The spring bars stay attached; to load them you pump the hydraulic handle on the driver's side and watch the gauge until you have moved as much weight onto the truck's front axle as you want. To unhook you twist the needle valve and the pressure bleeds off. Because the bars are tapered composite rather than steel, one set covers the whole 600-1,600 lb tongue weight range, so bringing the ATV home in the trailer does not mean swapping bars, and a small correction is a few more strokes of the handle at the next rest stop rather than a job with a tool. The Continuum is built around a single pivot point, which is where the rattle and the wear go in a conventional weight distribution hitch, and because the bars are always under load its friction sway prevention is working from the first foot of the trip rather than waiting for the trailer to move out of line first. This part number is the 2\" shank version with a standard coupler. Most half-ton and three-quarter-ton trucks leave the factory with a 2\" receiver. The complete kit arrives as two cartons, head unit WDHH4500 and load bar unit WDHL4510, with the 2-5\/16\" ball already fitted.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eContinuum head unit WDHH4500, 2\" shank, with the 2-5\/16\" ball fitted\u003c\/li\u003e\n\u003cli\u003eContinuum load bar unit WDHL4510, standard coupler\u003c\/li\u003e\n\u003cli\u003eTapered LITEFLEX composite spring bars, rated 600-1,600 lb tongue weight\u003c\/li\u003e\n\u003cli\u003eHydraulic pump with pressure gauge, cylinder and hoses\u003c\/li\u003e\n\u003cli\u003eTrailer frame brackets and mounting hardware\u003c\/li\u003e\n\u003cli\u003eHitch pin and clip for the receiver\u003c\/li\u003e\n\u003cli\u003eB\u0026amp;W Continuum installation manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"embed-container\" style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;max-width:100%;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/YDCp4nsG9Ps\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;\" frameborder=\"0\" allowfullscreen\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSet the Weight Transfer With a Pump Handle\u003c\/strong\u003e\u003cbr\u003eConventional weight distribution hitches are loaded or unloaded, and moving between the two means a lever bar and some effort. The Continuum uses a hydraulic hand pump: you pump until the gauge shows the pressure you want and stop. That makes weight transfer a dial rather than a switch, so you can put back exactly as much front axle load as your truck maker asks for instead of whatever the next chain link gives you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOne Set of Bars for 600 lb to 1,600 lb of Tongue Weight\u003c\/strong\u003e\u003cbr\u003eB\u0026amp;W partnered with Hendrickson, which builds suspensions for heavy trucks, for the tapered LITEFLEX composite spring bars. They are about five times more flexible than steel at similar strength, and much lighter, so a single set covers the full 600-1,600 lb tongue weight range. If you tow more than one trailer, or the same trailer loaded differently, you are not buying or storing a second set of bars.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSway Prevention That Is Already Working\u003c\/strong\u003e\u003cbr\u003eB\u0026amp;W tested the leading friction sway control systems on air casters in a warehouse and found that most of them take very little force to overcome, and that several do not begin to resist until the trailer is already 2 to 4 degrees out of line, which on a 25' trailer is several feet of lane. The Continuum's bars are always loaded, so its friction resistance is present continuously rather than arriving after the sway starts. That is where the name comes from.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA Repeatable Setup You Can Read Off a Gauge\u003c\/strong\u003e\u003cbr\u003eThe head angle is preset at the factory and there is nothing to shim, so the only variable is pressure, and pressure is on a dial. Note the number that works for your truck and trailer and you can reproduce the same setup every trip in under a minute, including after someone else has hitched up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEverything Happens on the Driver's Side\u003c\/strong\u003e\u003cbr\u003eThe pump, the gauge and the needle valve are all on the driver's side of the trailer. You are not walking around the tongue in the rain, or kneeling on the road side of the rig at a highway pull-off, to get the bars on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2\" Shank With a 2-5\/16\" Ball Fitted\u003c\/strong\u003e\u003cbr\u003eThis part number is the 2\" version. Most half-ton and three-quarter-ton trucks leave the factory with a 2\" receiver. The 2-5\/16\" ball comes standard on every Continuum, and the head unit can be inverted in the receiver if your trailer sits higher than the ball. B\u0026amp;W does not publish a height figure for the inverted position, so measure your own setup rather than working from a number.