A quick video of my Sterling's axle wrap on my commute to work.

 

Leafs look pretty weathered. JS

 

With the amount of salt we get in the winters, everything looks like that.

 

The block makes for a long fulcrum.

 

That came with the truck when I bought it. I suspect it's part of the mystery lift the previous owner put in.

 

Looks like you could use a EXTRA LARGE pinion snubber. lol Or you can install 1/2 a leaf in the spring pack.

 

looks about like 4" of block, looks about normal to me for that size block. the more it wraps the more resistant it become because the overload comes into the picture and really helps resist it.
Youve got three options to keep your height,
1)put in heavier rougher riding leaf via an add - leaf or add leaves from junkyard pack, which should enable you to reduce block size and resist wrap better. Probably the simplest would be a short 2" add-a-leaf just above the overload pack, which will give you about 2" of lift and you should be able to swap to about a 2" block.
2)install one of the many ladder bars out there, keep in mine the bars that have a 3 point connection and do not have a slip joint in bar or shackle at frame in bind the suspenion. But all of them really help put the power to the ground
3)reduce your power

 

Ladder bars are good but keep in mind they are hard on your springs.

 

Why do you say that? I have never heard this, and I have had traction bars on my truck for 3 years, no problems with the springs.

 

Not sure it's worth fixing, but ladder bars. This is the way.


Also the lower shock mounts look beat, lots of movement there. You might appreciate new shocks.

 

Yeah, I noticed that too. One more thing on a long list of things to fix.
