I’m looking at getting a leveling kit on my truck. The rear blocks are 3 inches high. Are is there anything I can put in the front to make it even with the rear

 

The typical leveling kits are either 2" or 2 1/2". Instead of looking at what size block you have in the rear, measure your truck bumpers height off the ground and compare front and rear. If you can find a level place to park, measure the front bumper height currently, then stick a jack under the frame and jack it up until you like the way it looks. Then measure again.

Depending on how picky you are, and since these trucks aren't exactly new and might have some worn springs and such, either find a leveling kit that will work based on your measurements, or find a local spring shop and have them build you new front springs that will produce the desired lift.
