I have to say however, that the IRS would hook anywhere, and I had it working pretty well - yanking the front tires a good three feet or higher. The biggest advantage to a solid axle in my opinion is less maintenence and parts availability. With a 12-bolt IRS the special ring gears are a little more difficult to come by, and are more expensive than a standard 12-bolt gear. I wanted to run a 4.30 gear at one time, and I couldn't find anyone who had one in stock. One final note: My solid axle setup is about 115 lb lighter than my IRS. Just my 2 cents. Good luck

Ben, glad you posted. I had never heard of anyone breaking one until now. what kind of 4 speed and clutch did you have? what were your average 60' times? I agree that the IRS will hook in a car wash, or on a dirt road, etc. As for the rear gears, and good machine shop can turn modify a standard 12 bolt PRO gear
