How is the stabilizer attached to the frame: welding or bolts?

It comes with 4 bolts which are used to attach to the trailer frame. This assumes your current stabilizer is bolted on or you are able to drill holes.

Are the arms able to be lowered at different levels? Example would be a trailer leveled with tire blocks so one side is higher than the other.

the lippert unit is self leveling. Both legs travel down at the same rate, when one touches ground it stops until the other side hits ground, then the both continue to stabilize. I have both the lippert unit and the ultra fab power twin unit. I will be replacing the remaining lippert with another ultra fab this year as the lippert doesn't stabilize nearly as well as the ultra fab.

Will these fit on a 36 foot fifth wheel big country? we had a set and froze up so can i just put them in the same spot as the old set?

That is a good question. I installed this on a 40 ft Sabre. it is not a wide body. I do not believe yours is either so it should fit.

what weight rating are these stabilizer jacks

Stabilizer jacks do have weight rating but don't know what these are rated at.
