simple mod to do, I did it myself.

1. Loosen lock nut on each side
2.Measure where your frame is now on each side towards the front
3. 19mm to crank the torsion bars making sure the lower nut does not spin. Takes more than 4 turns....but just crank them and keep measuring the frame on each side.
4 they say you can go anywhere from 1"-1.5".
5 Make sure you have atleast 1/4" room left above the upper bump stop.Both sides level with eachother.
6 Tighten the lock nut on each side.
7 Go get an alignment done. Check them in a week or two, they will settle and need another crank on them.
