Lowering Blocks

[andrewpayne83]

Does anyone have any experience or knowledge on using lowering blocks on a 2 door 2 wd Tahoe, if so I could use some information or recommends on what exactly I’m needing
Thanks in advance

On GM trucks, the rear axle is under the leaf springs. If you install a set of blocks, it will RAISE the truck.
So, no. No one has experience with "lowering" blocks on a Tahoe.
If you want to lower the truck, there are many options:
Longer shackles
Lowering front leaf hangers
Axle flip kit with a C-notch

Maybe he's coming from the S10 world.... I think they're spring under, rather than spring over.

Perhaps...
S & T trucks are indeed "spring under".

Once you've flipped the axle blocks will indeed lower the vehicle.

It already has the flip kit and c notch on the truck, I am looking to get one more inch in the rear and lowering shackles will not work on a Tahoe with the gas tank being in the rear

How about replacing the forward leaf hangers?

And yes, some folks do have experience with lowering blocks on these vehicles...
I had a set on a C3500 dually a few years ago, but I didn't install them. I'd assume you'd need longer U bolts, and possibly shims just like you would if you were lifting it.
