I just got a killer deal. I got a set of brand new crown hd leaf packs for next to nothing. They are the LS models though and not the LT's. If they were the LT's I wouldn't use the aal. See chart.

Spring codes


Springs, rear

LL - 3-1/8" free arch, load rating 405
LM - 5-5/8" free arch, load rating 605
LS - 6" free arch, load rating 675
LT - 7" free arch, load rating 755 UpCountry + 1 "

Dealer part numbers:

52000050 Standard Duty, Coded LB
52000051 Standard Duty, Coded LC, EC
52000706 Standard Duty, Coded LN, ES
52000544 Heavy Duty, Coded LK
52000545 Heavy Duty, Coded LL, EL
52000707 Heavy Duty, Coded LM
52002390 Heavy Duty, Coded LS
52002392 Heavy Duty, Coded LT ( UpCountry package +1” leaf spring)

Crown catalog list:
84/01 Standard Duty (LL ) 4 leaf - Jeep P/N 52000051
84/01 Heavy Duty (LS, ZGV, ZVV) 4 leaf -Jeep P/N 4886185
84/01 Heavy Duty (LT, ZGW, ZVW) 4 leaf -Jeep P/N 4886186 or 52002392 - UpCountry + 1”
84/01 Heavy Duty (LK ) 4 leaf - Jeep P/N 4886187
84/01 Heavy Duty (LN, ZUU, ZFU) 4 leaf - Jeep P/N 52000706
84/01 Heavy Duty (LM, ZGU, ZVU) 4 leaf - Jeep P/N 52000707

Question is, I have the 4886185's. People seem to use the 4886186's(UC replacements) and say they get 1-2" of lift. Should I use the RE aal I have to get the 2.5" that I want to have, or will I end up with A lot more lift?

I have ZJ V8 uc springs in the front. I just don't want to end up with bad vibe's or have a horrible rake. Think It will be ok?
