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.

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.

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?

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.
