Semi trailer rubber bumpers help cushion contact during docking and protect trailer surfaces, loading areas, and nearby equipment. The Buyers Products B5500 is best for buyers who want a two-piece, tall bumper set; DENCO is a strong fit when reinforced mounting holes and weather resistance matter. For buyers who need several compact bumpers, the four-pack options offer a larger quantity, while the two-pack and single-piece A.A. options suit smaller replacement needs.

Buyers Products B5500 Molded Rubber Bumper Set
This two-piece set is best for buyers who need a taller molded bumper for a truck, trailer, loading dock, or delivery bay. Each bumper measures 3 inches wide, 3.5 inches deep, and 6 inches tall. Its compression-molded rubber construction is designed for frequent contact and does not rust or dent like metal.
Choose this option when the 6-inch height fits the mounting area and you want a pair of bumpers for high-impact locations. The listed features emphasize durability in commercial and industrial settings. The product information does not specify mounting-hole dimensions, so confirm how it attaches before ordering.
DENCO Heavy Duty Rubber Trailer Bumpers
DENCO’s pair is best for buyers prioritizing reinforced mounting and exposure to demanding outdoor conditions. The bumpers measure 5.5 by 2.5 by 3 inches and have metal-lined mounting holes spaced 2.5 inches center to center. The listed rubber construction is intended to resist moisture, UV exposure, road debris, and temperature extremes.
Choose this pair if its mounting-hole spacing and dimensions match your trailer or dock. It is described for repeated docking impacts and protection of trailers, docks, and surrounding equipment. A key limitation is its 3-inch height, which may not suit installations that require a taller buffer.
A.A. Reinforced Rubber Dock Bumper, Four-Pack
This four-pack is best for buyers outfitting several contact points or keeping matching replacements available. Each molded rectangular bumper is approximately 6 by 3.25 by 3 inches. The product is described for reducing impact damage at loading docks and on trucks, cargo trailers, and flatbeds.
Each bumper has a 1/2-inch bolt hole, with a 1.25-inch inside-diameter recess that is 2 inches deep. That mounting detail makes this option useful when the installation needs a recessed bolt area. Check bolt size, recess clearance, and mounting location before buying; the listed features do not specify weather-resistance performance.
Lakapre Heavy Duty Dock Buffers, Four-Pack
Lakapre’s four-pack is best for buyers seeking buffers for more than one vehicle or surface. Each block measures 6 by 3 by 3 inches and is described as compression-molded rubber designed to absorb shock during loading, docking, and tight maneuvers. Listed applications include trailers, flatbeds, reefers, boats, and marina docks.
The product features state that the rubber resists cracking, weathering, and deformation. Choose it for versatile use across vehicle and dock settings, provided the block dimensions suit the installation. Its listed features do not provide bolt-hole measurements, so verify the mounting method before purchase.
A.A. Reinforced Rubber Dock Bumper, Two-Pack
This two-pack is best for replacing a pair of bumpers or protecting a smaller number of impact points. Each molded rectangle measures approximately 6 by 3.25 by 3 inches and is described for semi-trucks, trailers, flatbeds, and loading docks.
The mounting details match the A.A. four-pack: a 1/2-inch bolt hole and a recessed area with a 1.25-inch inside diameter and 2-inch depth. Choose this pack when two pieces meet the job requirement; select the four-pack if you need more coverage or spares. Confirm the mounting dimensions against your existing hardware.
Buying Guide: How to Choose Semi Trailer Rubber Bumpers
Which bumper dimensions should I check?
Measure the available mounting area and identify the height, width, and depth the installation can accommodate. The products here range from 3 inches to 6 inches tall, so their profiles are not interchangeable. Also compare the bumper’s contact surface with the area it needs to protect.
How important are mounting details?
Check the hole size, hole spacing, recess dimensions, and required bolt clearance before selecting a bumper. DENCO lists metal-lined holes with 2.5-inch center-to-center spacing. The A.A. bumpers list a 1/2-inch bolt hole and recessed mounting area. Buyers Products and Lakapre do not list mounting measurements in the supplied features.
How many bumpers do I need?
Count the locations that need protection and consider whether you want spare pieces. A pair may suit a two-point replacement, while a four-pack can cover more locations. Pack quantity alone does not determine fit: compare the dimensions and mounting approach of each option.
Are all rubber bumpers suitable for outdoor exposure?
No specific outdoor-resistance claims are listed for every product. DENCO describes resistance to moisture, UV exposure, road debris, and temperature extremes; Lakapre describes resistance to weathering. Review the product details for the intended conditions rather than assuming all rubber compounds perform the same way.
