coil spring question

i have a 99 tj that has bad stock coils.a 4wd dealer i talked to said i can put in a 2"spacer kit that includes shocks and bumpstops.he has a 2" taller coils that i can get but i have to get shocks,bumpstops,trackbar bracket,tcase drop, and swaybar links.he said i wont need the track bracket,links and tcase drop with the spacer kit.
my question is if i get a spacer kit dont i need the rest of the stuff??and if a 2" taller spring is same height as a stock spring and spacer,cant i just get the coils and shocks without getting the rest?

thanx,
steve

i think he might have fooled you cause either way its 2 inches of suspension lift so why would you need some stuff on one lift and not some on the other? the pro comp lift that replaces the coils comes with just the 2" longer coils and new shocks and thats it...either way your getting 2 inches of suspension lift so you might or might not need the t case drop...if you don't use one you would probably just have very slight vibes at the most...i don't see why you would need all that extra stuff with either kit...all ya need is shocks, bumpstops, and the spacers or new coils...and sway bar links are optional along with the t case drop...you should be able to get just the coils and shocks without getting the rest...that is the way pro comp sells it (along with a couple other manufactures)

you should be fine with that...i know right off the top of my head, 2 manufactures that make 2" lift kits with JUST the new springs and shocks...the only thing you would need that it doesn't include is maybe new bumpstops (?)...you shouldn't get much vibration with only 2 inches and you shouldn't need the new links

most tj's won't experience vibes after a 2" lift -whether with spacers or with 2" springs. it all depends upon your drivetrain combo though. the touchiest of combinations seems to be the 4.0, nv3550, np231, and d44 axle. that combined will yield the shortest rear driveshaft and allow the vibes to develop with the least amount of lift.

most people, when they experience vibes, will install the 1" transfer case drop and never look back. but with only a 2" lift, they are just entering the realm of vibration...and can usually alleviate the vibes with only a 1/4" to 1/2" of drop. i would try placing a washer or two in between the transfer case skidplate and the frame before installing the full drop. this way you'll only be lowering the skidplate as much as neccessary instead of losing the full 1" of clearance.

the 4wd dealer may have been trying to say that by installing the 2" spacers on your jeep you would only be around 1 3/4" height over your jeep's stock height (remember, your current springs have sagged) and possibly not inducing the vibes. the new 2" springs, however, would lift your jeep a true 2" over stock height and putting you in the area where you may starting feeling vibes.
good luck with it!
