I have 285/75/16 BFG MT tires, would they be to small if I put on a RSK? Also, for people who do the RSK, what do you do for the rear? Blocks?

Thanks!

I don't think 285's would look too small after doing an RSK. I have 35's, and I like that look, but 285's aren't that much smaller.
When I did my RSK, it lifted the front about 3", which was slightly too much to level the truck. I'm lucky and have air bags on all four corners, so I just put 30psi in the rear bags to give me the stance I wanted. Others have installed bigger blocks, or installed an add-a-leaf.

How big of blocks would I need for the rear if I did the RSK in front?

f250 come with 2" blocks I think, and f350 comes with 3". You can add a 3" block to the f250, or 2" to the f350 to level it out.

Cant remeber the exact details above.. sorry. I do remember that the stock blocks between the f250 and f350 are definately different. So playing around with add in blocks and stock blocks, you should get the appropriate lift.

The blocks on a 250 are 2", and on a 350 they're 4". If you get 3" out of the RSK like I did, you'd want to go another 1" to level it, or 2" to give it a slight rake. By adding a little air to my rear bags, I've given mine a 1" positive rake.
