REPLACES OEM #’s  3211216 / 3211183

• 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.
