1989 v1500 Suburban

Well I’ve got a busted leaf and a leaky pinion seal. I guess that’s all I need to justify a 14 bolt sf swap. Hopefully going to pick the axle up Monday. I’ve got a 4.10 10 bolt for the front in my parts hoard I’ll just have to swap my hubs onto it.

Got the new axle in the shop tonight and burned in some new spring perches at the correct width. I also verified it was a 4.10 ratio. The brakes are toast so I ordered a disc brake conversion for it. Hopefully next weekend I can get it installed.

After going back and forth I ordered a tuff country ez ride 2” lift kit. All of the springs are kind of sacked out on this, and I have always wanted to try a tuff country kit. Hopefully I like it all aftermarket leaf springs have been less than impressive to me in the past.
 
2” will look good on this thing.
I think/ hope so too. I was going to scab a used single leaf in the broken pack, then throw zero rates on all 4 corners. After measuring each wheel well on level ground I’m a minimum of 1” difference at each wheel, so I’m hoping the springs beef it up a bit and level it out.

The disc brake conversion did not properly fit on this axle. Apparently by “all 6 lug 14 bolt” they actually meant 88’-98’ only. I made them work with some crude 1/4” spacers and some of my booger welds.

Got the axle, springs, and shackle hangers removed last night. Of course everything fought me and all spring hardware needed to be cut. I have to move the shackle hangers forward my new springs are 52” and the factory springs are 56”. Hopefully tonight I’ll get everything bolted in.

It has slight rake with the 2” shackle in the rear, but it’s tolerable until I get the time/ motivation to swap the front. It’s way better than the sacked out broken rear springs. Once I get the front swapped I will most likely go to a factory shackle in the rear again. I also ordered grease-able spring/ shackle bolts from ORD. I’m undecided on which shocks I want to go with; I’m very happy with the KYBs I put on my blazer. I’ve also thought about going with a set of Bilsteins, but I’m not sure I want to spend that kind of money.
