I had Mor-Ryde replace the suspension on our 2005 Holiday Rambler. While doing the replacement I had another 1 1/2" added to the axle spacing and 2" lift to the trailer. I have the Kodiak Disc brakes and have not had a problem. I also installed Blu-Dot air over hydraulic actuation. In my opinion this is by far the best upgrade to our trailer

ps. there are more Mor-Ryde upgrades an opinions on this forum than the 5th wheel forum
