Dimensions of Reese and Ultra-Fab Fifth Wheel Landing Gear


My1998 Fleetwood Avion 375w powered landing gear are junk, bad bevel gears and gearbox bushings are shot, I want to use either the bulldog dual powered legs or the ultra fab legs. Bulldog doesnt have a diagram showing where the mounting tabs are located, or their spacing on the legs, can you tell me, so I will know if they are a direct swap or if i will need to have new brackets welded onto my frame. Thanks

I would be happy to help you with those dimensions.

The Reese Electric 5th Wheel Landing Gear # RP500708 has the standard weld stop measurements that are 15-1/2" from inside to inside of weld stops and 17-1/2" from outside to outside.

The Ultra-Fab # UF17-943010 has weld stop brackets which measure 20-1/4" from outside to outside; it is 8-1/2" from the top of the motor to the first weld point. I have added photos showing the dimensions of these jacks for you to check out.

Apart from the dimensions of the weld stops, the jacks are very similar, with the Ultra-Fab having a 12,000 lb capacity and 38" of lift, compared to the 8,000 lb capacity and 36" of lift for the Reese.
