Recently we were referred to Wodonga Spring Works because of problems we were having with our Jayco Optimum Motorhome where the ride was poor and we had some difficulty keeping it on the road. After assessment by Chris (owner) he recommended that we replace the springs, somewhat reluctant, as I was told that we already had "heavy duty" springs, I agreed. The decision proved to be the right one, as the ride is now so much better, it is like driving a different vehicle. Well done Chris and Shaun, much appreciated !!! Highly recommend these guys. Colin H
