you should call them they'll let you know what the deal is.

 

My book says R3415 for rear add a leafs for 2wd and F432 for front scoils. The entire kit is F4321K.

For 4wd they don't list seperate parts.

For 4wd and 2wd 6" lifts the rear replacements springs are both the same part #FR45S.

Since the 6" rear springs assembly is the same on both 2wd and 4wd why wouldn't the add a leafs from the 2wd system work for the 4wd system?

 

I thought on the 6" 4wd systems, they replaced the entire rear leaf springs...not just added a leaf or two

 

Sounds like what I just said.
If the rear assembly is the same on 4wd and 2wd 6" lifts then why couldn't the add a leafs work on 2wd and 4wd's?

 

heres an update. i did my alignment today and the upper a-arm ball joint seems to have moved out quite a bit from the spring.

 

 

that angle does look radical although its hard to tell in a picture i imagine if skyjacker gets alot of complaints they'll come up with a new knuckle to solve any issues the truck looks awesome

 

How much did it cost you? and where did you buy from?

 

i bought it from www.4wheelcustoms.com talk to Chris Darnell. that dude has helped me out a lot. tell him Erick sent ya some business! i got the kit for around $650 shipped with new Skyjacker shocks out back which the kit does not come with.
