G-BOOST TECHNOLOGY WORLDS BEST BELTS FROM ERLANDSEN PERFORMANCE ! IN A NUTSHELL THE EX IS HARDER COMPOUND AND THE WBB IS STICKIER BUT RUNS COOLER! THE WBB383 IS OUR BEST SELLER FOR THE 850 ETEC APPLICATIONS (WE DO NOT RECOMMEND THE DBSD383EX ON 850 APPLICATIONS) . THE WBB383 RUNS ALMOST THE SAME RPM AS THE 531 & 571 SKI-DOO BELTS IN MOST APPLICATIONS.
DBSD383EX SERIES FEATURES:
Ultra-strong Aramid Fiber cord that can handle/carry more than 10,000 pounds of tension without stretching or breaking.
Higher strength compared to OEM and aftermarket drive belts.
EX belts have been developed with a high-temperature compound called DUMAX for added strength, flexibility, and heat resistance which in turn means you can squeeze our belts a lot harder for more tuning possibilities and less slippage.
Maximum under-cord stiffness allows the belt to flex for rotational efficiency and running cooler temperatures
Built for high temps, extreme abuse, and excessive shock load.
WBB383 SERIES FEATURES:
Manufacturing, quality control certifications — ISO-14001, ISO-9001, and IATF-16949.
3rd Generation heavy-duty, high-twist Aramid Fiber cord for HIGH HORSEPOWER TENSILE LOAD requirements. Making it the strongest belt on the market, surpassing even our EX and Sand Storm lines.
Highest shock load rating to date being able to withstand the power of the 400hp 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 MODULOUS RUBBER COMPOUND (BZX1) for better heat resistance and heat dissipation.
Bottom cog is 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.
Aramid Fiber cord, versus polyester, wraps over bottom cogs for increased bottom cog strength.
Increased cord pop-out resistance.
NEW FOR 2021-- WBB383RS- RACE SERIES BELT- This belt is almost the same compound as the WBB383 but has much more Aramid Fiber cordage which can handle the massive force loads under hard acceleration af drag racing, snowcross etc. Clutch tuning is virtually the same as WBB383
