Energy Upper Bumps ***UPDATE***

I have been using the 2 1/2" ones with a little improvement over stock, they work OK. They just mash down and give me little sooner overload engagement. http://www.summitracing.com/parts/ens-9-9109g/overview/

So I ordered the 4 1/2" ones to see if they engage a little sooner, but they just spread out and don't do much, fail.

Stable loads? I don't know, getting expensive. Maybe just stick with the 2.5" ones?

    Mine barely make contact but it you need them not to compress much, I think you need solid ones like the stabileloads.

    I have the 2 1/2" ones and I filled the opening/voids in mine with some polyurethane caulking. Took a couple weeks to dry through to the center, but they work great. You could probably use some 2 part epoxy that would cure much quicker. They work much better when they dont compress.
