Springs showed up within 3 days not 2 weeks as expected. Nicely done! Installation took me about 2 hours. Install was easy. We took the van on a 300 mile road trip the next week. Trip included driving in heavy cross winds (15-25 mph) and one encounter with a dust devil at 70 mph. Winds were noticeable however the handling was always solid. My wife does most of the driving due to her propensity for car sickness. She loves driving the van and was very happy with the springs performance. I would recommend this product to anyone wanting a bit more firmness in ride and handling. Well worth the money especially since DIY is very easy.

It Works. Ride improved. I was skeptical. Cost is Worth it. Noticed softer, but firm cushioned ride immediately.
