PBX/TBX belts are made of a compound reinforced with aramid fiber, which does not stretch under load. The TBX Platinum strap will take you anywhere in any conditions. Specially designed for high power engines.
The belt achieves similar or better results than the original belt. You can replace the PBX/TBX belt with the original belt without changing the switch settings. It is good to always run in a new belt, this way it will last significantly longer.
