i have a 2001 ford explorer with 35 inch tires and the back sags a little more in the front. how could i raise the rear up just a little bit and where do i need to go to purchase the item?

 

I'd suggest a taller lift block or an add-a-leaf. Both are available at 4Wheel Parts, ORU, etc.

 

if you allready have aftermarket blocks,just get a taller block.i just got some bds add-a-leaf's and they raised my truck about 2''.i like havin my stock blocks so i have the bump stop.it rides a little rougher but its not bad.just make sure you get forged blocks if you go that route
