Fifth wheel hitches for your
2018 GMC Sierra 2500

The A30 is a 30K A-Series fifth wheel that bolts to industry-standard rails, so you'll need those in the bed for this long-bed setup. The spherical articulating head and heavy capacity make it a strong value for big fivers on a rail-equipped truck.

The 27K M5 in rail form bolts to industry-standard rails, so you need those in the bed first. Once mounted it tows like the puck version with firm dual-jaw grip, a good heavier-duty option for trucks already running rails.

A 25K A-Series rail-mount fifth wheel with the fully-pivoting spherical head, requiring standard rails in the bed. Great capability per dollar and a stable tow, our value pick for rail-based heavy haulers.

The Q25 is Curt's step-up 25K rail-mount fifth wheel with a dual-pivot head that cushions road chucking better than the A-Series. It bolts to industry-standard rails and offers a smoother, quieter tow for a modest price bump.

The 25K TrailSaver is the rail-mounted air-ride option, requiring industry-standard rails in the bed. It tows as smooth as the puck versions thanks to the air bag, but it's heavy to wrestle in and out and carries the usual Hensley premium price.

The Q24 is a 24K rail-mount fifth wheel with Curt's dual-pivot head for better cushioning than the A-Series. It needs standard rails in the bed and delivers a smoother tow at a fair price for medium-heavy fivers.

Blue Ox's 24K fixed fifth wheel bolts to industry-standard rails, so you'll need those in the bed already. Solid mid-tier build and capacity for most heavy fivers, but it doesn't cushion road chucking the way a B&W Companion or air-ride pin box does.

The 24K ISRX SuperLite is the lighter rail-mount option for ISR-equipped beds, keeping the 24,000-lb rating while shaving weight for an easier lift. Ride is a touch less plush than the Super 5th, and the value tips slightly more in your favor.

The 24K ISRX Super 5th is a fixed rail-mount head designed for ISR rail systems, rating 24,000 lbs with the premium Super 5th build. Solid and quiet on the road, provided your bed already has the ISR rails to bolt it to.

The 24K Super 5th in rail-mount form needs industry-standard rails in the bed, then locks in fixed for a 24,000-lb tow. Premium build and a quiet, low-chuck ride, just be sure your truck already has the rails before you buy.

The Recon 21K is Demco's fixed fifth wheel built for industry-standard rails already in the bed, so it bolts down without the puck system. Dependable build and good value, but you'll need existing rails and the ride is solid rather than plush.

This Recon 21K ships with the rails included, giving you a complete fixed fifth-wheel package for a non-puck truck. Capable and fairly priced, though it's a fixed head with no slide and the tow won't soak up bumps like a cushioned unit.

A 20K Super 5th rail-mount fixed head for mid-weight fivers, requiring standard bed rails and then locking in tight with minimal chucking. Premium engineering at 20,000 lbs, with the usual caveat that you supply the rails.

The Q20 rail-mount is Curt's step-up 20K fifth wheel with a dual-pivot head that smooths out chucking better than the A-Series. It bolts to standard rails and gives a quieter tow for a small premium over the base line.

A 20K A-Series rail-mount fifth wheel with the spherical articulating head, requiring industry-standard rails in the bed. Solid value for mid-weight fivers and a stable, full-articulation tow.

A 20K M5 designed for standard fifth-wheel rails rather than pucks, fitting the most common setups. Solid build and a quiet, stable tow, though it's heavier to wrestle in and out than a puck unit since it locks to the rails.

The 20K SuperLite is a lighter rail-mount fixed head rated for 20,000 lbs, easier to wrestle in and out than the Super 5th while keeping strong build quality. It bolts to standard rails and tows well, trading a little ride refinement for the lower weight.

This is the 20K Companion configured for industry-standard rails, so it needs rails already bolted in the bed. Once mounted it tows with the same cushioned, articulating head and chucking-free ride as the puck versions.

