I purchad the ironman spings from a company going out of biz for 500 dollars. When it was installed, it was hard as a rock. I did not know it at the time, it was for a hj60 diesel, not the bj60. So I suspect there was one or two more added to each corner pack making the truck extremely stiff. How stiff? How about loading 800 bls of cement in the back of my truck and the rear dropped a inch.
It has been a number of years now. I have lots of gear in the back of my truck weighing it down and the springs still running good. I should however, take them off, clean them up, paint them then lube them. The springs have never been lubed with molyb before.
