A solid, no-nonsense wheel chock built for RV owners who are serious about keeping their rig parked where they put it. Whether you are unhitching a travel trailer on a sloped driveway or staging a fifth wheel on a gravel site, this dense rubber block gives you the grip and mass to stop unintended roll. At 3.85 lbs with a low-profile 8 x 6 x 4 inch footprint, it is heavy enough to stay in place and small enough to toss in a storage compartment without taking over the space.
Wheel chocks are one of those items that feel optional right up until the moment they are not. Tongue jacks and hitch couplers are not designed to hold a rolling trailer -- they are alignment tools, not brakes. A properly placed rubber chock behind and in front of a tire is the last line of defense between a parked rig and an expensive problem.
Lippert built this chock from solid, dense rubber that conforms slightly to uneven surfaces -- pavement, packed gravel, grass, and concrete all give it a purchase. The wedge profile locks under the tire and resists kick-out under load. Unlike lightweight plastic chocks that can crack in cold weather or skitter across smooth concrete, this rubber unit stays put.
Dense rubber body resists cracking, crushing, and UV degradation across a wide temperature range. No hollow core to collapse under load.
The 4-inch height and tapered wedge profile slides easily under tires and locks in place as the tire settles against it.
Textured rubber base grips pavement, concrete, gravel, and grass -- the surfaces you actually encounter at campgrounds and job sites.
At 8 x 6 x 4 inches and 3.85 lbs, this chock stores flat in a bumper, basement compartment, or tow vehicle bed without wasted space.
This chock is sized for the broad range of RV and trailer applications -- travel trailers, fifth wheels, toy haulers, boat trailers, horse trailers, and utility trailers. The 6-inch width accommodates standard trailer tires from ST175 to ST235 range and most passenger car and light truck tires used on tow vehicles. Use two chocks per axle (one on each side of the tire) for maximum security on uneven or sloped ground.
For maximum security on sloped terrain, place one chock on the downhill side and one on the uphill side of the same tire. This prevents roll in either direction if the trailer shifts during leveling or if weight distribution changes while loading or unloading.
Lippert Components is one of the largest OEM and aftermarket suppliers for the RV industry, producing everything from axles and slide systems to leveling gear and accessories. Their wheel chock lineup ranges from basic X-chock interlocking scissor chocks (used between dual tires) to heavy-duty rubber blocks like this one. Part number 2024121202 is a standalone solid rubber chock -- not an interlocking scissor style. It works independently and does not require a paired chock on the opposite tire to function, though pairing is always recommended for maximum stability.
Plastic chocks are lighter and often cheaper, but they can crack in sub-freezing temperatures and slide on smooth surfaces without textured mats. Rubber chocks like this Lippert unit stay flexible in cold weather and grip most surfaces without added friction mats. If you camp year-round or in variable climates, rubber is the more reliable long-term choice.
Stabilizer jacks reduce sway and bounce -- they do not prevent a trailer from rolling. Always chock the tires independently of the jack system, especially on any site with even a slight grade.
Rinse with fresh water periodically to remove road salt, oil, and grit that can degrade rubber over time. Store out of direct sunlight when not in use to extend service life. Inspect for cracking or permanent deformation before each trip -- a compromised chock should be replaced rather than trusted.
