replacin stones wit slams

I'm currently runnin 2500's on the front and 2600's on the rear of my ranger. I wanna switch to slams for more lift and i heard they were a better all around bag. My 1st ? is whats slam that equivalent to each of those and also whats the mounting pattern on em

re6's are the same size as 2500 and the re7's are the same size as 2600

That sums it up...

i'm unfamilar wit slams, when it says size 6" 7" 8" which ones would be best for my application?

dude he just told ya, the 6s are equiv to firestone 2500s and 7s are equiv to 2600s. but if you can fit the 8" in the back go for it, more lift.
