I use overload coils from the local auto parts store on my 244 and 245. The ride is good and they hold up mell when hauling or trailering. They cost more than used, but they're new and last longer. Consider the age and mileage of used springs and price new after-market before you decide. With original used wagon springs and my trailer hooked up, I was nearly dragging the mudflaps, and the headlights lit up the trees. With the over-load coils, same trailer, nearly level and the lights stayed on the road.
