The Stromberg Carlson JET-5000 is a 12V electric A-frame tongue jack rated to lift up to 5,000 lb. Its switch, work light, level cap, foot and manual crank can be identified in the manufacturer's numbered exploded drawing. Match the original jack model and part number before ordering a replacement.
The Stromberg Carlson installation manual includes the A1–P numbered diagram on page 2, along with the original part numbers and instructions for mounting, wiring, operating and maintaining the jack.
Replacement for a complete jack with 18 inches of vertical travel, LED work lights, built-in level and a manual crank-through-head feature. The foot, safety pin and crank are included with a complete factory jack.
Power switch: check the extend/retract rocker and its protective boot. Missing foot: identify the round pad and separate 3/8-inch pin. Damaged level: the screw-on cap and bubble level are different service items. Match the complete part number rather than a similar-looking head cover.
Use the callout letters below with the exploded drawing. The manufacturer assigns some replacement components individual part numbers; others are shown as parts of the upper or lower assembly. A matching number is required before choosing a separately sold component.

2500-3755G identifies the JET-5000 removable foot pad, while 2500-26 is the separate 3/8-inch retaining pin. 2500-3755E is the screw-on top cap with built-in level, whereas 2500-01 is the bubble-level insert alone. The manual override handle is 2500-24. Check the original part and its mounting dimensions before ordering.
If the motor does not respond, inspect the 12V supply, 30-amp fuse (2500-3755K), self-resetting breaker and ground through the jack mounting plate. The factory instructions require clean metal-to-metal contact at the star washers, and the wire fuse holder should be installed close to the positive battery terminal. Never work beneath an unsupported trailer tongue.
Disconnect jack power before using the crank. Remove the top and side access caps, engage the crank through the head and turn it to raise or lower the jack as instructed. The JET-5000 manual override does not describe the separate brake-release-handle procedure used by the ball-screw JET-4500. Clean and lightly lubricate the telescoping inner jack tube periodically; retract the jack fully before travel.
