Re: 81 K30 Flat Bed
The rear end is back in with new springs, a 1" block from an overload spacer, new seals, new shocks, the Velvet Rides, and the diff cover i got off Allentown CL for $100. I also removed all the unused exhaust hangers that were not riveted. It looks a lot cleaner and it has a nice rake to it now.
I went over the Cascades this weekend and picked up a smooth aluminum Pro Tech 60" in bed box for $350 off of Salem CL. I am going to polish it to mirror finish. I will post before and after pics. Next I need to work on the flatbed metal and lighting.

Re: 81 K30 Flat Bed
What springs did you get for the rear? I've seen several different weight ratings for these trucks and those look like a lot of leafs.

Re: 81 K30 Flat Bed
Thanks guys again.
Here is the new stance. It used to be slightly lower with no load in the rear. I read that the Velvet Rides could lower the ride hight some which is why I put the extra 1" block in there. There is a huge difference in ride quality compared to the few miles that I drove around on all the worn out hdw that I replaced. I am very happy with it and cant wait to get a few cords of wood in it. Marcus, the rear springs are 8 over 1. I called Oregon Spring to get mine rebuilt and rearched and they said it would be cheaper to get new rather than rebuild because of freight and the fact that I live in the middle of nowhere. It was 8 over 1 or 9 over 1 which is the heavier gvw for these trucks. I said great give me the p/ns and I will call back after counting the leaves. So I took the p/ns and hit the internet and found the cheapest to my door. They are Dayton/Stanley springs. Joe, its the Aluminum tool box that is going to get polished and the bed painted. I wish it was the other way around. y5, those Velvet Rides have been sitting in my garage for 9 years and 11 months according to the receipt. I heard they were sold to another mfg and then fizzled. I wish my air bags would fit this c&c layout but there is no room between the brake backing plate and the leaf.

Re: 81 K30 Flat Bed
Do those overload spacers you used for blocks have center pins or just a open hole in the center?

Re: 81 K30 Flat Bed
Center pin. Its a 1" overload spacer then the 8 over 1, then an overload spacer doing what its supposed to do with the overload on top of it and the center pin through them all.

Re: 81 K30 Flat Bed
The bare spacer just has a hole through the center.

Re: 81 K30 Flat Bed
Working on the bed.
Restoring the clearance light bodies that are getting new lenses. I was given a free set of used mud flaps and I am sizing them for spring clearance at different loads and final length. Oregon requires 27" from surface and my other home, Texas requires 8". I plan on some fancy artwork on the new set after I figure the final fit and use the used ones as a pattern. Removing a primer surfacer and three coats of black paint. I have about 1/4 done.

Re: 81 K30 Flat Bed
I am still working on the bed as time allows, stripping the doner truck, and I have been pulling my hair out over a no up shift except via the goverener which turned out to be my downshift solenoid fell apart and was hanging by its wire.
It shifts great now and it even downshifts. Man I love this truck.

Re: 81 K30 Flat Bed
Did the Velvet rides change your ride height any? Was there a big difference in how it rode after the install. I had never seen these before.

Re: 81 K30 Flat Bed
I can't say if the ride height was changed because I installed brand new spring packs and an extra overload spacer at the same time.
I did not drive it long enough before the installation to tell you how big of an improvement they are. After X amount of weight is put on the bed the knee action locks out and it becomes a solid shackle. Because this truck will actually be used to carry weight and I did not want it to be nose high when loaded I put in the spacer and new springs. As I said before, I sure wish my air bags would fit. I can tell you one thing though. It rides great with about 750 lbs back there.

Re: 81 K30 Flat Bed
Did any of these cab and chassis trucks come with a rear sway bar?
Would a CnC sway bar be the same as a 3/4 or 1 ton rear sway bar?

Re: 81 K30 Flat Bed
Picked up a Reunel winch bumper off of C/L today. It will probably go on in place of the chrome Warn. $200.00

Re: 81 K30 Flat Bed
MTCK.
With 2 scales underneath I came up with 220 lbs with no winch. Today I finally installed the electric choke on the 4160 and adjusted the floats and idle mixture. The TH400 kickdown does not work. That is next on the list. I need to get 84+ grill and lights so I can put the bumper on.
