pictures probably won't help too much other than maybe showing before & after ride hieght. Thats becuase they ussually only adjust a 1/4-1/2 turn at a time. All you need to do is measure from the center of the wheel to the edge of the wheel well (before adjusting the bar, while vehicle is not on jacks). Give the nut a 1/4 turn and re-measure. You don't want to add any more than 1" lift with torsions. and be sure each side is adjusted evenly otherwise it will wear REAL bad on the tires. You'll notice the ride stiffen up, and you definately want an alignment check when its all said and done.
I might have some before and after pics of my old 89 S-10. Stock when I got it and then lifted 1 1/4" by cranking the bars and adding longer rear shackles. I also had 31x10.5 Mud kings on the factory alloy wheels.
Give me a chance to dig them up and get 'em scanned.
YEah i got some i'll post the before here and then the after ones on the next post ok. For info. its a 94 S-10 with 225000 miles nice huh. She looks good for her age and miles. I have 31's on it now and its about the ride height of a ZR2. O and i have bigger wheel spacers on it now and fender flares so it looks like one also. Any questions let me know.
