For upgraded shackles on your 2020 Heartland Cyclone 4007 5th wheel I recommend one of our suspension upgrade kits. In order to select the correct kit you will need to know the length of your current shackles. If you have 2-1/4" shackle straps…

The MORryde Suspension Upgrade Kit #MR26ZR is designed to be used with the MORryde Rubber Equalizers for Triple Axle Trailers #MR39ZR. This equalizer kit only requires 6 sets of shackles as it removes one set of the shackles and allows the leaf…
