If I was 2wd I'd be all over spindles, but with a 4x4 you can't do anything with the front except max the t-bars unless you buy a lift kit or keep your suspension stock and just do a body lift.
I couldn't be bothered to do any of that and my truck sits high enough for my likes. It has too many miles on it for me to start throwing money at it for mods. I just went with the drop shackles because I had a broken shackle and for the price of the chevy ones figured why not?
Looks good man. Once i upgrade to 1 bars ill be crankin them up and putting shackles on as well on top of my body lift. I currently have B bars and they are maxed and i don't even mind the ride i got 33 MTs too. when i maxed my bars i still had my 31s on the truck but i got it aligned when i did it just because i didn't want my tires wearing...just in case
