Does anyone have experience with Currie's High Pinion Ford 9" rear axle? I'm thinking about replacing my rear Dana 44 with Currie's High Pinion to reduce drive shaft angle, increase pinion ground clearence and easy conversion to disc brakes. Is their High Pinion suitable for highway use or is it strickly for off road? I'm sure if I call and ask them they'll tell me it's like mothers milk. If anyone has any experence with one of these units please let me know.
