So this is random, but if I got the rough country 6 inch lift, does it come with everything I need? Also someone told me I needed to re gear the truck on a six inch lift. True?
i personally do not like rcx. its not a true 6" drop. i also dont like their steering setup as well as their use of blocks, but everyone uses blocks, it just isnt correct. plus their salesmanship that caters to half assed 3" keys and upper controls arms on these trucks cases lends me to like them even less.
true leaf or a shackle flip in back would be best but theres some dependency on usage of truck. blocks taper the rear end toward the output of the trans so you dont need to lengthen driveshaft, this also however puts the u joints out of sync which without going into heavy detail isnt correct at all. most people are oblivious to it being an issue.
do you need to regear with a lift? well most times you add a lift you add a bigger tire, on a half ton heat is the enemy of your trans, more lift + bigger tire means more excelerated wear on your trans, the regearing is primarily for the addition of the larger tire. you could run the stock 265s on a 6" lift and it wouldnt require it although it would look goofy. google Grimjeeper calculator and it may be a good reference point for you to figure out final drive ratio when adding and changing things such as tire size.
back to lifts. RCs is a 5.25 drop and at stock bar height is around 4" their same kit for the 6" comes with keys or some crap for your instance where the bars are so heavily worn you can crank it back. the problem with keys on already worn bars is once sprung steel is past a certain point of deforming its will just excelerate its wear even faster so those bars are junk. step 1 would be replace your torsoin bars if you plan to do things correctly. If not be like the other 90%, and be numb to it not being correct, seems to work for alot of people or so you see on the internet.
zone is essentially a BDS lift, or was, its been awhile since ive looked at current market lifts. Superlift wasnt bad, their old kits had alot of pieces were kinda jank. theres fabtech which is a knuckle lift, i think full throttle is still around, procomp is still kicking. 10+ years ago there was a half dozen other brands around.
body lift wouldnt mess up anything but linkages, replacing your worn torsoin bars would be a good starting point in general. usually you need to source from the junkyard, sway away used to sell them but they were expensive. there is some interchange with newer trucks from what i recall but do some research, theres different rates that will affect ride and so forth.
