When it comes to adjusting your variator, there is no need to buy tons of roller weights to find out optimum roller weight. This roller weight tuning kit includes several weights to adjust and fine-tune your variator. You can combine 2 sets of rollers, this allows for a large variance of weight settings. The kit includes 4 sets of different roller weights and 1 set of shells. Available for all variator models. Note: these rollers are meant for tuning purposes only, not built for permanent use. Once the optimum weight is determined, you should get a regular set of roller weights.
