R&P Service Insight
Trailer jack fitment depends on more than the load rating. Before replacing a jack, confirm the mounting style, bracket height, crank clearance, and available swing-away room on the trailer frame.
- Capacity Check: This jack is rated for 8,000 lb static / support capacity and 5,000 lb lifting capacity.
- Mount Check: Designed around a pipe mount swivel setup with included mating mount, pin, and chain.
- Clearance Check: Verify 17.10" retracted bracket-to-bottom height, 27.10" extended height, and 7.30" bracket-to-top clearance against the trailer before ordering.
R&P Knowledge Hub
Compatibility: Compatible with trailer applications requiring a Pro Series square pipe mount swivel jack with 10" lift, sidewind manual crank operation, fixed leg, and footplate. Verify before ordering.
Vehicle / System Fit: Commonly used on utility trailers, equipment trailers, agricultural trailers, cargo trailers, and other trailer frames set up for a tubular pipe mount swivel jack.
Installation Notes: Confirm the jack can rotate without contacting the trailer frame, coupler, toolboxes, battery boxes, spare tire mounts, or other accessories. Mount installation should be performed with proper alignment and secure attachment.
Performance Insight: The 12-gauge square tube design provides added side-load and support strength versus similar-capacity round tube jacks while maintaining the same rated lifting capacity.
Brand & Fitment Note
Selling Brand: Pro Series
Application Reference: Trailer type references are general fitment guidance only. Final compatibility depends on mount style, capacity requirements, clearance, frame layout, and installation position.
What This Means: This listing is for a Pro Series square pipe mount swivel trailer jack, part number 1400860383, not a guaranteed factory-installed replacement for every trailer.
Before Ordering: Verify jack capacity, pipe mount style, outer tube clearance, bracket-to-bottom measurements, bracket-to-top clearance, crank access, and included components before installation.
R&P Repair Insight
When replacing a trailer jack, match the old jack by function and geometry, not just by advertised capacity. A jack that is too tall, too short, or mounted in the wrong orientation may interfere with towing, turning, or storage.
- Measure Bracket Height: Compare the 17.10" retracted and 27.10" extended bracket-to-bottom measurements to the trailer’s current setup.
- Check Swing Path: Confirm the jack has room to swivel up and lock in place without contacting the trailer body or nearby accessories.
- Confirm Tongue Load: Select the jack based on the actual trailer tongue load and lifting requirement, not total trailer GVWR alone.
