Anyone know what u bolts I need to just take out the rear block on my truck? It appears I’ll run out of thread before tightening.

The PN's I installed are:

2WD U-bolts ML3Z-5705-A (quantity 4)

2WD Bump-Stops ML3Z-4730-A (quantity 2)

I have a 21 SuperCab 8’
Everything should be the same
I removed blocks and installed lowering shackles (1-1/4”)
Longer shackles will require some bed trimming

Just did this exact thing a week after I bought my 23’ FX4. The stock Ubolts will work just fine. Block is about an inch and a quarter in height, more than enough threads left!

I'll eventually be doing this also on my 22 SuperCrew 5.5' 4x4.
My local dealer provided a quote, those part numbers are correct.
He also provided a part number for the hex nuts, in case new ones were wanted.
W520215-S440 (qty 8).

Shop online for this stuff.
Some dealers think those u-bolts are are made of gold.
My closest dealer wanted $50 apiece
Got them online for $28

If you think you might reinstall blocks one day just buy another set of 4wd ones for $8 each and cut 1 1/4” off. Price difference between the two is crazy.

well, that's just plain smart.
I wasn't gonna buy them from the dealer, just asked for correct part numbers while I was there for something else. I was going to shop on-line like @BryanSimon said... but now when I get to it, I'll check out the pricing for the 4x4 bolts.
Thank you gentlemen.

Well I probably should have just cut mine after reading this. I reinstalled my blocks and am now selling the 2WD Ubolts. They are on the members marketplace for 100 (I paid 170). If anyone is interested, let me know.
