well, i did not have a good experience with National. Actually they are the highest priced ones. Also before ......i called them about shocks, they said they have these, my friend on the way home went there, they couldn;t find them, i ended up with two superlifts and two skyjackers- and some of these pins (2) missing, he waited there for an hour and 10 mins, LEE made a misteake. Sent my other friend there, they sold him wrong shocks, went there second time, got 4 replacemets, and one of them was fu***d, got that one replaced, recently he ripped one off and bent it, went there with a part number from that bent shock, they said that this is no longer in stock, and that a different number is available, got it, it was too short. Called and spoke to WES or Les or whatever his name is, ordered 4" RE Leafs, got these, came home installed them, called him about something, he said these were 3.5s not 4", one of them sagged about an inch, he said before that they were pre-sagged. Got my TCase rebuild by Ryan there, when installed and correctly setup the linkage made a grinding noise-never worked properly in 4x4-sold the jeep. Ordered axle seals for amc 20 for my GFs Cj, got wrong seals. I just can't deal with these people. To me they are a bunch of hicks and morons.
