Wheel Chocks That Actually Hold on a Slope
MAXXHAUL 70075 solid rubber chocks take the top spot for weight and grip on both concrete and gravel. Camco X-Chock is the specialist pick for tandem axle RVs. Camco Heavy Duty chocks are the practical value choice for lighter vehicles.
MAXXHAUL 70075 solid rubber chocks are the ones to buy for most trailers and vehicles. Camco X-Chock handles tandem axle RVs specifically, and Camco Heavy Duty chocks make sense when weight and storage space matter more than outright grip.
A lightweight plastic chock rated for a small trailer will simply slide across smooth concrete under a loaded RV, and a chock too short for a large tyre acts as a ramp rather than a stop. That is exactly why wheel chocks look like a commodity yet trip up so many buyers. Published material, weight and tyre size ratings all factored into this ranking, alongside consistent owner reports about slipping and cracking, weighting grip on real surfaces and load rating over price.
What we recommend
MAXXHAUL 70075 Solid Rubber Heavy Duty Wheel Chock
Solid rubber is the material that separates a chock that works from one that skates, since the weight keeps it in place and the compound grips concrete rather than sliding on it. These feel substantial in the hand, and a moulded handle means no scrabbling under a bumper to retrieve them. Owners report them holding trailers and vehicles on sloped drives where plastic chocks moved.
Pros
- Weight and compound grip concrete reliably
- Moulded handle makes placement easy
- Ribbed face bites into the tyre tread
Cons
- Heavy to carry as a pair in a boot
- Rubber leaves marks on pale garage floors
Camco X-Chock Tire Locking Chock
A completely different principle drives this design, wedging between the two tyres of a tandem axle and expanding with a ratchet to push them apart. That removes the rocking motion that makes an RV feel unstable when you walk around inside it. It does not replace conventional chocks for parking on a slope, but it solves a problem no ordinary chock addresses, and it only fits tandem axles with adequate tyre spacing.
Pros
- Removes side to side rocking in an RV
- Ratchet operation is quick and tool light
- Works alongside conventional chocks
Cons
- Only useful on tandem axle trailers
- Needs sufficient clearance between tyres
Camco Heavy Duty Wheel Chock
Moulded plastic makes up the chocks you see behind most travel trailers, and for lighter loads on level or gently sloped ground they do the job at a fraction of the weight of rubber. They stack for storage and will not scuff a garage floor. The honest limitation shows up on smooth wet concrete under a heavy load, where plastic can slide where rubber grips.
Pros
- Very light to carry and store
- Stackable design saves space
- Will not mark a garage floor
Cons
- Can slide on smooth wet concrete
- Plastic becomes brittle after years outdoors
Buyers Products RC1815 Rubber Wheel Chock
Buyers Products supplies the commercial truck trade, and this chock reflects that with a large rubber body and the mass needed to hold a loaded vehicle. It runs considerably bigger than a typical trailer chock, which matters once a tyre is tall enough that a small chock simply lifts and rolls over. Storage and lifting are the practical trade offs.
Pros
- Sized correctly for large truck tyres
- Substantial weight resists sliding
- Built for commercial duty cycles
Cons
- Heavy and awkward to store
- Oversized for cars and small trailers
AFA Tooling Wheel Chocks
Home mechanics who need something reliable behind a wheel while working under a jacked vehicle are the target for these, with a moulded rope handle for retrieval and a compact size that fits in a boot. They grip concrete well, and the size suits passenger cars and light trailers. Think of them as a good complement to jack stands rather than a substitute for them.
Pros
- Reliable grip for garage and driveway work
- Rope handle simplifies retrieval
- Compact enough for boot storage
Cons
- Too small for large truck tyres
- Rubber can transfer marks onto flooring
Homeon Wheels Heavy Duty Wheel Chocks
Reflective strips and carry handles come on these rubber chocks at a price closer to plastic than premium rubber, making them an easy upgrade from moulded plastic. The reflective element genuinely helps when chocking a trailer at the roadside at night. Rubber quality rates fair rather than exceptional, and storage out of direct sun extends their life.
Pros
- Reflective strips aid roadside visibility
- Rubber grip at close to plastic pricing
- Handles make placement straightforward
Cons
- Rubber compound is softer than premium chocks
- Reflective strips wear off with rough use
Fasmov Solid Rubber Wheel Chocks
Motorcycles, small trailers and passenger cars suit these compact rubber chocks best, where a full size chock is overkill and storage space is limited. Solid rubber construction still grips far better than plastic of the same size. A caravan or a loaded truck is the wrong application here, and the sizing makes that obvious.
