g for precise tuning & long-lasting performance

If you want to tune your variator cleanly, the Malossi HT-Rolls variator rollers 15x12 mm with 8.7 g are a top choice. As an Italian tuning specialist, Malossi has been known for quality and performance for decades – and that is exactly what you notice with these variator weights.

The rollers are manufactured from a highly wear-resistant material and score with extreme precision in dimension and weight. This ensures the variator runs consistently, the tuning remains stable, and you benefit from better sliding behavior. The slightly higher price pays off quickly through its longevity.

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