3" rear blocks
Who has installed 3" blocks in the rear and what was your experience?
I've been working out of town for a few months and have scraped up a little extra money. With that said, I would like to add a leveling kit and rear blocks to my truck when I get home. I'm aware that adding blocks will increase axle wrap when accelerating hard, but I rarely tow and really don't beat on my truck that often.
Any advice would be appreciated.
Thanks,
Q.

Put them on my 2009 myself. No problems, either with the install or function.
But neither did I ever launch/stop hard with my 33" Terra Grapplers, nor with a massive trailer behind it.
Unless you're putting down some serious instantaneous horsepower, short gears, and massive traction and/or tow, I doubt you would experience axle-wrap issues with 3" blocks and otherwise a stock performing truck. And with near-stock size tires, most likely your tires will lose traction first before axle-wrap becomes a concern, especially with an unladen bed.

I believe they are 1 1/2" blocks on the 4x4.
Thanks for all the info.... I would consider my truck to be underpowered so i'm sure I won't have much of an issue and as my wife say "I drive like an old man"

Stock blocks are 1-1/4". I just measured mine to verify.

Got mine from ebay. Cast Iron Rear 3" Lift Kit for Mark Lt F150 04 14 4WD Free Shipping | eBay I paid $70.00 for them at the time. There are also some others listed. I chose to stay with the OEM cast iron design.

Well this is what I have in mind for my truck when I get home. I'm still going to look at other steel leveling spacers because the one I have looked at doesn't say what kind of hardware they use.
what do ya'll think?

What you see underneath the new block is the axle mounting pad that's welded to the axle tube itself.
