Transfer Arm Lift

Can I install a 4″ lift block on the front of my 1990 full size Chevy Blazer?

I plan on adding a better sway bar, dual stearing stabilizers and a lowered control arm.
I already have a 5″ spring kit, extended brake lines, dropped transfer case mounts.
I own a set and plan on running 38 x 12.50 x 15 Super Swampers on it

Do Not put blocks on the front of any truck. It took my Friends wife 10 years to get his insurance money after he killed himself with 6in. blocks on the front of his truck. It said on the package not to be used on the front of the truck. all manufactures will tell you this. Your insurance company also, and any true offroader will also tell you the same thing. Many 4 wheel groups will not let you near them if you run blocks on the front. Do some proper research and spend a couple of bucks more to to have it done right and to be safe and happy with your truck in the long run.
