fast service ,thank you!!! 690215

this is the only jack I could find w/ a 3 point center mount and a steel wheel. Exactly what I was looking for. I would have given 5 starts but it did take almost 6 months to get. I would have canceled but it was the only one I could find and etrailer immediately and completely respond every time with updates when emailed for an update. I would do business with them again 481212

this is a great jack for light tongue weights only. It's simply to hard to crank with heavy (over 800)lbs 129476


Ask the Experts about this Bulldog Trailer Jack

  • Is the Rack Post for the 1,200 lb and the 750 lb Bulldog Rack-and-Gear Jacks the Same
    Yes, the rack post for both the 1,200 lb # BD165411 and the (discontinued) 750 lb BD165311 Bulldog Rack-and-Gear Jacks are interchangeable and that the weight rating won't be affected either way. I reached out to my contact at Bulldog who confirmed this and that the only difference (aside from color) is that the gear ratio is a little different so one will operate the let faster than the other one.

  • Need Replacement Wheel For Shelby Jack On 2005 Aliner Camper
    We do not carry replacement wheels for a Shelby trailer jack. I have attached a link to the product page for the jack wheels we do offer. If you are unable to find a replacement that will work you may be interested in replacing the jack. I have attached a link to our product page for the trailer jacks we offer.

  • Replacement A-Frame Caster Wheel Tongue Jack
    We offer all kinds of trailer jacks including the caster wheel a-frame type. Based on my research this is the type supplied on the 2007 Brenderup Baron. For a 1200-lb-rated heavy-duty side-wind jack with 16-inches of lift and a steel wheel you can use Bulldog # BD165411. If you need more lift you can use # BD165412 with 19-inches of lift. Both of these jacks can be bolted or welded on. You may care to have a look at the linked article on trailer jacks to help you choose a suitable replacement...

  • Comparing Rack and Gear Trailer Jacks with Regular Jacks
    If you are looking at a rack and post such as # BD018006 it is just a replacement for the post in a rack and gear jack. A rack and gear jack such as # BD018161 works along with # BD018006. This one gets welded to the frame. Jack # BD169201 clamps to the frame, and one like # BD165411 bolts in as an A-Frame jack. Unlike a typical jack that has a fixed nut inside and a screw that turns in it to raise/lower the inner leg, rack and gear jacks have the gear track fixed to the post and...

  • Replacement Caster Wheel Jack for 2 Horse Slant Trailer
    If your horse trailer's jack has a caster wheel it is probably a bolt-on tongue jack like Bulldog # BD165412 or # BD165411 rather than a weld-on jack like # 3370091410H. These two Bulldog jacks are both rated for 1200-lbs of trailer tongue weight (appropriate for your 7K trailer) and both have a steel wheel; the only difference is the amount of lift which is 16-inches with # BD165411 and 19-inches with # BD165412. Both use a 3-bolt mount as shown in the photo.

  • Does Bulldog A-Frame Gearbox and Crank Assembly Fit Different Size Jack Legs?
    The Bulldog A-Frame Gearbox and Crank Assembly # BD019141 is designed to work with Bulldog Heavy-Duty, Rack-and-Gear Jack # BD165411 and # BD165412. Each of these have an inner tube diameter of 2" and outer tube diameter of 2-1/4" so there is no difference in that regard, and the jacks each have a 1,200 lb capacity.

  • Comparing Bulldog Rack-and-Gear Jack Replacement Gear Box/Crank Assemblies BD019141 and BD018155
    Both of the Bulldog replacement gear box/crank assemblies you referenced, parts # BD019141 and # BD018155, fit their 165-series rack-and-gear jacks. The difference between them is the weight rating of the jacks they fit. Part # BD018155 fits the 750-lb-rated jack # BD018520. Part # BD019141 fits 1200-lb-rated jacks # BD165411 and # BD165412. Both allow either bolt-on or weld-on installation on any standard a-frame trailer.

  • What is the Circumference of Dutton-Lainson A-Frame Trailer Jack, # DL22530
    The outer tube of a jack is usually measured in diameter. The diameter of the Dutton-Lainson A-Frame Trailer Jack, # DL22530, is 2 inches. If you take the diameter and multiply it by pi to get the circumference, it ends up being 6.28 inches. You would need a jack that measures 2 inches to 2-1/16 inches in diameter. I went out to the warehouse and all of the smaller A-frame jacks I measured had that 7 inch circumference. However, I do believe I have a solution for you. While I was out...
