Shackle purchase price for rear 2.5 inch lift

I was researching shackle prices and wondering about build quality.....price.....there are some vendors that offer less expensive shackles than the more popular higher build quality expensive shackles....so far I’ve purchased icon 2.5 reservoir...compression adjustable struts....mevotech/SPC adjustable UCA.....and need to purchase shackles rather than blocks for the rear lift.....I also need to purchase the differential drop spacers....drive line drop spacers....and brake line extensions brackets.....what am I missing....I know there are other drop spacers I need to buy to bring suspension parts into alignment but I can’t think of them....oh yes ....I also purchased bigger tires......275/80r/18.....I will probably need to determine how I’m going to fit those gigantic tires into that small wheel space after it’s lifted....the icons 2.5’s will lift a maximum height of 3 inches in front if needed....I’d rather not....I’d like to stay in the 2.25 inch range if possible.... but I’m getting closer with gathering all the supplies needed to do a safe and reliable lift....my next big search will be a dependable reasonable installer.....someone mentioned a vendor in Bonney Lake....pierce county Washington .....so I’ll probably phone or visit that shop for an estimate for install....Can any members advise me of the expected install costs for this set up....oh yes I plan to purchase the icon rear reservoir with CDC piggy back for the rear shocks.....which I’ll install myself....next payday or sooner....anyways....thank you ....peace....
