Ask the Experts about this Bulldog Trailer Jack

  • Recommended Trailer Jack Replacement With Snap Ring And 1/2 Inch Plunger Pin
    I confirmed with Cequent that all of their snap rings are the same size, so you can swap your Fulton jack with the Bulldog jacks. The Bulldog Round, Snap-Ring Swivel Jack - Topwind - 15" Lift - 5,000 lbs, # BD171412, you referenced is a great jack that I recommend for your application. The foot plate will help reduce the pressure on the pin as you mentioned as there will be far less movement with the welded foot plate than with the wheel. This jack is made to comply with commercial and...

  • Looking for a Replacement Trailer Jack for a Magic Tilt Trailer with a RAM 2,000 lb Jack
    From what I could find, most Magic Tilt trailers use bolt-on swivel jacks. The only swivel jacks that we carry with a weight capacity over 2,000 lbs are weld-on jacks like the Bulldog Snap-Ring Swivel Jack, # BD171412. This jack has a bracket that welds to the trailer frame and uses a snap-ring to swivel around the weld-on bracket and it uses a foot plate base rather than a wheel caster. I have attached a review video of this jack for you to check out. We are not a dealer for RAM jacks,...

  • Availability of Jack to Replace Bulldog Jack that Installs on Snap Ring Mount
    Sounds like you have a jack like the part # BD171412 and want to replace it with a jack that will use the same snap ring style of attachment. If you went with the part # BD151464, which is very similar to the first jack I mentioned except doesn't come with the weld on mount, you'd be able to install this jack on to your current mount and you'd be set.

  • Trailer Jack Recommendation for Boat Trailer 8,500 Pound Gross Towing Weight
    When choosing a jack for your trailer, you want to choose one that surpasses the tongue weight of the trailer when it is fully loaded. The tongue weight of the trailer is typically between 10 - 15 percent of the weight of the trailer. A jack that easily surpasses your trailer's tongue weight is certainly okay to use. I recommend the Bulldog Round, Snap-Ring Swivel Jack - Topwind - 15 Inch Lift - 5,000 Pounds # BD171412. This jack will weld on like your existing jack, and it is also...

  • Bulldog 5k Rated Bulldog Jack with Mount and Foot Plate
    For a version of the part # BD1701480317 that comes with a foot plate and a mount you would want the part # BD171412. Otherwise you could use the weld on pipe mount part # BD500240.

  • Recommendation for a 2,000 Pound Capcity or Higher Snap-Ring Swivel Trailer Jack
    I went out to the warehouse and pulled the 2 jacks that would most likely fit and meet the needs of your application. First, I measured the Pro Series Round, Snap-Ring Swivel Jack, # PS1400300303, that you have referenced. This jack has a bolt hole pattern of 4-1/2 inches vertically and 5-3/8 inches horizontally (the mounting plate can be turned to flip those measurements). This is a 2,000 pound capacity jack with 10 inches of lift. Next, I measured a higher capacity 5,000 pound jack,...
