Replaces the dual-output motor for Bulldog electric fifth wheel landing gear (BD500161, BD500170).


I have used the Bulldog jacks for my RV for about 2 or 3 years. I have a 36 ft 5th wheel and although I had a failure in the motor, the company warrantied them and sent me Replacements without much ado. I was required to pay return shipping which can be a little pricey for a heavy item for the both motors it was $30 but I'm happy to have two brand new replacement motors and that's not too much to pay. I would have a good review for this product.


I noticed one of my landing gear motors was slower than the other and making an unhappy noise. Etrailer had it in stock and sent it right out. The part arrived damaged. I called them up and was pleasantly surprised by the outstanding customer service. A replacement arrived quickly. These folks are serious about their business and customers! I will not hesitate to order from them when I need RV parts.


Works great


This small unit is very strong, I actually integrated this gear motor to a side mount jack for a camper. I had some custom shafts made to be able to join the two units. Works like a charm. With this motor on a real jack, the junk scissor jacks that come on a camper are now gone. 4 of these setup on my design actually will pickup the entire camper (9,000 lbs).


Works great! Ordered another one for the other side a month ago.


Expensive but worked


Excellent service, and the motor/gearbox arrived in short order. Overall a very good experience!


Super fast delivery. Very helpful Michael was in getting the part to us ASAP.



Great product, bought to use as a spare but have had no problems with the initial purchase. Love the separate motors for each jack.


Works great so far. Just what I needed. Thanks!



On time and correct part!! Great services!! Thank you!!



Great product and fast shipping!

  • Can Replacement Motor for Bulldog Electric 5th Wheel Landing Gear # BD500359 Be Exposed to Rain
    Landing gear motors like the Replacement Dual Output Motor for Bulldog Electric 5th Wheel Landing Gear # BD500359 that you referenced were designed to withstand rain and snow as they install on the outside of a trailer. You would not need to build a covering for the motor. If you can limit exposure to water it wouldn't hurt but it's not something that will fail the first time it gets rained on.

  • Bulldog Jack Motor Replacement Capacities
    The Replacement Dual Output Motor for Bulldog Electric 5th Wheel Landing Gear # BD500359 that you referenced has a high and low speed on it. The higher speed is for jacking a trailer up quicker and the lower speed has more leverage over the trailer's pin weight which means it's not working quite as hard. It just moves slower. The kit this motor fits gives you a 10k capacity. There isn't a higher capacity jack motor for this setup available. If instead you were referring to the part #...

  • Replacement Motor for Bulldog Landing Gear Motor 1046104
    I have a solution for you, but the # BD1046130-00 is designed for a single speed electric jack. To replace landing gear with the motor 1046104 you'll want to use the Replacement Dual Output Motor for Bulldog Electric 5th Wheel Landing Gear # BD500359. This is the exact replacement part for your landing gear and was confirmed by my contact over at Horizon Global, who own Bulldog.

  • Solution for Needing Replacement Motor for Fulton Trailer Landing Gear
    I did some checking and the Fulton line of landing gear was discontinued in 2000 and there are no longer any replacement parts listed for it. I wish there was just a motor kit I could recommend for you but you'll have to look into a new set of powered landing gear. For a replacement we have the Stromberg Carlson part # LG-4 which will match the bracket dimensions you have now and has a 6,500 lb capacity which means it will raise and lower your trailer quickly and last a long time due...

  • Bulldog Dual Output Motor 500359 Speed and Compatibility on Custom Application
    The Replacement Dual Output Motor for Bulldog Electric 5th Wheel Landing Gear # BD500359 is 7.75 x 6.50 x 4.75 Inches. The speed of the motor is either 45 RPM or 60 RPM on high speed which on high speed will give you 9 inches of lift per minute. The compatibility is actually a difficult question as the Bulldog system has been discontinued but replaced with a similar Reese System. The Reese Electric 5th Wheel Landing Gear Set - 36" Lift - 8,000 lbs # RP500708 is the complete landing gear...

  • Bulldog 12000 lb Powered Electric Jack Replacement Motor
    To replace just the motor for your 12000 lb Bulldog single-speed jack (like # BD182815) you will just need motor # BD1046130-00. I've attached a video of the motor being installed for your convenience. To replace the dual-output motor for Bulldog electric 5th-wheel landing gear (like # BD500161), use part # BD500359.

  • Powered Bulldog Jack/Motor Recommendation for a Farm Implement
    If you have a set of 12k capacity Bulldog landing gear on your farm implement you could use the # BD1824200100 as a motor if the jack is single speed, or part # BD1824180100 if the jack is 2 speed. This would be a solution if the implement has a gooseneck style of coupler. If you have an A-frame trailer you would need to upgrade the current jack to a part # BD500187. The motor of the # BD500161 is available separately, part # BD500359. However, this can't be modified to fit a non-powered jack.
