Camco Eaz-Lift TR3 600 lb Weight Distribution Hitch Kit

If you've ever towed a loaded travel trailer and felt the back of your truck squat while the headlights point at the sky, you already know why a weight distribution hitch matters. The Camco Eaz-Lift TR3 takes the tongue weight that's pushing down on your hitch and spreads it back across the trailer axles and forward onto the truck's front axle. The result is a level rig, steadier steering, and headlights aimed where they belong.

This is the trunnion-bar version of the TR3. The spring bars slide into the head from the side instead of hooking underneath, which gives you a little more ground clearance and a cleaner look at the coupler. We like the trunnion setup on lower-slung trailers and on trucks where you're fighting for every inch under the bumper. The bars in this kit are rated at 600 lb, which pairs well with trailers carrying somewhere in the 400 to 600 lb tongue weight range. The head assembly itself is rated up to 800 lb of tongue weight and 8,000 lb of gross trailer weight, so there's headroom in the casting.

The part that sets the TR3 apart is the built-in dynamic sway control. There's no separate friction bar to bolt on and no extra ball to grease. Sway control is baked right into the head. A collar wraps the pivot point where each bar seats, and a simple adjustment lets you tighten, loosen, or fully release the friction on that pivot. Crank it up on a windy interstate day or when a semi blows past, back it off for tight low-speed maneuvering. It's the kind of thing you set once for your usual route and rarely touch again.

Setup is straightforward for anyone comfortable with a torque wrench. The kit includes the head, the shank, both trunnion spring bars, the lift brackets and hardware, and a 2-5/16 inch hitch ball that comes pre-installed. You'll slide the shank into a standard 2 inch receiver, set your head angle with the washers, mount the lift brackets to the trailer A-frame, and tension the bars. Measure your loaded tongue weight first so you know which hole on the brackets gives you a level stance. Take a lap around the block, check that the truck and trailer sit level, and fine-tune from there.

Who's this for? Owners of mid-size travel trailers, hybrids, and bumper-pull campers that land under the 8,000 lb gross mark. If your trailer's tongue weight runs closer to 800 lb or over, step up to the heavier bar rating in the TR3 line instead. And if you're towing something tiny with almost no tongue weight, you probably don't need weight distribution at all. This hitch earns its keep in the middle, where the trailer is heavy enough to unsettle the truck but still within a half-ton or three-quarter-ton tow rating.

A few honest notes from bolting up plenty of these. Match the shank length and head height to your specific truck and coupler so the bars sit at the right angle. Getting that geometry right is what makes the difference between a hitch that rides smooth and one that clunks. Torque the trunnion and bracket hardware to spec, and re-check it after your first long trip, because everything settles a bit once it's been loaded and unloaded a few times. And keep the pivot points and ball greased. Steel-on-steel friction is doing real work here, and a dry pivot squeaks and wears faster than it should.

The TR3 is a no-drama, mechanical piece of gear. No electronics, no proprietary anything, just a well-made head, forged bars, and an adjustment you can actually feel. Set it up right and it'll pull straight and level for years. If you're not sure which bar rating or shank fits your setup, give us a shout with your trailer's dry tongue weight and receiver height and we'll help you spec it.
