Questions regarding a 1.5in shackle lift on my 84 4wd p/u
Hey everyone I have a 84 Toyota Pickup 4wd 5spd diesel and I am planning on adding a 1.5 in shackle lift only in the rear. As with most Toyotas the rear end sags and it doesnt help having 31" tires all around on a stock suspension either. Anyways I chose this route for ease of installation and just to prevent my tires from damaging the wheel well.
My questions are:
Other then the install, what else do I need?
ie longer shocks etc.
Could this possibly damage my driveshaft or anything else?
I dont plan on doing much off roading with this truck. It is more of my daily driver and hauler when I need it.
Any answers/advice is greatly appreciated!

You are only going to see about 1" of lift, so shocks are fine and driveshaft is fine. Your good. I would look at getting new shocks and maybe an add-a-leaf to bring the ass end up a bit. With just shackles you still have a warn out suspension, just propping it up a bit, like a crutch.

in general, you'll only see about 1/2 of the extra shackle length added to your lift. So a 1.5" longer than stock shackle adds about 3/4" of lift if the shackle is at 45 degrees.
if you're looking to compensate for a sagging rear, my first suggestion is replacing the springs. Add-a-leafs would be my next suggestion... then extending the rear shackles would be the last option.

You may need to shim the rear axle to correct the pinion angle change caused by the longer shackles:

So you guys are saying that the claimed 1.5" lift is actually going to be 1/2"? What a bunch of crap. Who the hell would waste their money for 1/2"? If I knew this I would never have bought them...

So if the shackles are 5" c-c, then you'll see about 3/4" lift, if they are ~6.5" (3" over stock) then you'll see about 1.5" lift.

Ok, so I got the shackles yesterday and they are 3" longer then stock from center of pin to center of pin. I think I am definitely going to need them for a roadtrip I am starting on soon. I will have a few people in my truck as well as over 500lb in the bed. Seeing as how it will be a long roadtrip (CO-NY and back) I dont want to run into any problems with my truck. Since it is 3" longer then stock I will probably need shims. Where can I get these and what size should I get? Could I put off getting longer shocks for a bit?

General rule of thumb is 1 degree per extra inch of shackle length:

Or best to measure the angle change before and after installing the shackles (simple tape measure technique works fine):

And typically 4.75" long and either 2" wide or if you prefer 2-3/8" wide on the shim size:
