I have a 2006 4x2 with a 2.5 inch leveling kit installed. Tires are currently 285-70-17. The back is sagging by about 1-0.75 inches. Found a local guy selling his 4x4 blocks. I'm almost positive I can just slide them into my truck to get that tiny bit of lift needed to level the truck out (or give it a slight rake).

I'm thinking i'll need his U-bolts as well....

Will this work?

Thanks!

 

Yes you can and you will need the U bolts.

 

That is what I thought. Appreciate the response.

 

Did that on my 4x2. Very easy job. Just re-torque the U bolt nuts a couple times after.

All you need to do is lift the truck by the leaf springs one side at a time. Take off the old U bolts first. They do slide right in. You might have to shake the each wheel around a little to get the pins to fall into place. Use jack stands. Check my gallery for pics. I did not lift the front, just wanted extra rake.

Do you want it more level or raked? If level, go with the oem blocks, if raked, go with 3" blocks.

Thanks for the replys. I installed them this weekend, wasnt too bad. I ended up using a piece of a 2x4 and a mallet to knock the block in so that the pins and holes lined up. I jacked up the truck from the frame and let it sit on jackstands which just let the suspension hang down. Then I used the jack to support the axle and lift and drop it when needed. It sounds like I took the harder path.

When you added your blocks did you change your shocks to a 4x4 length shock? I did because I felt that the 2wd shocks were going to be too short...

Overall my truck has a very slight rake, maybe half an inch. But it looks way better than when it was sloping towards the back (bulldog?)

 

2WD shocks will work, but they will bottom out if you get up in the air a little. You'll just hear a slight klunk. But if you drive like grandma, you could probably wait until you need to replace shocks and get 4WD length shocks.

 

I did not change the shocks..
I put my 4x4 blocks on in June. It's now December and I've never had an issue with the shocks bottoming out. I've never felt our heard anything weird from the back.

What did you torque the nuts on the new U-bolts to? I first torqued them to 80 lb/ft and re torqued a few times. Finally ended up leaving them at 90 lb/ft and they haven't budged. In that time I've also towed a 3000# trailer about 1600 miles. No issues.

 

Reusing U-bolts is never a good Idea. Nothing should happen, just throwing that out there.

 

I replaced the shocks with 4x4 length ones. The OE shocks that I pulled were totally shot. I don't recall to what torque i tightened them back up, I used the Pro Comp 3 inch block installation guide and I torqued to whatever was listed in there.
