The Bulldog 500180 is the genuine replacement for the 150, 160, and 170 series topwind jacks rated 2,000 to 5,000 pounds.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Bulldog 500180 is the genuine replacement part for Bulldog's 150, 160, and 170 series topwind trailer jacks, the ones rated to handle 2,000 up to 5,000 pounds of tongue load. If your topwind jack has seen a few seasons of cranking a loaded trailer up and down the ramp, and the crank has gone stiff or sloppy, this is the part that gets you back to a smooth lift. Bulldog builds this line tough for exactly that kind of duty.\u003c\/p\u003e\n\u003cp\u003eIt's built for the topwind style, where you crank from the top of the jack rather than the side. The handle throws on a 6-3\/4 inch radius, so you get the same mechanical advantage the jack came with from the factory. That radius matters more than people think. Too short and you're fighting the weight the whole way up. This one's matched to what Bulldog spec'd for these jacks, so the effort feels right and the lift stays controlled.\u003c\/p\u003e\n\u003cp\u003eFitment is the whole game with a replacement part like this. It's made for the 150, 160, and 170 series specifically. If you've got one of those Bulldog topwind jacks on a boat trailer, a utility trailer, or a small equipment trailer in that 2,000 to 5,000 pound range, this goes in where the worn part came off. Not sure which series you have? Check the casting or the label on the jack body, or send us a photo and we'll confirm before you order. Getting the series right the first time saves you a return trip.\u003c\/p\u003e\n\u003cp\u003eWhy go genuine Bulldog instead of a swap-in from the parts bin? Because these jacks carry real load, and a trailer jack that lets go under a loaded tongue is the kind of problem you don't want at the ramp or in the driveway. The factory part is sized and finished to hold up to the same demanding use Bulldog builds all their towing gear for. Get the right part, install it, and forget about it for another few seasons.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGenuine Bulldog replacement part for 150, 160, and 170 series topwind trailer jacks\u003c\/li\u003e\n  \u003cli\u003eFits topwind jacks rated for 2,000 to 5,000 pound capacity\u003c\/li\u003e\n  \u003cli\u003e6-3\/4 inch handle radius, matched to the factory crank effort of these jacks\u003c\/li\u003e\n  \u003cli\u003eTopwind design, cranks from the top of the jack rather than the side\u003c\/li\u003e\n  \u003cli\u003eDirect-fit replacement, goes in where the worn part came off\u003c\/li\u003e\n  \u003cli\u003eBuilt to the same demanding standard as Bulldog's towing and trailering line\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Bulldog reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich jacks does the Bulldog 500180 fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's the replacement part for Bulldog's 150, 160, and 170 series topwind trailer jacks in the 2,000 to 5,000 pound capacity range.