Pros
- Compact enough to keep in any vehicle
- Rubber grip in a small footprint
- Sensible price for a pair
Cons
- Undersized for large tyres
- Not suitable for heavy loaded trailers
Before you buy
How to size a chock to the tyre, not the vehicle The industry rule of thumb sets a chock at roughly a quarter of the tyre’s height. Anything shorter and the tyre can climb over it, turning the chock into a small ramp instead. Measure the tyre diameter and check the chock’s rating rather than assuming a chock sold for trailers fits your trailer, since tyre sizes vary enormously between a small utility trailer and a loaded fifth wheel.
Rubber vs plastic vs metal, and where each one fails Weight and a compound that grips concrete and asphalt are why solid rubber chocks hold under load and on slopes. Moulded plastic chocks run light, stackable and cheap, working perfectly well on level ground with modest loads, but they can slide on smooth wet concrete and grow brittle after several years of ultraviolet exposure. Metal chocks are strong but can slide on hard surfaces without a rubber pad. Match the material to the surface you park on.
Placing chocks correctly for the situation Chock the wheels in the direction the vehicle would roll: downhill side on a slope, both sides if the ground is level or the situation is uncertain. Push the chock firmly against the tyre so there is no gap, since even a small run up lets the vehicle build enough momentum to climb over. On a trailer, chock the wheels before unhitching, not after, and use chocks on both sides of at least one wheel whenever the trailer will sit unattended.
Why chocks are not a substitute for jack stands This is worth stating plainly: chocks stop a vehicle rolling, but they do not hold weight. Any time you go underneath a vehicle, it must sit on properly rated jack stands on solid level ground, with chocks used on the remaining ground wheels as an additional precaution. Relying on a jack, a chock, or both together to support a vehicle you are underneath is how people get seriously hurt.

Good to know
What size wheel chock do I need?
Aim for a chock roughly a quarter of your tyre’s height. Measure the tyre diameter and compare it to the manufacturer’s rating rather than guessing, since an undersized chock lets the tyre roll straight over it.
Are rubber wheel chocks better than plastic ones?
For grip and load capacity, yes, since weight and compound resist sliding on concrete. Plastic chocks run lighter, cheaper and easier to store, and they work fine for lighter loads on level ground. Rubber is the better choice on slopes or smooth concrete.
How many wheel chocks do I need?
A pair at minimum, placed on either side of one wheel or on the downhill side of two wheels. Four chocks make the safer setup for a tandem axle trailer, and an expanding stabiliser between the tyres adds stability on top of that.
Which side of the wheel should a chock go on?
The downhill side on a slope, since that is the direction the vehicle will roll. Chocking both sides of a wheel prevents movement in either direction on level ground. Always push the chock tight against the tyre with no gap.
Do I still need chocks if the parking brake is on?
Yes, for anything left unattended on a gradient or being worked on. Parking brakes act on two wheels only, can fail and can slip on a steep slope. Trailers frequently have no functioning brake at all when unhitched, which makes chocks the primary restraint.
Can wheel chocks be used on gravel or grass?
Yes, and they often work better there than on smooth concrete because the surface itself provides resistance. Check that the chock still bears against the tyre rather than sinking into a rut on soft ground.
Do chocks help while jacking up a vehicle?
They form an essential part of the process, applied to the wheels that stay on the ground to stop the vehicle moving off the jack. They support no weight themselves, so jack stands remain mandatory before anyone goes underneath.
How long do wheel chocks last?
Rubber chocks last many years if stored out of direct sunlight, while plastic chocks left permanently outdoors can turn brittle and crack after a few seasons of ultraviolet exposure. Inspect for cracks and worn ribs before each significant use and replace anything showing damage.
What is the best wheel chock for a tandem axle RV?
Camco X-Chock is built specifically for tandem axles, expanding between the two tyres with a ratchet to remove the side to side rocking that ordinary chocks cannot address. Pair it with conventional chocks for parking on a slope.
The verdict
MAXXHAUL 70075 solid rubber chocks are the sensible buy for most people, since weight and grip are the only two things that genuinely matter once the ground is not perfectly level. RV owners with tandem axles should add the Camco X-Chock to stop the rocking that ordinary chocks cannot address, and Camco Heavy Duty plastic chocks remain a fair choice for light loads where storage space is tight.
