Lift Question

[Jslat6]

Do they make a lift kit for an 80 standard cab 720?

[datzenmike]

Body or suspension, or both.

[Jslat6]

Sorry maybe I should have been more clear. I am looking for a suspension lift between 3 to 6 inches.

[datzenmike]

After '83,5 the 720 fronts changed, too bad. I believe you could get drop spindles for the D-21 that would swap to those years. The backs are easy, cut the spring perch off the rear axle and weld on top, mount springs above the axle, or get an '80-'83.5 4X4 rear end already done this way with shock mounts.

Is it a 4x4?

 

You can:

 

Crank the torsion bars up if it's 2x4 or 4x4....

 

Solid axle swap if you want 4 wheel drive.

 

Toyota or Jeep Wagoneer axle would be the easiest.

 

Do you plan to wheel it or just drive it?

Says hardbody, but at this point your fabbing anyways.

Actually it is going to be a lease truck. That is the reason for the lift and flat bed change.

Lease truck?

[datzenmike]

Maybe a modest body lift, new shocks and an extra main leaf per side if it's for carrying loads. You don't want to raise the center of gravity if carrying a load. Stiffer springs will help prevent any bottoming out.

Here in Bakersfield it's a vehicle used in the oil patch.

ahhhh. Why lift it then?

It is going to be on our Deer lease. being used to get us around the mountains and to and from the camp house. Lots of hills and dirt. We picked up this 1980 standard cab model 720 and figured why not put a flat bed on it cause the truck bed is rusted out. And put a small lift on it for larger tires and going through mud and over rock to pick up the dead game.

In that case, I'd say put the biggest mud tires you can fit without lifting it. Keep the CG down. If you need a bit of lift crank the torsions up front and blocks for the rear.

Get 29", 30 tops without a 3" body lift on a 720. Even with a lift 31.5"s will rob off road lugging torque specially on a 2wd without transfer case. As for width, narrow with extreme tread pattern, will bite down through soft surfaces better, provide lift, are lighter/ cheaper. Wider will spread the weight over a larger surface area and are cooler looking.

 

As for the wheel diameter affecting your over all gearing it would depend on what you have now. If you have reg cab short wheel base manual tranny, then you also have a power robbing 3.889 rear ratio. If you have reg cab long bed manual tranny you have a 4.11. If you go to larger tires you could swap the rear gears from a reg cab short wheelbase or KC automatic or a long box automatic truck that have 4.375s in them. Much better for in the bush.

 

If you aren't sure what truck has what gears, Nissan was nice enough to tell you on your truck. Look on the inner passesger side fender just below the hood hinge. There is an aluminum tag, and near the bottom it will say something like:

 

TRANS/AXLE..... FS5W71B...... HF43

 

The 43 means 4.375, 41 would be 4.11 and so on.. It could also say HF37, HF39.
