Overview
This fold-down telescoping stabilizer jack is commonly used on the rear of cargo trailers, motorcycle trailers, campers, and RVs to help support and stabilize the trailer while parked. It is designed for light-duty trailer stabilizing applications and helps reduce trailer tipping when entering an unhooked trailer. It can also be used as a tongue jack stand where the mounting location, capacity, and clearance are appropriate.
R&P Service Insight
Before installing a fold-down stabilizer jack, match the jack measurements to the trailer frame and confirm that the jack has room to move through its full range of travel.
- Mounting Surface: Confirm that the trailer frame or tongue location can accept a 2" wide x 4" long mounting base.
- Hole Spacing: If bolting the jack on, confirm the two 3/8" holes spaced 3" center-to-center match your mounting plan.
- Clearance: Make sure the jack can fold down, telescope, retract, and store forward without contacting the trailer body, wiring, axle, suspension, or ground.
R&P Knowledge Hub
Compatibility: Compatible with trailer applications where the 11.5" retracted height, 17.5" extended height, 6" lift, mounting base, and capacity match the trailer setup. Verify before ordering.
Vehicle / System Fit: Commonly used on cargo trailers, motorcycle trailers, campers, RVs, utility trailers, and light-duty trailer support applications.
Installation Notes: The jack may be bolted or welded to the inside or underside of the trailer frame or tongue. Hardware is not specified as included.

R&P Repair Insight
When replacing or adding a stabilizer jack, the most common fit issues are mounting clearance, ground clearance, and incorrect use as a lifting jack instead of a stabilizer.
- Stored Position: Confirm the jack locks in the up position and stays clear of the road, trailer body, wiring, and suspension during travel.
- Deployed Height: Compare the 11.5" retracted height and 17.5" extended height against your trailer frame height while parked.
- Support Use: Use as a stabilizer/support jack for a parked trailer. For balanced support, many trailers use one jack on each rear corner.
