For semi-truck and trailer protection during backing, docking, and repeated contact, molded rubber bumpers are a practical choice. The Buyers Products B5500 is best for a larger 3-by-3.5-inch buffer, while the four-pack reinforced dock bumper is best when multiple mounting points need protection. The B5540 suits tighter spaces, and the B5760 offers a taller, narrower profile. The Peterbilt hood bumper is a model-specific replacement part, not a dock bumper.

Buyers Products B5500 Molded Rubber Bumpers
The B5500 is a general-purpose molded rubber bumper set for trucks, trailers, loading docks, and delivery bays. Each bumper measures 3 inches wide, 3.5 inches deep, and 6 inches tall, and the set contains two.
Its compression-molded rubber construction is designed for repeated contact and does not rust or dent like metal. This makes it a strong fit for commercial fleets or operators who need a durable buffer during tight maneuvering and docking. Choose this model if its relatively broad profile fits the mounting area. Its listed size may be too large for narrow installation spaces, so measure first.
Four-Pack Reinforced Rubber Dock Bumpers
This four-pack is intended to help prevent impact damage at loading docks and on the rear of trucks, cargo trailers, and flatbeds. Each bumper is approximately 6 x 3.25 x 3 inches. The mounting design includes a half-inch bolt hole and a recessed area described as 1.25 inches in diameter and 2 inches deep.
It is best for buyers who need several bumpers for one vehicle or installation and want a recessed bolt arrangement. The pack quantity is a practical distinction from the two-piece options above. Confirm that the mounting surface and bolt dimensions match your setup; the supplied product details do not specify mounting hardware.
Buyers Products B5540 Compact Rubber Bumpers
The B5540 set includes two compression-molded rubber bumpers, each measuring 2-9/16 inches wide, 3 inches deep, and 6 inches tall. It is designed for truck, trailer, dock, and delivery-bay use where repeated contact can cause wear.
This is best for buyers who want a compact-width alternative to the B5500 while retaining a 6-inch height. The rubber construction is intended to resist impact without rusting or denting. Choose it when the listed dimensions fit the available space; avoid assuming it will protect a specific vehicle location without checking the mounting pattern and clearance.
Peterbilt Polyurethane Hood Bumper
This product is a hood bumper pad or bushing rather than a large exterior dock bumper. The listing identifies Peterbilt 330, 357, 377, 379, and 385 models and gives OEM part number 13-03510, with Energy Suspension 30.4005 also listed as an alternative reference.
It is best for an owner or repair professional seeking a model-specific hood bumper replacement and verifying the part number before purchase. The listing describes polyurethane construction and a blue finish. Its narrower replacement-part purpose means it is not the right choice for protecting a trailer rear or loading dock; confirm the truck model and part reference carefully.
Buyers Products B5760 Tall Rubber Bumpers
The B5760 is a two-piece compression-molded rubber set for trucks, trailers, loading docks, and delivery bays. The product name gives dimensions of 2 x 2-1/4 x 7-3/4 inches, while the feature text lists each bumper as 2-1/4 inches wide, 2 inches deep, and 7-3/4 inches tall.
This is best for buyers who need a taller, narrower bumper profile for a tight area. It is designed for frequent contact during loading, backing, or docking. Because the listed width and depth order differs between the name and feature description, verify the exact dimensions with the seller before ordering.
Buying Guide: How to Choose a Semi-Truck Bumper
What type of protection do you need?
Start by distinguishing between a dock or impact bumper and a vehicle-specific hood bumper. Molded rubber blocks are intended to buffer contact at truck, trailer, or dock locations. The Peterbilt part is a replacement hood component, so it should be considered only when its listed fitment and part reference match the repair.
Which dimensions and mounting details matter?
Measure the available width, depth, and height, then check clearance around the mounting location. Compare those measurements with the product dimensions rather than relying on a general “heavy-duty” description. For bolt-mounted products, verify hole size, recess depth, bolt access, and mounting-surface requirements. The four-pack listing supplies hole details; the other product descriptions do not specify their mounting hardware.
Should you choose a two-pack or four-pack?
A two-pack may suit a replacement or a pair of contact points. The four-pack can be more suitable when several positions need bumpers. Pack size alone does not indicate that a product will fit a particular truck, trailer, or dock, so check both the quantity and the intended installation location.
Is molded rubber the right material?
The listed molded rubber products are designed for frequent impact and are described as resistant to rust and denting. Their suitability still depends on the amount of clearance, contact pattern, and mounting strength at the installation point. Match the bumper to the job rather than treating these products as interchangeable with full-width truck bumpers.
Frequently Asked Questions
Are these full-width semi-truck replacement bumpers?
No. Most products listed here are compact rubber impact or dock bumpers. The Peterbilt item is a hood bumper replacement. Check the product type and dimensions before treating any of them as a full-width bumper.
Which option is best for repeated dock contact?
The B5500, B5540, B5760, and four-pack are all described for repeated impact or truck, trailer, and dock protection. Select among them by comparing dimensions, quantity, and mounting requirements.
Which product is specific to Peterbilt trucks?
The polyurethane hood bumper listing names Peterbilt models 330, 357, 377, 379, and 385. Verify the model and part number before ordering.
Do the rubber bumpers include mounting bolts?
The provided descriptions do not confirm whether bolts are included. The four-pack specifies a bolt hole and recessed mounting area, but buyers should verify hardware requirements separately.
