Tonight I playing around with the height of the front end on my Charger. I was attempting to raise the drivers side another 1/4" to equal the passenger side and all of a sudden KABOOM. The threads totally stripped out of the block. Luckily nothing on myself or the car was damaged. These were about the only things that I didn't replace on the front end of the car, and now it comes back to bite me. So I am wondering if all replacements are the same, or are some better? I see Jegs and Summit have the same order #. Mancini has a different one. Any other recommendations on where the best place to buy a pair would be?
