B-drop differential spacers...and skid plate drop spacers....received....
C-rear set of 2.5 incons w/resi CDC on order...expect to receive in 5 days...
D-rear set of supreme add a leafs for 1.5 to 2 inches of rear lift....from Amazon....ordered today.. u bolts included....
E-Carrier bearing drop spacers...
F-2-1/4 inch spacers for the drivers side lean....
G-ordered passenger/driver side Mevotech adjustable control arms from geek auto parts but they emailed me said they only had passenger UCA and refunded me for the drivers side UCA....when I receive the the passenger side I will return for refund....
H-ordered SPC PASSENGER/DRIVERS adjustable UCA from Amazon....will receive in 7 days...
H- Rceived 5 ....275/80r/18 AT KENDA KLEAVER tires....on standby to put on after the lift install....

There maybe a few things I need yet...like maybe a shim for under the leaf springs....Things I bought but will not use....maybe....
2.5 inch Ready lift front spacers for the front and 1.5 inch blocks for the rear I bought earlier when first purchased the 2018 1794 3 weeks ago....so they are here and the front kit came with deferential and skid plate drop spacers..I should be able to use these spacers for the front end system of the lift....the question I have is can the spacers that came with the 2.5 inch lift be used with a 3 inch lift....or will I need to purchase longer spacers.....will there be that much difference between 2.5 and 3 inches of lift for the spacers....any ways thought I’d put this out there for the forum gurus who have a lot more experience than me....maybe the more experienced members can chime in and give their expert opinions....it’s sunny here in puget sound pierce county....filed my federal income taxes today....and filled the tank at Costco....and getting ready to have my canopy painted....here’s to all the working class hero’s....making a difference for our community and our families.....much respect....peace...
