Upgrading stock sagging suspension

Anyone install Dayton/Husky 22-1567HD 4 pack leaves?

Postby MAD MARK [OP] » Feb 22 2021, 5:01pm

I am thinking about installing new rear spring packs come spring time. I did a search on this and many of the topics went unresolved/unfinished.

Anyone ever buy the Dayton 22-1567HD rears? They are 4 leaves but upgrades from the stock 1500 to a 2235# capacity. I would like the extra capacity as I tow (7000#) and haul stone (1800#) often. My stock rears are sagging now at 83,000 miles 2011 GMC 1500.

I was in a similar situation last year with my 2010 sagging around 140,000 miles. Although I did not purchase the HD spring packs. Instead I purchased an add-a-leaf kit from summit racing and upgraded u bolts from 9/16" to 5/8". I installed them with a little help from my dad in the driveway in one day. Total cost was under $200.

The results were good. Immediately the truck sat about 1.5-2.0 inches higher in the rear, but after a while it settled closer to 1.0 inch of rear height gain. This was just what I needed to level the truck with new coil springs in the front also. I believe the truck handles with much better control in the rear now. It did not make the ride harsh at all. Another plus was it reduced the amount of clunking during aggressive starts and stops.

I imagine the HD spring packs would have similar results but for higher cost and more work to remove and replace

I used the McGaughys brand but it looks like the Tuff Country is a better deal for the same thing now

Thanks for the information. I may end up going this route. I just have to check my Ubolts to make sure they are long enough to accept or I have to order new.

I recommend going with new u bolts. They are not meant to be re-used. I got some longer ones linked below. Turns out I did not need longer ones. Being a 2wd, mine did not have the blocks so I ended up cutting the ends off with a hack saw.

My truck was hit in the back end and bent my springs. I took them to a local truck spring company. They straighten them and re-arched them to factory dimensions for $20.

That seems like a good deal. How hard were they to get out? Did you have to drop the fuel tank?

It was not a bad job. I kept the tires on the ground and just lifted the frame up some with my lift.

I used a 4" cut-off wheel to cut the front bolt off and installed the new bolt with the nut on the gas tank side. Like the factory should have.

"They," say you need to replace the U-bolts but I did not. I just checked them a few times to make sure they stayed tight.

Good idea, the labor guide always gives the more complicated way to do things. I don't know what GM was thinking putting the bolt in like that either. The 2500 u-bolts are probably much better than the 9/16" ones from the 1500 trucks. 5/8" bolts fit no problem through the stock bottom bracket so I wanted to upgrade them too.
