Arrived as expected. The instructions that come with it are good and clear. Installation on my 2010 Winnabego VIA (Sprinter 3500 chassis) was easy but took a little longer than expected, mainly to boot the car up safely. Reduced sway and severe sway when turning and turning off the roadway. Noticed an improvement in handling at high speeds. At the same time, a Hellwig stabilizer was installed. The combination led to a significant improvement. Very satisfied, although we still feel bumps on the road!
