Next job - lose the sag

[mechagouki]

So, i have typical rear end sag, and the truck is kind of bouncy in back, I know new shocks will fix that, but for the sag I`m hearing re-arch and add-a-leaf is the way to go. how much, ballpark, should I be looking to pay to have this done. Also, the truck came with some new 2" longer shackles, is fitting them a good idea

thanks.

I fixed our sag on a 1990 4runner by rebuilding the suspension, ie:
-new coil springs and shocks
-re-bushed entire suspension(rear, lateral, a-frames-upper and lower, etc)
-new torsion bars
-factory re-align
-ball joints
I found after doing the rear suspension completely, it looked somewhat unbalanced. The front was just plain tired after so many years. The bushings were allowing the torsion bar to distort the suspension level. This was also happening in the rear. The sum of the parts, expense wise, was not terrible. It is the amount of labor that gets you. If you can DIY, it is a no-brainer in improved performance and handling.

For your 89 try an add a leaf. That should take care of it

AAls are great for quick fixes. They will pick the back of your truck up, but will make the ride a little harsher, IIRC they cost about 50 for a set and can be put on in an afternoon.

You mentioned having longer shackles. They will pick it up about an inch, and since you already have them, I say put em on.

The REAL way to fix it, is to replace the springs or have them re-arched.

Best fix would def be new spring packs.
AAL will lift but harsh the ride.
Re-arched springs typically don't retain it too long.

So AAL harshens things up, but am I right in thinking that longer shackles will soften things, so if I do both i`ll gain a little lift without comprimising the ride too much?

or you could get the front coil springs off a late 90's jeep cherekee and stick those in between the bump stops. takes away the saggy, gives you more overload, and honestly doesnt give you a bad ride at all!

i got mine at a scrap yard for 20 bucks. if you do it make sure you cut off 2 inches of the coils on each. that seemed to be just about perfect. just my 2 cents......

The longer shackles will simply lift the vehicle that much higher off the springs, so it won't directly influence the springs' effects on ride quality.

However, this change in height will change how the shocks act and I'm pretty sure I'm not capable of describing how.

I have the opposite issue, as the PO put in 63" Chevy springs with 6" shackles and matched (I think) shocks. I wanted to eliminate some of the stinkbug look I had (rear end too high) and drilled new holes at the 3" point in the schackles, thus lowering the rear of the truck about 1.5". But that started causing the shocks to bottom out and created a really harsh ride.

So I guess the long answer is you need to take all things (springs, shocks, shackles) into consideration.

Wait, what? Surely you're not suggesting the OP actually tune his suspension, are you?

Cuz I'm pretty sure we don't do that sort of thing here.
