I want to lower the rear to level the truck,,,,,,,but how???

Postby Mooner3347 [OP] » Sep 29 2012, 3:31am

I know most people level their truck but raising the front, but I want to lower the rear to make the truck set level. I crawled under my truck and saw that there is an 1.5-2 inch block that can be removed from between the axle and leaf springs. I am also familar with lowering shackles. My question is which would be better? By better I mean which would not affect the level or alignment of the drive shaft? I do not carry heavy loads and I would like the truck to still ride smooth. Any other things that I should be worried about ? Any tips from someone who has done this to their truck. My truck is a 2012 Sierra Crew cab 2wd.

Thanks for any input.

That block is an isolator to keep the leaf's away from the axel, you can take it out but you may hear like a clicking or shifting noise when you go over bumps, your best bet is going to be the new shackles

Drop shackles for sure! About $40-$50 and easy install...

If I use shackles does that change my ride quality or how much I can haul? Should I be concerned with the drive shaft angle changing where it meets the rear axle?

No adjustments are needed. I used adjustable shackles and used the top hole leaving about 1" of rake on the truck so I could haul light trailers.

Remove the block and as long as you get everything tight you won't ha e any problems..if you decide layer on that you may want to go lower then get shackles..no sense in spending money you don't have to spend when you can pull the blocks for free..putting shackles on and leaving the blocks will actually effect the pinion angle more than pulling the blocks, pulling the blocks will just allow everything to sit straight down 2.25" whereas shackles push the rear of the leaf spring up and will put the rearend at more of an angle..not saying shackles are bad but pull the blocks first

I'd do shackles only first. Make sure you lower the truck off the supports and it's sitting under its own weight before fully tightening the shackles down.
