The Primo offers replacement belts in two different resistances, an HTD for normal use like the one provided in the Primo kits. The other belt is in Kevlar, much more resistant compared to the standard one for the different internal weaving. Kevlar belts are recommended for use on powerful large-displacement engines and are obviously used on Ton Pels' primary dragster of over 600 HP and many others.
