Lower-capacity electric A-frame jack with a built-in work light and manual emergency crank.
Stromberg Carlson JET Electric Tongue Jacks: Capacity & Parts
Choosing an electric tongue jack starts with the trailer's loaded tongue weight, the mounting opening and the ground clearance needed for hitching. Stromberg Carlson's JET series ranges from 2,500 to 5,000 pounds of rated lifting capacity. Each model uses a 12-volt electric drive with an emergency manual crank, but the housings, lower leg arrangements and replacement parts are not identical.
Check capacity, travel and installation height
Loaded tongue weightChoose a jack with capacity for the actual trailer tongue load and any additional force needed during hitching. A larger jack does not increase the trailer or tow vehicle's rated capacities.
Travel versus drop legAll five JET models have 18 inches of powered vertical travel. Selected higher-capacity versions also include a separate adjustable drop foot, which reduces how far the motor must extend.
Housing and service partsJET-3555 is white and JET-3755 is black, both rated at 3,500 pounds. JET-4500 adds a ball screw. Compare the original MPN before choosing replacement caps, covers or mechanical components.
Measure before ordering: Confirm A-frame mounting clearance, jack-hole diameter, trailer-side bolt pattern, tongue weight and enough height for the jack to retract safely during towing. Disconnect the trailer from its electrical power before working on the jack, and follow the manufacturer installation instructions.
JET model capacity and feature chart
The power stroke is 18 inches for each listed model. Stromberg Carlson's dedicated JET-4500 model page lists a 4½-inch drop leg; the other higher-capacity models shown have a 5-inch drop leg. For a repair, use the exact model's parts breakdown rather than assuming a shared foot or motor.

Frequently asked electric tongue jack questions
Are JET-3555 and JET-3755 the same colour?
No. Both are 3,500-pound electric tongue jacks, but JET-3555 is white and JET-3755 is black. Their illustrated replacement-parts reference covers the shared family and distinguishes individual service components.
What makes JET-4500 different?
It uses Stromberg Carlson's ball-screw drive and is rated at 4,500 pounds. The dedicated model information also lists three LED work lights and a 4½-inch drop leg. Check its exact replacement parts rather than substituting those for another JET model.
Does an 18-inch stroke mean an 18-inch installed jack height?
No. Vertical travel is how far the powered post moves. Retracted height, the foot-leg position and mounting plate clearance are separate dimensions that must be checked on the trailer.
Can a heavier-rated tongue jack increase towing capacity?
No. Its lifting rating applies to the tongue jack. It does not change the trailer's gross rating, the tow vehicle's hitch or payload limits, or the installed mounting structure.
Are manual crank handles included?
Stromberg Carlson's JET product family includes emergency manual-crank operation. Check each product listing and manufacturer packing instructions for the exact supplied handle and hardware.
Follow the manufacturer's current mounting, electrical and service procedures. Use wheel chocks and safe support before raising or lowering a trailer tongue.
