Eaz-Lift ReCurve R3 Weight Distribution Hitch, 400 lb Kit (48750)

If your travel trailer feels like it's dragging the back of your truck down and steering gets light over 55, you don't have a truck problem. You've got a weight problem, and that's exactly what the Eaz-Lift ReCurve R3 from Camco is built to fix. This is the 400 lb kit, part number 48750, rated for trailers up to 6,000 pounds gross with a maximum tongue weight of 600 pounds. It takes the load piling up on your hitch ball and spreads it back across your truck's front axle and your trailer's axles, so the whole rig sits level and tows the way it should.

Here's what's actually happening. When you hook up a loaded trailer, all that tongue weight pushes down at the very back of your truck. The front end lifts, your headlights aim at the trees, and your front tires lose grip right when you need it for steering and braking. The ReCurve R3 uses a pair of trunnion spring bars that tension against the trailer frame and lever that weight back to where it belongs. You end up with a truck that sits flat, steers predictably, and stops shorter.

The R3 part is the sway control, and it's built right into the head. Camco uses an adjustable friction collar lined with brake-pad material. You tighten the clamp down for more resistance against sway, or back it off if you want less. That means you tune it to your trailer and your driving conditions instead of living with a fixed setting. Crosswinds on the interstate, the push from a passing semi, a gust off an open field, the friction collar damps that side-to-side motion before it builds into a white-knuckle wobble.

One thing RVers appreciate: you can shut the sway control off completely. Backing into a tight site with the friction engaged fights you the whole way, so you loosen the collar and let the trailer pivot freely. Same deal on ice, a wet ramp, or a slick gravel apron where you actually want the trailer to move a little instead of the hitch binding up. Thirty seconds by hand and you're set either way.

The trunnion bars top-load into the head rather than hanging underneath. That's a real advantage for ground clearance. If you've ever scraped a hitch on a steep driveway transition or a gas station apron, you know why it matters. The bars ride higher, so you clear more.

The kit is complete out of the box. You get the head assembly, the two trunnion spring bars, an adjustable shank that slots into a standard 2-inch receiver, and a pre-installed 2-5/16 inch hitch ball rated to 15,000 pounds. No hunting for a ball at the parts counter, no guessing on the rating. The adjustable shank lets you set the head height up or down so you can get the trailer sitting dead level before you ever tension the bars.

Sizing is straightforward. This 400 lb kit is happiest when your fully loaded tongue weight lands in the neighborhood of 400 pounds, and it'll carry up to 600 pounds maximum. Tongue weight usually runs 10 to 15 percent of your loaded trailer weight, so a trailer scaling around 4,000 to 5,500 pounds loaded is the sweet spot. Weigh your rig loaded for a trip, fuel, water, and gear included, not the dry number off the sticker. If your loaded tongue weight is climbing past 600 pounds, step up to a heavier bar kit in the ReCurve R3 line.

Who's this for? Owners of mid-size travel trailers pulling with a half-ton pickup or a capable SUV who want the rig to tow flat and stay planted without paying for a shop install they can do themselves in an afternoon. It's a proven design, it comes with a 5-year limited warranty from Camco, and it does the two things that matter most on a long tow: keeps you level and kills sway before it starts.
