Has anyone been running these and if so, how did you like them?
Some are rated at 1,000, 1,500, and 6,000lbs. Some have an air gap of 1/2" and some at 2". The air gap should keep the stock ride feel. But which version have you tried? Do they help on body sway? Do they feel like a rock when the payload meets the bump stop?
Do the smaller spring ratings do much to the ride when a hitch is loaded? Are they a smooth transition when going over bumps, bridges, or etc.?
Give it up and tell your experiences when pulling a trailer front or rear applications.

Note: I know they say do not go over the stock Tow rating. This is just a question as to how they affect the ride.

Thanks!
