The strut bump stop on a Honda rear axle is a small polyurethane cushion fitted over the shock absorber rod inside the rear spring seat area: it compresses when the rear suspension reaches full compression and prevents a hard metal-to-metal contact between the shock rod, the upper mount, and the axle bracket. This page presents the Strut Bump Stop with OE reference 52722-SS0-003 and Bonpora No. 4110217, a polyurethane rear jounce bumper produced in China for Honda applications such as the CR-V (RD1 generation, 1996-2001) and the Prelude (1992-1994). The sections below cover the working principle, the dimensions and material of this reference, sourcing by OEM number, wholesale supply from a Chinese auto parts factory, custom manufacturing support, and fitting notes for workshops, importers, and parts distributors searching for Honda bump stop replacement parts.
In normal driving the coil spring carries the vehicle weight and the shock absorber controls how quickly the body moves. When the rear axle drops into a deep pothole or takes a sharp expansion joint at speed, the remaining travel of the suspension is used up almost instantly. At that moment the bump stop is compressed between the shock rod and its upper seat. Polyurethane compresses along a progressive curve, so the part behaves like a secondary spring: the response is soft at first contact and grows steadily firmer as compression increases. This staged absorption takes the final phase of the impact and protects the shock rod, the upper mount, and the surrounding axle structure from a hard bottom-out.
Honda fitted this type of rear stop on models such as the CR-V RD1 generation and the Prelude of the early 1990s, and on both cars the part is loaded every time the rear suspension works through rough roads or carries a full load. CR-V owners often carry luggage, tow, or travel on unsealed roads, so the rear stop works hard; Prelude owners may run lowered or stiffened setups that reduce clearance further. Once the buffer is worn, cracked, or crushed flat, the shock reaches the end of its stroke with no cushion. Drivers notice a sharp knock over speed bumps, a harsher ride at the rear, and extra noise from the rear axle. For workshops the stop is one of the lowest-cost parts to renew while the shock is already removed, and for distributors it is a fast-moving wear item with steady repeat demand in export markets.
The reference 52722-SS0-003 sits in the 52722 numbering family that Honda uses for rear bump stoppers, and catalogue listings for this number cover the Honda CR-V RD1 (1996-2001) and the Honda Prelude (1992-1994), with additional related Honda applications depending on market. The part mounts on the rear shock absorber in the lower insulator position, one piece per side, and it is often supplied together with the shock assembly at the factory. Before ordering, confirm the exact application by model, chassis code, model year, and market, or measure the bore, outer profile, and free length against the removed original part. Sending the VIN or chassis number to the supplier removes nearly all ambiguity before a quotation is prepared.

The size listing Φ12 x Φ44 x 87 mm describes a slim-format stop: a 12 mm centre bore that slides over the rear shock rod, an outer diameter of about 44 mm, and a free length of 87 mm. The free length sets the point at which the stop begins to work inside the suspension, while the bore must match the rod or the dust cover core over which the stop slides. A stop that is too long preloads the suspension and can alter ride height and handling; one that is too short lets the shock bottom out early and passes the impact straight into the body. Because Honda revised suspension details across the production life of the RD1 CR-V and the Prelude, measuring the removed original part before ordering remains the safest practice, particularly for workshops that service several model years.
Polyurethane is selected ahead of ordinary rubber for this product family because it resists oil, ozone, road salt, and repeated compression cycles far better. It holds its shape under sustained load, which matters on a working SUV such as the CR-V, and it stays consistent in hot and humid climates where rubber buffers tend to harden and crumble early. For distributors, the longer service life of polyurethane also means fewer warranty claims from end customers and more stable repeat business on the same part number.
Sourcing by OEM number is the most reliable route when the original part is still legible. The number 52722-SS0-003 identifies this rear bump stop in Honda parts listings, and it maps to a single Bonpora No. 4110217, so distributors and repeat buyers can reorder one specification without checking drawings every time. For mixed orders that span several product groups, the auto parts catalogue organises references by system and by vehicle model, which shortens the quotation workflow considerably.
