Universal Traction Bars install on a Duster....

These are the best Lakewood bars for mopars . There are bars for the look and bars for the traction. These are for traction. And fully adjustable.

Agree, those are much better, cost a bit more too.

These are for looks in my opinion. All they do is eliminate the spring flex. No adjustment for uneven spring count or arch. Reasonably priced for the look for a low HP car on the street/strip

Disagree somewhat - As I stated in the video, these are the generic version, but still apply the same principle. When your whole back end rises about 2", that's a lot of pressure being applied to the rear tires. Ask yourself, "how much would I have to lift above the rear axle to raise the car up 2 inches?". About 200 lbs or more of pressure, meaning that's about how much is being applied to the rear tires. again, the generic form, but still do more than just "looks".
