Ride after torsion bar crank

[Bmp1]

I read about cranking torsion bars for lift. Can you tell much difference in the ride after doing that? I would think it would be considerable stiffer.

Just did it. Raised about 3/4". Doesn't feel any particularly different at all. I think there are different views as to whether that move changes the spring rate. I think likely not or just modestly at full compression. The spring will be more wound up at the compression bump stops. But it's nothing I've noticed. Use the search function for some how to's on that job.

At 2", you bet. Feels super stiff, unless at speed off road. :smiley_drive:

Just make sure not to load the torsion bat against the upper control arm bumpstops, it will ride really bad.

I solved this issue by using OME torsion bars, totally worth the investment.

Do you have a part number? I'm looking for Gen 2.5.

OME303011 ?

2" is a lot.

Cranking the torsion bars does not change the spring rate, it only changes the ride height. As Toasty said - things get really messed up if you hit the bump stops which a 2" raise is likely to do.

As a note - cranking the torsion bars also changes the suspension travel in the up direction (IIRC the geometry).

Be sure to get the vehicle to an alignment shop after the adjustment as you may experiance pre-mature tire wear without a proper alignment.
