I've been pricing 4in kits for my K-30. I was going to go with rough country but they say they dont carry stuff for tonners. All the other places say the only ton products I can get are skyjacker or superlift. the best price I've found is 4wheelparts they want 530 bucks for a superlift-frt springs, all hardware, rear blocks,4 shocks and a steering block. And they're only a few bucks cheaper than the other two who have skyjacker. Am I looking in the wrong places or what? Once again, I thank you, 4-wheel gods, for your help.
