I have had the Sulastic springs installed for a while now and I was very pleased with the ride improvement. One way I could descibe it is that the rear suspension is similiar to the front now when going over bumps. It is much smoother as opposed to the harsh jar that was there before. They are made much heavier than the stock shackles also. I would recommend them if you are looking for a smoother more "car-like" ride from your pickup.
Thanks to Nick for a great product.
