The Stromberg Carlson JET-3555 and JET-3755 are 3,500 lb electric A-frame trailer tongue jacks. They use the same manufacturer service drawing, but the JET-3555 has a white head and the JET-3755 has a black head. Use the callout letters below to identify the switch, light, foot, crank and other service components before ordering.

Finding the correct replacement
Look for the JET model label on the jack and match the letter in the original exploded drawing. A part number is not a guarantee that a component from a different-capacity jack will fit. If the component you need is not shown as a linked product here, use its exact manufacturer part number when asking us about availability.
