Standard HTD® has been the leader in the new generation of high performance curvilinear synchronous belts. First developed in the early 70's, it has been continuously improved through the years. Its neoprene and fiberglass construction have proven extremely durable for virtually all racing applications (with the exception of alcohol and fuel classes). This belt can be back-bent.

Power Grip GT2® is an improvement over the HTD belt. It is a rubber belt with a fiberglass tensile member, neoprene backing and teeth and a tough nylon facing for low friction and wear resistance. This belt has excellent flex life, high resistance to elongation and good length stability. This belt can be back-bent.

POLY Chain GT2® A second generation Poly Chain product has a patented tooth profile which substantially improves stress distribution. In addition, it incorporates the latest urethane and aramid materials technology for the tensile member, coupled with a completely new manufacturing method. These materials have very high modulus and tensile strength. This unique product has horsepower ratings up to four times that of its rubber counterpart! Its high impact strength withstands extreme shock and surge loading. The result is a product superior to anything in its class -- without exception! This belt has been widely accepted in the fuel classes as giving superior performance compared to any other belt.
This belt should NOT be back-bent.

Poly Chain GT2® (PS Series) The newest generation Poly Chain belt developed exclusively for Top Fuel cars but may be run in any class, for those demanding superior performance. This new generation Poly Chain uses a modified core construction and materials used in the proven Poly Chain predecessor. Tests on championship race teams have shown an increase in reliability and the ability for more runs per belt, reducing overall belt replacement costs. The result ia a product superior to anything in its class - without exception!
This belt should NOT be back bent.

Poly Chain belts are lighter than the HTD and Powergrip belts providing less rotating weight and less centrifugal force on the belt. This translates into more strength in the belt to drive the load.
