  • SR VIPER ALL MODELS (2014-2022)

Replaces OEM # 8JP-17641-00-00


Built to decrease the chances of snapping or delamination in race applications when the tendency is to land on the throttle.

Manufacturing, quality control certifications — ISO-14001, ISO-9001, and IATF-16949.

Newly released design that has a larger Kevlar cord with a custom braid design to act as a shock absorber.

New vulcanization process to marry the layers of the belt together around the cord preventing premature separation of the layers.

Custom blend of two premium High Modulus Compounds holding the top layers together with the cord and bottom layers like super glue!

Highest shock load rating to date being able to withstand the power of the 600hp machines.

Increased top cog pressure load design that increases sidewall rigidity, prevents top cog bowing, but still allows for increased rotational flexibility.

Bottom cog uses HIGH modulus rubber compound (BZX1) for better heat resistance and heat dissipation.

Impregnated with short Aramid Fibers for better belt-to-sheave adhesion and reduced overall belt temperature.

Latest bottom cog design for greater rotational efficiency at full shift.

Precision ground sidewall angle (SCUFFING) for smooth engagement, increased power transfer and lower operating belt temperature.

Kevlar cord, versus polyester, wraps over bottom cogs for increased bottom cog strength.

Increased cord pop-out resistance.
