I am just getting ready to replace my 3 yr old Bilstein shocks on my 07 32 ft Jayco greyhawk with 5500 Kodiak chassis, with Koni, the reason is the rebound with the Bilstein if horrible, sways like a drunken sailor, and yes I have new sway bars front and rear, also track bar.......... So going to give the Koni a try..........
