Added the Dexter to mine. VERY happy. Good thing I did it too. The factory spring shackles were so worn through, one was only about 1/8" from letting go. With the Dexter, I know longer feel when the trailer goes over rough expansion joints or potholes. Previously, I could feel those almost.
One downside.... You also can't feel a tire blowout anymore.... When mine happened, it was in heavy snow so I didn't know until I stopped for gas. (can't see the tires through heavy blowing snow). Only indication prior to getting gas was losing the trailer brakes. I've had trailer tire blow outs before and felt them every time, up until having these suspension equalizers.
So... if you can swing it, I highly recommend a TPMS at the same time!
