I stumbled upon internal shock limiting early in my first year of racing. My rear A-arms where traveling so low that my CVDs were popping out of the drive cups. Instead of shimming the CVD closer, I just limited the down travel of the rear suspension. Little did I know that it would change my setup world permanently.  I figured it helped dramatically in the rear, what would it do in the front as well? Holly shit.... I went from mostly C-mains to upper B-mains just... like... that!!!

Here's a picture of how I limit the rear shocks.

I just use the old left over spacers from the shocks after I rebuild them.

These are only the rear shocks, I usually do all 4... I'll get some better pictures up while I rebuild my shocks when I can find time. As you can tell I just took them apart to show a friend a couple years ago. I'd have them very clean if I were going to rebuild these shocks or would have needed them anytime soon.

This is how I put them on. Most of the time I use 3 spacers in the rear or that black spacer to the left, then 2 thin ones up front.

1 black in the rear and 2 white in front, reduces body roll on these smooth/tight high traction tracks. Heavy braking entering U turn.	Same limiting, same track.... Fast tight corner inside line a must.	As you can see, the limiting works great in this tight turn at the bottom of a jump, very little body roll. My truck is in the back.	With 2 white spacers in the rear shock and 2 up front, I still have plenty of suspension while keeping the inside tires planted in this fast sweepR .	This is one of my trucks without the internal shock limiting. Way to much body roll for this track.

I must add that I'm not an expert at setups, actually I'm far from it. As far as I can tell, internal shock limiting mainly forces the inside wheels down in turns thus reducing body roll as well. There are other ways to reduce body roll without internal limiting such as camber link adjustments..... which I had no luck finding a different setting than stock that worked for most tracks like internal limiters do. I also found that some body roll can be a good thing so don't try to eliminate all roll but I'm not going into it here.
