Here's the deal. I'm looking at purchasing the skyjacker lift from 4 wheel parts.com. I'm going 2 1/2" lift. If also been looking at MAF 2 1/2" lift. Cost about the same but comes with extended shackles all the way around. My question is, can I just pick up any extended shackle? I noticed SOR had some greasables on clearance. do I need casters? I would like to level up my drivers side rear lean as well. Can I just make a 1/4" plate shim out of sheet metal or would you recommend getting a pre-made shim from someone? Also, how good of quality are the shocks that come with the skyjacker kit? I keep hearing the right shocks make all the difference in ride quality. How about heckethorn shocks? Next the tires. I was thinking of 31x10.5 (know that sounds sissy to some of you guys) maybe 33's. I see 4wheelparts sells rims and tires in kits. Ayone done this before? Is the service & quality pretty good? Also what backspacing do I want? I don't really understand how that works. I was looking at probably 15x7 or 8" rims. but I want to make sure I don't get the wrong ones if I order online. Maybe I should just get them locally? I have stock rims that are 5.5 I beleive. Some people have said they have put 31 x10.5's on the stock rims but the guy at the tire store said you can't do it (maybe thats just because he had some ugly rims he was trying to sell. I'd probably prefer to keep my stock rims cause I like the look but am considering the rock crawler rims at 4wheel parts. Thanks in advance for any help. I know these issues have been talked about before. sorry.
