Lowering kit help

[Brandon Watson]

Guys I just bought a crown lowering kit 2 4 drop.Spindles in the front and springs in the back. After I put the spindles on the front my tahoe does not look any lower it measures 36 inches on stock 20's. Is there something else I have to do on the front for spindles to work?

Brandon, these torsion bar trucks take a few good bumps and a few minutes of driving to settle down.

take it for a short drive and then report back to us.

What Colby said. You had it unloaded while you were swapping the spindles. Go for a shakedown and be prepared to be astounded. Also, I don't know about the GMT800, but the spindles for the GMT900 actually drop 1.75". At least you can adjust your torsion bars (within certain limits) to make it sit where you want it.

You got a 2/4 drop. Was the rear actually 2" higher before the drop? What where the measurements at each corner before you dropped it?

 

[Brandon Watson]

The back was 38 and 1/2 the front was 36 1/2

The driver side rear is 32 1/2 the front is 34. The passenger side rear is 33 1/2 and the front is 35.

Looks like the rear shocks are shot

How can you tell that from a pic?

That really doesn't look like a 2" squat in the back. Are the tires different sizes? The rears look smaller.

Unless he got 5” drop springs by accident that’s the only other thing that’s going to make the rear end sag .

The driver side rear is 32 1/2 the front is 34. The passenger side rear is 33 1/2 and the front is 35.

The driver side is always lower due to the infamous Chevy Lean. Averaging the left and right, you got 2" of front drop and 5.5" of rear drop. First, adjust your driver side torsion bar to level it, drive around to settle it, then re-measure all four corners. Springs rarely drop exactly they're advertised amount. Yours dropping 1.5" more than advertised is quite excessive. If they ride fine to you, then just get spacers to make it sit where you want it to.

Shocks don't affect ride height unless they're too long or too short for the application and/or mods. Something is screwy with his springs, though.

So I will have to get torsion keys to get the front level with the back?

Could the front jounce stops be too long?

No. Do you want to lower the front more to match the back or raise the back to match the front (since it dropped 1.5" more than it was supposed to)? If you wanted a 2/4 drop, then you should raise the rear since you got your 2" of front drop. It's the rear that dropped way more than planned. You're probably resting on the bump stops and it rides like a wagon. If you like where the rear is, even though it's much more than you bargained for, then you'll have to lower the front.


To lower the front, jack up the front to let the wheels hang, then back out (loosen- righty=tighty, lefty=loosey) the adjuster bolt a little, set the front back on the ground and go for a drive to settle, reassess and adjust more if necessary until the front is down where you want it. If the jounce bumpers (on the frame, just above the control arm) are still present and in good shape, you may need to trim them a little. The control arm should be resting on them, but not squashing them. The amount of drop or lift for each turn of that adjuster bolt varies a little from vehicle to vehicle, but a general rule is 3/4 turn of the bolt equals 1/4" of adjustment. So, to come down an inch, you'll need to back it out three full turns. Remember that the driver side is lower, so you won't need to back it out as much.

His initial drop with spindles wouldn't be affected by the jounce stops. Any adjustment to the adjuster bolts for further drop could/would be.