If the OE number has worn away, identify the part by vehicle data instead: brand, model, chassis code, model year, axle position, and shock design. A photograph of the removed part beside a ruler, together with the VIN, lets the supplier confirm the match before shipment. Workshops that service CR-V and Prelude models across several model years can consolidate their bump stop stock under Bonpora numbers, keeping one part code per application and simplifying reordering across the entire customer base.
This bump stop is manufactured in China for wholesale distribution. It runs as a catalogue item, which means the tooling already exists, dimensions stay stable between production batches, and pricing is structured for carton, pallet, and container quantities rather than single-piece retail. Typical buyers include importers of suspension and rubber components, national and regional distributors serving export markets, fleet maintenance operators, and online sellers who need a dependable source for Honda fast movers. The suspension and rubber parts range from the same production site covers companion items that are usually ordered together, such as strut mounts and dust boots, so a container can be built around complete repair kits instead of single references.
Orders ship in neutral export packaging by default, so goods arrive ready for relabelling under the own brand of the distributor. Delivery time is 15 to 30 days depending on order volume and production scheduling, and the warranty period is 1 year. For first-time customers, sample quantities can be arranged before a bulk commitment, so fitment can be verified on real vehicles before the container is booked.
Each production batch is checked for free length, outer profile, and material hardness. Visual inspection covers flash, voids, and surface defects that could lead to early cracking in service. Dimensional records are kept per batch, so repeat orders match the approved sample rather than drifting over time. This batch-level traceability is one of the reasons the part can be offered with a 1-year warranty for export markets.
Beyond the catalogue part, the same production line supports OEM and custom design work. Available options include tailored polyurethane hardness, adjusted free length or outer profile, coloured material for brand recognition, branded packaging, and private-label marking. Distributors serving a defined vehicle parc often combine several suspension items in one shipment to reduce the freight cost per unit. For a custom project, send a drawing or a physical sample together with the expected annual volume. Tooling and sampling lead times are quoted separately from mass production, and a first-article sample is normally supplied for fitment confirmation before the production run starts.
Replace rear bump stops in pairs, one per side of the axle, and inspect the dust boot, the upper mount, and the spring seat at the same time. A collapsed or crumbling stop usually indicates that the shock has been bottoming out, so check the shock absorber for oil loss before refitting the assembly. On the CR-V RD1 and the Prelude the stop sits directly in the load path of the rear suspension, so torque the upper fasteners to the figure given by the vehicle maker and confirm that the stop is fully seated on the rod before the wheel goes back on.
A polyurethane stop should seat flat on the rod shoulder or the dust cover core. If it does not sit flat, it will wear unevenly and may generate noise within a short mileage. Because the buffer works behind the dust boot, a light coating of the grease specified by the vehicle maker makes future removal easier and reduces the chance of squeaking.
Catalogue listings for 52722-SS0-003 cover the Honda CR-V RD1 generation (1996-2001) and the Honda Prelude (1992-1994) at the rear axle, in the lower insulator position on the rear shock absorber, with additional related Honda applications depending on market. Exact fitment depends on model, chassis code, model year, and market, so confirm the application in the parts catalogue or send the VIN for a precise match before ordering.
Typical signs are a hard knock over speed bumps, a harsher ride at the rear, and visible cracking, crumbling, or permanent compression of the old stop. Because the stop sits on the shock rod behind the dust boot, it should be inspected whenever a rear shock is removed. If the shock has been bottoming out, check the damper for oil seepage at the same time, since a failed buffer often shortens damper life.
Yes. OEM and custom design support is available, including adjusted polyurethane hardness, modified bore, free length, or outer profile, coloured material, and private-label packaging. Send a drawing or a sample together with the target annual volume to receive a quotation and a sampling schedule.
Delivery time is typically 15 to 30 days depending on quantity. Packaging is neutral export packaging by default, with branded options available on request, and the warranty period is 1 year. Sample quantities and mixed-container loading with other suspension parts can be arranged for new customers.
Send the OEM number 52722-SS0-003, the Bonpora number 4110217, the quantity, and the destination port, and the sales team will confirm specification, packing, and delivery schedule. Buyers comparing several sources can review the full auto parts line, which covers suspension, steering, and engine components from the same factory under one catalogue.
