The RCD kit is a drop bracket kit also.ck.The "coil" overs thats look to come with the kit look like someting of a stock car/roundy round car.atleast in these pics.Have seen a few on the street that were just bilstein 5100 type of shocks with a coil spring stuck on them.More like a strut if you ask me than a "coil over"
this kits runs ruffly 2500....
the super lift kit, is anouther drop bracket kit.but you keep your T bars,
you can find alittle more here on TRS, in the techlibary, link at the top of the screen, then got to 4wd lifts.
for about a grand more total, you can get the dixion brother's kits.The only true performance kit I know of for the A-arm rangers.

for the shocks/coil overs you could always go with FOA to keep the price down vs the FOX shocks.This kit would give you a much better resale value of your truck too over all....

AS for ford warrnty, its all up to the dealer for the most part.some dealers are cool and relax, some are just shity.The extened warranty is were it can become a nightmare.As the companys the hold the warranty can be real nit picky.There is were a cool dealership can really help.And push for you to get your truck fixed. Ive been there.........my advice is to spend a day across the street and watch the truck that come in to get serviced.IF you see lifted trucks, modified mustangs and such, you got a really good chance of a cool dealer.....if you see nothing but stock factory cars and trucks.....your changes are not as good.
like the dealership down the road from me, they dont care what you have done within reason.....the one on the other side of town, will try and void your warranty for a bug shield.
