Difference Between # UF39-941705 And # UF39-941707 Ultra-Fab Stabilizer Jacks  


Are the 30 inch model UF39-941705 Stabilizer II made of stronger material than the 22 inch model UF39-941707


Expert Reply:

The lift capacity and strength is the same for either of the power stabilizers you referenced. They both have dual motors which operate independently, making it easier to level the motorhome or trailer. The difference is the lift distance and what size trailer they will fit.

The Ultra-Fab Power Twin II Electric Stabilizer, part # UF39-941707, has a 22 inch lift capacity and is designed to fit trailers with a frame with between 42 and 77 inches.

The Ultra-Fab Power Twin II Electric Stabilizer with Dual Motors, part # UF39-941705, has the same weight capacity of 6,000 lbs and has a lift of 36 inches and designed to fit trailer frames from 48 to 80 inches wide.
