They are built to more rigid standards than original equipment and provide increased durability. Shafts and joints are forged from light-weight heavy duty 4340 Chromoly then receive induction and quench heat treatment for superior hardness. Although we have added improved boots and ultra-low profile boot clamps all remaining components are 100% interchangeable with stock which makes servicing a breeze in the event you tear a boot and need to get a quick replacement.
