Ideas for what everyone is using for traction devices?

Looking for ideas as to what to go to for traction device. I am using a pinion snubber now and it kinda works. I am noticing that the snubber is bending in the floor some, even after I added a plate. The plate I used is 10 gauge, but it seems it is not enough strength there.
I am looking at the ones that go on the spring, my springs are Firm Feel +1 HD.
