ok 4 in block question

I could NOT stand when i had my 4in blocks in, I mean its cool but..So much axle wrap.. One day i was racing my buddies' b2200, with my 205 40s, ended up breaking the tires loose at like 100 haha..soo..I dont know about the big blocks so much anymore... lol

mine has 4 inch and all the leafs...for now

Damn you can get your truck up to 100?

I wouldn't go with a 4" block. If you want to go another inch lower, pull the second longest leaf out of the pack. Then when you reinstall the u-bolts, leave the stock bump stop in. For mors axel clearence, you can take a hack saw to the factry bump stop. Cut it about 1/4" above th u-bolts. This will give you a little cushion and stop annoying "frame slapping" sounds.
