Keep in mind I was comparing stock suspension to the alterK. Now 100% of what I said is true.
I'm personally very happy with the AlterKation. I agree stock suspension can be upgraded, to get the job done, or even do it better. In regards to looks, why do people paint or powdercoat suspension parts?
Now here is the part that gets me...we are here talking about QA1 setups and other aftermarket parts. Some of these setups, while retaining the torsion bars, replaces every part of the stock system. Some guys go one step further and replace the stock steering box too.
Another thing I despised about the stock setup was the early style biscuit mounts. They left alot to be desired, especially after hacking the drivers side mount for the schumacher conversion mounts. YEs, you can make your own DC K-member or get yourself a 73 and newer K-member. Maybe i'm just lazy but parts are harder to find and my time is valuable, so again, for me, I like the alterKtion.
If you are going this far, I preffer the ALterKtion. THat is my opinion based on my experience.
