I'm assuming you've actually owned a said RC kit right? You're not just regurgitating the standard RC hate found on here?
Funny how these kits have worked just fine for me....and many others.

I haven't had to replace one bushing....but i actually grease them when i go wheeling. Basic maintenance does wonders for them i guess

I'm with you on this one. No problems with mine.

Since you mentioned TNT specifically, I've installed one on a 4.5" lift. While it is a great set up I had to trim the inside of the frame rails where the stock LCA location is. It was contacting the arms on compression. After that the driver had no further issues.

The springs suck the shocks are garbage. Everyone I know has had issues with bushings. Theres a 4.5in rc kit on my truck now. It came on my truck I did not buy it and I cannot wait to throw it in the garbage.

i have an RC leafs and tracbar. i am very happy with the overall lift, but i do not go offroad at all. so speaking from a mallcrawlers pov, my only complaint is... i only have about 250 miles on my lift and the ball joint boot on my TB is allready cracked.

Its been a 1yr 1/2 since i got the the TB but it sat under my bed that whole time and RC won't warranty it. now its gonna cost about 30-40 bucks to replace it. no big deal i guess, i know its a wear item, but i wasn't expecting an item to wear out in 250 miles. wtf. but its just one ball joint.waahhhh...lol

but i do love my lift. RC and IRO combo. it maybe stiff but it won't sag as a mallcrwlr...lol

so you're crying about some old RC kit that was already put on your truck you didn't pay for and who knows how it was taken care of? on top of that everyone you know cries about their RC kits? sucks to be you don it?

The kit on my truck has maybe 5k on it the shocks are already starting to go. Idk why your attacking my oppinion on theyre junk. Its obvious they have had more then just me that have had problems with there parts. There are better kits out there for the money, or piece together your own kit off the forums for a lot cheaper.
