It is possible to mount the springs on top of the axle which is called "flipping the axle". To accomplish this we normally recommend an over-under conversion however there is not one with square u-bolts available for your square axle.…
Hey Randy! The #DE66AR has 1/2" wheel bolts and the #DE68AR has 5/8" wheel bolts. Are you looking for a complete kit with a specific wheel bolt size? What is your axle capacity? The #DE66AR is also for 7k axles and the #DE68AR is for 8k.

The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers #RM-2460-2570 will not include wet bolts. This is due to the system using slipper springs to replace the double eye springs that come on most trailers. With the slipper springs…
Trailer suspension uses different components for the air systems than the frame mounted suspension you are looking at. For your tandem axle Keystone Montana, I recommend the Lippert Components Trailair by Center Point Air-Ride Suspension Upgrade -…
