Replacement HTD kevlar reinforced internal supercharger drive belt. This is the correct tooth pattern for Powerdyne internal drive belts. This belt is 3mm wider than the original design for more strength. No internal modifications are required to use this belt.
Note: Gates has discontinued the original and the replacement belt for this series and will not produce it anymore citing too low of volume. We have found another manufacturer and will be selling this belt as a replacement.
Note: HTD belts feature a half moon tooth shape. This is the correct belt for JB Performance replacement shafts and for original Powerdyne Shafts. Other venders sell a GT tooth pattern which is made for a trapezoid shaped tooth pattern. These are not the correct belt for original Powerdyne shafts.
If you are having issues with belts breaking, the supercharger is mounted to an engine producing more torque than it was designed for, it is being overspun, belt over-tightened, or there is internal damage that is being over-looked.