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuilt to Come Apart When You Do Not Need It\u003c\/strong\u003e\u003cbr\u003eThe spring bar assembly lifts off, so if you hook up a small trailer that does not need weight distribution you can tow on the ball mount alone rather than swapping hitches. B\u0026amp;W also reports more turning clearance than most leading brands with the bars attached, so backing into a site does not mean disconnecting first.\u003c\/p\u003e\n\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x:auto;margin:8px 0 4px;border:1px solid #e6e6e6;border-radius:8px;\"\u003e\u003ctable style=\"display:table;width:100%;margin:0;border-collapse:separate;border-spacing:0;border:none;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"background:#ba232a;color:#ffffff;text-align:left;padding:12px 14px;font-weight:700;border:none;\"\u003eWhat Has To Match\u003c\/th\u003e\n\u003cth style=\"background:#ba232a;color:#ffffff;text-align:left;padding:12px 14px;font-weight:700;border:none;\"\u003eThis Kit\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;font-weight:600;\"\u003eTruck receiver size\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e 2\" receiver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;font-weight:600;\"\u003eTrailer coupler style\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e Standard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;font-weight:600;\"\u003eTrailer tongue weight\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e 600 lb to 1,600 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;font-weight:600;\"\u003eTrailer gross weight\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e Up to 16,000 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;font-weight:600;\"\u003eTrailer frame\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e 5\" or 6\" with no center rail; 4\" or 7\" with different cylinder mount hardware\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;font-weight:600;\"\u003eClear frame needed ahead of the brackets\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e 2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;font-weight:600;\"\u003eHitch ball\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e 2-5\/16\", included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003cdiv style=\"background:#faf7f7;border-left:4px solid #ba232a;border-radius:0 8px 8px 0;padding:14px 16px;margin:12px 0;\"\u003e\u003cp style=\"margin:0;\"\u003e\u003cstrong\u003eFit guidance:\u003c\/strong\u003e The Continuum is a universal-fit weight distribution hitch, not a vehicle-specific kit. Three things decide whether this part number is the right one, and none of them is the year and model of your truck. First, the receiver: this kit has a 2\" shank, so your truck needs a 2\" receiver. Second, the coupler on your trailer: this kit is built for a standard coupler, the common style where the coupler sits on top of the trailer's A-frame. Third, the trailer frame: the Continuum fits 5\" and 6\" frames that do not have a center rail, and 4\" and 7\" frames with different cylinder mount hardware, and it needs 2\" of clear frame ahead of where the brackets land. The hitch arrives with a 2-5\/16\" ball fitted.

The idea was simple and nobody else had done it: a gooseneck ball that turns over and stores flush with the bed floor, so the truck bed goes back to being a truck bed the moment you unhook. That one product built the company, and B\u0026amp;W still makes its hitches in Humboldt, in a plant that has grown to about 600,000ft². The company has been 100% employee-owned since 2007, with roughly 500 employee-owners who have a stake in what comes off the line.\u003c\/p\u003e\n\u003cp\u003eThe testing story is worth knowing, because it is not how the rest of the industry does it. SAE J-2638, the standard for gooseneck and fifth-wheel hitches, is a recommended practice, and it is common to satisfy it with a fresh sample for each test. B\u0026amp;W runs a single hitch through all three 300,000-cycle dynamic tests and the six static tests, one after another, on the same unit. The Tow \u0026amp; Stow line is tested to SAE J-684. Every B\u0026amp;W-brand product is covered by the company's Lifetime Exclusive Limited Warranty to the original consumer, against defects in material and workmanship, for as long as that person owns it.\u003c\/p\u003e\n\u003cp\u003ePrestige Truck is an authorized B\u0026amp;W dealer.
