How often to replace bars in rear.

Also how do most people install them. Torsion arm on number side or stop on number side.

I know it doesnt really matter what way they are installed as long as you put it back in the same way you took it out and dont spring it the opposit way it was turned before.

I was just curious what way most people installed them.

Derek - We install the bars with the number side of the bar to the left side of the car. It is just something we do to remember which way the bar goes in the car.

Derek, there are guys out there that will test the bars for you. not all new bars are equal. also if you establish a base # with the bar, periodic testing will tell you if and how much the bar has fatiqued.
