We noticed our camper would level up fine using the HWH leveling system, but it would lean to the left when driving down the road. Turns out the immediate response air valve had lost it's sense of urgency.

In this video we show you how to replace the Haldex Immediate Response Leveling Air Valve on a 2001 Country Coach Intrigue.

Kit # - KN27000
Valve # - 90555105 (This is the new part number that supersedes the old one)

The same kit can be used on the right or left side.
