Break the lugs loose while truck is on the ground.
Jack up the rear end and place jack stands under truck.
Chock the front tires.
Remove rear tires.
Place lever jack under rear axle.
Disconnect the U bolts. 18 mm
Disconnect rear shock 19mm at bottom, 17mm at the top.
Remove brake and abs lines from holding brackets to free up some slack.
Ensure slack in diff breather mod.
Remove sway bar to get enough length when lowering axle to be able to remove overload leaf and install add a leaf pack.
Replace overload leaf with 3 leaf add a leaf
pack. Sticker should be facing front of truck, also the shorter end faces forward. 14mm bolts.
Will need to impact wrench leaf pack bolt to get leafs together then cut off excess bolt length in order to fit upper u bolt bracket.
Don’t tighten the small front and back brackets too tight on leaf springs, they are just meant to align the leafs.
Will need to drill out factory plate holes from 1/2 “ to 9/16” holes to fit aftermarket U bolts.
Paint bracket so the drilled holes dont rust.
Will need to bend new u bolts inward to fit bracket.
Install brackets and u bolts.
U bolt torque spec 54 ft/lbs
Sway bar torque spec 62 ft/lbs
Lower shock bolt 155 ft/lbs
After everything is reconnected put wheels back on.
Snug all the lug nuts then torque in star shaped pattern to 75 /85 ft lbs, depends on wheels honestly that’s just what I did on mine.
Good luck!!! 🍀👍
