The shop sold and installed bigger sway bars front and rear, track bar on the rear axle, and Koni shocks on the rear axle (Koni's for the front axle are on back order). They also did a full, four wheel weight, and alignment. This work was done on my 2005 Class C, Ford E-450 base vehicle. Results confirmed my long held suspicion that the coach was not really set up at Winnebago when it was built. The drive home (397 miles thru the Siskiyou and Sierra mountains, confirmed that the work done was well worth while, as the previous unpleasant tail wagging, wandering and lack of proper tracking, were no longer evident. All the personnel were pleasant, efficient, and knowledgeable. I can definitely recommend Henderson's.
