Last week I decided to order an add-a-leaf kit from Tuff Country. They came in yesterday so I went to work.
last time I was under the truck I noticed that my leaf springs where strating to bend to opposite way. Or at least ride flat. And with the small pop up trailer I have, it was best to add some spring back into her. Let me tell you that doing this job without any power tools is not the easiest at all... Here are some before, during, and after pictures... I'm very pleased with this product and would definitely recommend them. The set was 172 Canadian after shipping and taxes. They came from salt lake City to my front steps in Ontario within three days.

I will post some before and after pictures of the side of the truck after work today hopefully, and just an idea of what kind of tools I used, the last pictures is the setup I did in order to remove the bolts on the u bolts holding the axle lol.

Oh and the during pictures will be posted as well

 

Here are the before and after pictures I got... Really ridding nice smooth and level now. Just need to get a better setup for the front so I can stop changing the ball joints every year. Looking into some super lift front upper control arms, they are angled for a 1.5" lift and with the tube fabrication it gives it a better look front teeth flimsy stamp one that's there.

 

I had add-a-leaf in my 4 door Blazer. It made a huge difference in stiffening up the suspension, and I really liked it.
