Camco ReCurve R3 Weight Distribution Hitch, 400 lb Kit with 2" Ball
Camco ReCurve R3 Weight Distribution Hitch, 400 lb Kit with 2" Ball — Product description
The Camco ReCurve R3 is a weight distribution hitch that takes the load off your tow ball and spreads it across both axles so your rig sits level and tracks straight. This 400 lb kit is sized for lighter travel trailers up to 4,000 lb, with trunnion spring bars, integrated sway control, and a 2-inch ball in the box.
If your travel trailer's got the back of your truck or SUV squatting and the headlights pointing at the treetops, the Camco ReCurve R3 is the fix. It's a weight distribution hitch built to take the load piling on your tow ball and push it back across both axles of the tow vehicle and out to the trailer's wheels. The result is a rig that sits level, steers straight, and stops the way it should.
This is the 400 lb kit. That number is the tongue weight rating, and it pairs with a 4,000 lb gross trailer weight capacity. So this one's sized for the lighter end of the towing world. Small travel trailers, teardrops, grown-up pop-ups, loaded utility and equipment trailers. If you're towing something in that 4,000 lb range and the tongue is pressing 300 to 400 lb down on the ball, this kit is right in its wheelhouse. Tow heavier than that and you'll want to step up to a higher-rated system.
The R3 uses trunnion-style spring bars. They mount on top of the head instead of hanging underneath, which buys you extra ground clearance. That matters more than people think. Steep driveways, gas station aprons, the kind of terrain that'll drag an under-slung bar. The bars themselves are roll-tapered, meaning they flex progressively across five different thicknesses along their length. As your tongue weight shifts around, from a full fresh water tank to an empty one, the taper keeps the load spreading evenly instead of all-or-nothing.
Sway control is built right in. There's a friction brake pad that clamps around the center spindle, and you set how much resistance you want by tightening a single bolt. Crosswinds, passing semis, the shove you feel when a big rig blows by, that's what the sway control fights. And when you pull off the highway onto a slick ramp or need to back into a tight site, you can disengage it so the head swivels freely at low speed. No fighting the hitch while you're trying to thread the needle backing up.
The kit comes ready to run. You get the 2-inch hitch ball and the adjustable shank in the box, so there's no hunting for the last few pieces after it shows up. The shank lets you set head height and tilt to match your tow vehicle, which is how you actually dial in a level tow. Spring bars are 30 inches. Setup is the usual weight distribution routine, measure your fender heights loaded and unloaded, adjust the head angle and bar tension until the front of the tow vehicle comes back down where it belongs, then check your work with a tape measure.
Who's this for? Anyone who's towed a trailer that pushes the truck around and wants it to behave. First-timer with a new travel trailer who's white-knuckling it on the interstate, or a weekender who's just tired of the porpoise and the wander. It's not a heavy-hauler, and it's not the kit for a big bumper-pull loaded near a ton on the tongue. Match the rating to your trailer and it'll do exactly what a good weight distribution hitch should do, which is make the whole rig feel like one connected vehicle instead of a truck getting shoved around by whatever's hooked to the back.
One tip from experience: recheck your spring bar tension and ball torque after your first real drive. New chains and hardware settle in over the first hundred miles or so, and a quick check in a parking lot tells you whether anything needs a nudge. After that it's set-and-go for the season.
Camco's been building towing and RV gear for decades, and the ReCurve line is their take on integrated sway plus weight distribution in one head. It's a proven design that doesn't ask you to bolt on a separate sway bar. One kit, one setup, and you're level.

Frequently asked questions
What size trailer is the 400 lb ReCurve R3 kit for?
This kit is rated for 400 lb of tongue weight and 4,000 lb of gross trailer weight. It's sized for lighter travel trailers, teardrops, and loaded utility trailers. Your loaded tongue weight should land at or below 400 lb. If it's heavier, step up to a higher-rated kit.
How do I know my tongue weight?
Tongue weight is the down force your loaded trailer puts on the ball, usually around 10 to 15 percent of the total trailer weight. Weigh it at a scale or with a tongue weight scale after the trailer is packed the way you tow it. Match that number to the 400 lb rating on this kit.
Does this hitch include the ball?
Yes. The kit ships with a 2-inch hitch ball and the adjustable shank, so you have the main pieces you need to set it up. You just fit it to your receiver and dial in the head height for a level tow.
What is trunnion style and why does it matter?
Trunnion spring bars mount into the top of the head rather than hanging beneath it. That gives you more ground clearance under the hitch, which helps on steep driveways, gas station aprons, and uneven terrain where an under-slung bar can drag.
How does the built-in sway control work?
A friction brake pad clamps around the center spindle of the head. You set the resistance by tightening a bolt. That friction resists the side-to-side sway from crosswinds and passing trucks. It can be disengaged for low-speed maneuvering and slippery conditions.
Can I back up and turn tightly with this hitch?
Yes. The sway control is designed to disengage for low-speed situations, so the head can swivel freely while you back into a site or make tight turns. You re-engage it before you get back up to highway speed.
What size receiver does it fit?
The included shank is made for a standard 2-inch by 2-inch trailer hitch receiver, which is the most common size on trucks and SUVs rated for this class of towing. Confirm your receiver opening before ordering.
How long are the spring bars?
The spring bars measure 30 inches. They're roll-tapered, so they flex progressively along their length to spread the load smoothly as tongue weight shifts, for example between a full and empty water tank.
Do I need to recheck anything after the first trip?
It's smart to recheck spring bar tension and ball torque after your first real drive. New hardware settles over the first hundred miles or so. A quick check in a parking lot tells you if anything needs a small adjustment, then you're set for the season.
