56" rear spring swap?

[Bob87Burb]

I did a search, and didn't find the info I needed. Perhaps I missed it, sorry if this is a repeat (or threepeat).

My 87 1/2 ton has 52 " rear springs (rough country, they suck), and I can get a set of 56" 3/4 ton rears fairly inexpensively. I figure that, along with my ORD zero rate, ought to enable me to actually load the truck, and keep it level with the front 2" springs.

From what I've read, the center pin hole in the 56's is offset, so the front hanger stays in the original position, and the rear one is moved. Correct?

Also, what's involved to moving the rear hangers? Are the holes already in the frame for them, or would I have to drill them? Anyone tried this?

Thanks in advance,

Bob

Yes the pin is different from the 52's and 56's. As far as putting in 56's in place of 52's, some rigs already have the holes there in the frame, some don't. If they aren't already there, you'll have to drill them.

You should already havve the holes in the frame since a lot of burbs came with factory 56s like mine

Good news, I checked out the truck tonight, and the holes are indeed already there.

Got a good deal on 3/4 ton 7 leaf springs, so I'll be installing those along with my zero rates I have on the truck now. Hopefully, that'll make it level with the front. I'm pretty sure it will, since the 3/4's seem to sit higher than the 1/2's anyhow.

Thanks for the help guys.
