If I didn't already own a set of Slide a links that's what I would have bought and used.

More adjustable.

Also, the guys who were bending springs went to these to stop the bending. I'm nowhere near fast enough to bend a spring, but if you don't have a set of bars, this is what I'd buy.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
