If memory serves me correct quad shocks are used on the IRS. They hook to the upper single arm to limit wheel hop induced buy the deflection of the lower A arm bushings as applied torque accelerates the car. This is a weak spot in the IRS set up and much discussion has taken place about how to eliminate it.
Now I am confused (which is normal, just ask my wife). How are the quad shocks connected on the 4 link? I thought the 4 link provided an upper and lower arm om each side to prevent axle rotation? Like to see a picture of this if someone can provide one it would be a learning experience for me.
Thanks for the picture, looks like it does the same thing as regards wheel hop as the IRS set up. I guess I was thinking about a drag car 4-link which has a solid link above and below the axle centerline located at the same point on the outside of the axle. With the quad shock as shown above I quess you could call this a six link set up.
