Quality product eliminates steering wobble and fits my 05 F250 FX4 perfectly, not that heavy (much thinner cylinder and piston than Rancho OEM) but still works well. After several months of use, the only problem is that the rubber bushings are badly cracked. I can't fault Monroe or the seller as some of the products I bought here seem to be old, I can't complain about the savings here. In any case, the plan is to replace the bushings with polyurethane, and this is an inexpensive solution.
