I recently replaced the stock F bars that were sagging somewhat after 165k. I used as a replacement, Class 1 Torsion Bars and when torqued to the max I got 2.5 inches of lift. Enough to get new 31-10.50-15 Michlien LTX AT tires to fit with no problem at all. Everything clears by a pretty wide margin. But The rear of my truck needs to be elevated to match the front height and maybe 'bout another inch over that. I like a little "rake" on my trucks. I am not too "shot in the head" with the idea of exchanging rear springs. My question is which would be the best...Blocks or Shackles...and why. Anyone got any information or input to help solve this minor problem as to which option would work the best. I figure a few heads are better than just mine.

Another question...I'd also like to add to the width of the running gear as well...I like the stock aluminum wheels and I ain't looking to buy a new set of wheels. How would wheel spacesrs work. I'd use 3/4 inch spacers on all four corners. My main worry is how much extra strain 3/4" spacers might effect the life of my front wheel bearings.

Thanks..

 

Get shackles, blocks will cause more axle wrap.

You could use spacers until you save up money to buy new wheels down the road. The stress that spacers create isn't very noticeable when using spacers less than "1
