i was given a 2'' lift blocks for the front of my truck to clear my new 35's i was wondering what size U-bolts i should use so they fit right, the originals are too short. oh and the new 35's are nitto terra grapplers almost brand new got em for free

 

Lift blocks on the front are a big no-no, actually explicitly illegal in some states.

Don't do it.

 

its only temprorary until i can afford an actual lift kit so i can clear the 35's due to low funds and the truck needs tires.

 

I agree with Ace. ( first time for everything ) Its a death trap with lift blocks in front.
