To my knowledge, there is no height difference. The major difference is in the better shocks, and the fact the coils are progressive. As for load, it'll be the same as the overall weight limit should be similar.

For the price, that would be a killer deal. Again, that's assuming you're replacing your older stock suspension coils and shocks. If you're looking for a lift, you'll need to look elsewhere.
