So Ive decided to make my own 1inch body lift blocks for my 92 4runner instead of using 4crawlers, my only question is what size/length do the new grade 8 bolts need to be? Does anyone know if the stock bolts will work with a 1 inch body lift? Thanks.

 

Maybe measure the factory bolts and then get new ones that are 1" longer?

 

^^^ this.

 

the 4crawler price is pretty good, especially if you factor in the material and time to make your own blocks. I'm like you probably in that I like to make as much as I can myself, but sometimes it takes longer than just buying pre-made kits in some cases.
