I spoke with my contact at Lippert regarding your existing motor/gearbox model 5973820. He stated that the correct replacement motor is the Lippert Components Kwikee Step Motor Replacement Kit #LC379608. This is a direct replacement for the motor…

The Extreme Off-Road Ratcheting Trailer Jack part #ORJW1SU has a 770 lb weight capacity which means so long as the tongue weight of the trailer does not exceed this then you'd be fine. A trailer with GVWR of 4,000 lbs would be no worry at all.

When fully retracted, or collapsed the jack is 28.58 inches tall, and 38.42 inches tall when extended as shown in the provided diagram. I've linked you to a product description video featuring the #ORJW1SU ARK Extreme Off-Road Ratcheting Trailer…

The Extreme Off-Road Ratcheting Trailer Jack #ARK54FR is going to be our tallest side wind pivoting jack that will mount the side of the boat trailer frame. This jack will extend to 32-1/4" from the center of the mounting point on the jack to…

The long brackets of the Removable Extreme Off-Road Swing-Up Trailer Jack #ARK57FR that mount on inside of trailer frame are little misleading since they are much taller than the bracket on the other side of the jack that it attaches to. Basically…

I checked your order notes and the leaf springs you bought last year were the part #e28SR which are for 5k axles. Since this is over the capacity of your axle failure would not have been caused by over loading the trailer assuming you stayed under…

Regardless of the amount of leaves a leaf spring has if the capacity is the same between two of them they would both flex and bottom out the same. I would recommend you have your trailer and boat weighed so that you know whether or not you are…