An 18K rail-mount TrailSaver that bolts to standard rails and uses air suspension to eliminate chucking. The ride is best-in-class and the build is overkill in the good way, but expect heavy lifting at install and a steep cost.

The 18K Patriot is B&W's rail-mount value fifth wheel, a solid step below the Companion in ride refinement but still well-built and stable. It bolts to standard rails and locks securely; a sensible pick if you already have rails and don't need the cushioned head.

The 16K Patriot is the lighter-rated rail fifth wheel for smaller fivers, sturdy and dependable on existing rails. It tows well for the money but lacks the cushioning and full articulation that set the Companion apart.

A 16K Super 5th rail-mount fixed head for lighter fifth wheels, delivering PullRite's tight, quiet tow on industry-standard rails. Great hardware at 16,000 lbs, just confirm the bed rails are already in place.

The 16K dual-jaw is Reese's basic rail-mount fifth wheel, bolting to industry-standard rails for a no-frills tow. It does the job at a friendly price, but the simpler head lets more chucking through than the M5 and there's no extra cushioning.

The E16 is Curt's budget 16K rail-mount fifth wheel with a single-pivot head, requiring standard rails in the bed. It tows lighter trailers fine for cheap, but expect more chucking and less articulation than the A or Q lines.

The 16K M5 is the lighter rail-mount in the line, suited to smaller fifth wheels on standard rails. It keeps the same dual-jaw head and composed ride, a reasonable rail option when you don't need big capacity.

A 16K A-Series rail-mount fifth wheel for lighter fivers, with the spherical articulating head and a need for standard rails in the bed. Excellent value at the lower capacity tier with smooth, full-direction articulation.

This 30K Turnoverball fits 16-19 Chevy/GMC 2500/3500 and uses the signature flip-over ball for a flush, usable bed. It bolts to factory points for a strong connection that doesn't clatter down the road.

The Double Lock EZr is a 30K under-bed gooseneck for GM 2500/3500, with a dual-locking ball that drops in or stows flush when you want a flat bed. It's our value gooseneck pick, solidly built and easy to live with, though under-bed install is more involved than a puck hitch.

The 24K Super 5th here mounts onto an existing gooseneck ball, turning a gooseneck-equipped truck into a 24,000-lb fifth-wheel rig without rails. Premium build and a quiet ride, and it's an easy drop-on if you've already got the ball in the bed.

This Recon 21K Flat Deck mounts a fifth wheel onto a recessed gooseneck ball, keeping the bed flat when the hitch is off. Easy to drop onto an existing ball at a fair price, though it's fixed-head only and the tow is solid without being smooth.

The Recon 21K Gooseneck Ball-Mount lets you run a fifth wheel off any existing 2-5/16in gooseneck ball, so it drops on without a rail or puck install. Versatile and good value, but it's a fixed head with no cushioning and articulation is just adequate.

This 21K head drops onto an existing gooseneck ball, letting you run a fifth wheel off an under-bed gooseneck without rails. Decent build and easy to set in or pull out, though the gooseneck-ball mount transmits more chucking than a dedicated rail or puck setup.

The 20K SuperLite is a lighter gooseneck-ball fifth-wheel head that drops onto an existing ball for a 20,000-lb tow with no rails required. Easier to handle than the Super 5th and a bit cheaper, with only a slight give in ride smoothness.

The Recon Stealth 20K is a folding gooseneck ball-mount that sets a fifth wheel onto any 2-5/16in ball and folds down for a clear bed. Handy and well-priced for ball-mount towing, but the 20K fixed head trades a bit of capacity and ride polish versus dedicated puck units.

The Gen 3 Goose Box (20K) swaps your trailer's pin box for an air-ride gooseneck coupler, freeing up the truck bed entirely. The air cushion smooths the ride and cuts chucking, making it the standout pin-box conversion if you'd rather pull a fiver off a gooseneck ball.
