Toyota builds some of the highest-volume passenger cars in the world, and the Corolla and Prius lines alone account for tens of millions of vehicles still running across Asia, the Middle East, Africa, Europe, and the Americas. As this vehicle population ages, the elastomer components around the shock absorbers are among the first suspension parts to fail. Bonpora supplies a replacement rear suspension bump stop for Toyota applications under Bonpora No. 4110043, matching OE number 48341-47010, molded in polyurethane with dimensions of Φ18 × Φ52 × 60.4 mm. This page is written for importers, auto parts distributors, and suspension workshops that source by OEM number and need a dependable factory channel for Toyota strut buffers.
The bump stop, which Toyota catalogs as a rear spring bumper, slides onto the piston rod of the rear shock absorber and cushions the final stage of suspension travel before metal can strike metal. When the buffer is cracked, torn, or crushed flat, the damper bottoms out on hard impacts, ride quality deteriorates, and the shock absorber seal and internal components wear faster. Suspension shops therefore replace the bump stop together with the shock absorber or dust cover during rear axle service. Related suspension components can be found in our shock absorber parts catalog.
Buyers who match parts by size or by OE number can check the parameters of Bonpora No. 4110043 in the table below. The outer diameter of 52 mm and the height of 60.4 mm correspond to the original Toyota rear spring bumper fitted across a wide range of Corolla and Prius platforms.

Reference 48341-47010 is cataloged for the rear axle, one buffer per side, and it appears in Toyota parts books for a long list of front-wheel-drive models built from the late 1990s onward. The most important applications for aftermarket demand are summarized below. Always confirm the chassis code of the customer vehicle before quoting, because Toyota used several rear spring bumpers with similar shapes but different heights within the same model family.
The largest application group is the Corolla family. The reference fits the rear suspension of the E120 generation, such as the ZZE122 sedan sold from 2001 to 2007, the Corolla Fielder and Corolla Axio NZE14 and ZRE14 series built from 2006 to 2012, and the E170 generation ZRE172 sold from 2013 to 2019 in Asian and American markets. Catalog listings also cover the Corolla Spacio NZE121, the North American Corolla Matrix ZZE13 series, and platform derivatives such as the OPA ACT10, the Will VS, the Voltz, and the Premio and Allion NZT and ZRT series. Because these nameplates were produced in Japan and assembled or licensed in China, India, South Africa, Brazil, and other markets, replacement volumes for this buffer are high and continuous, and parts distributors in these regions list it among their regular fast-moving suspension items.
The second key application is the Prius hybrid. The buffer fits the rear axle of the first generation NHW11 sold from 2000 to 2003 and the second generation NHW20 sold from 2003 to 2009, two of the most widely traded hybrid vehicles in the global used car market. Catalog listings extend coverage to the Sienta NCP8 and NSP17 compact MPV series and the Vista Ardeo station wagon. Hybrid taxis and ride-hailing fleets accumulate mileage quickly, so rear suspension buffers on NHW20 Prius vehicles are consumed at a steady rate, which makes this reference attractive for stocking distributors serving fleet workshops.
Bonpora molds this buffer in micro-cellular polyurethane rather than conventional rubber. The material structure contains millions of sealed micro-cells, so the part compresses progressively under load and recovers its shape instead of taking a permanent set. For wholesale buyers, polyurethane offers three practical benefits. First, resistance to ozone, heat, and aging is higher than that of typical rubber compounds, which matters in hot climates where underbody temperatures accelerate rubber degradation. Second, density is stable from batch to batch, so the compression curve remains consistent and the vehicle keeps its designed ride behavior. Third, polyurethane keeps a smooth molded surface that resists splitting during installation and storage. Our complete range of molded buffers, including many Toyota, Honda, and European references, is available in the polyurethane bump stops category.
Polyurethane also performs well across temperature extremes. In tropical markets the material stays stable under high underbody temperatures, while in cold climates it remains flexible at low temperatures where some rubber buffers harden and crack. This wide operating window is one reason polyurethane buffers have become a common choice for aftermarket suspension programs in export markets.
Every production batch passes dimensional inspection with calipers and height gauges, hardness checks on the molded body, and compression tests on sample pieces before packing. Sampling follows AQL practice, and inspection records can be shared with customers on request. Buyers who prefer independent verification are welcome to appoint a third-party inspection company, and our team will support the process with samples and factory access. This approach keeps rejection rates low for distributors who resell the buffers under their own brands.
Most professional buyers complete the purchase in four steps: match the OE reference, confirm the drawing, request a quotation, and book production.
Send the OE reference 48341-47010 or the Bonpora number 4110043 to our sales team, ideally together with the chassis code and the required quantity. We confirm the drawing dimensions, quote on FOB or CIF terms, and provide samples for inspection when required. Drawing copies in PDF format and sample photos are available on request before ordering. Buyers who prefer to verify fitment first can cross-check the reference against Toyota parts catalogs, where 48341-47010 is listed as Bumper, Rear Spring for the models described above. Mixed orders that combine this buffer with other bump stops, dust covers, and suspension components are welcome, and shipments can be consolidated to reduce freight cost per piece.
Beyond catalogue items, Bonpora provides OEM and custom design support for polyurethane buffers. If your market requires a different hardness, an adjusted geometry, a reinforced mounting hole, or private brand packaging, we can develop the part from a sample or a drawing. The standard procedure covers mold design, sample confirmation, a dimensional report, and batch production after approval. This service is used by regional suspension brands in the Middle East, Africa, and South America that package buffers under their own labels and need stable mold capacity.
Each bump stop is packed in a poly bag and boxed in neutral export packaging, so the goods can be resold under your own brand without conflict. Standard production time is 15 to 30 days depending on order quantity, and the warranty period is one year under normal service conditions. Cartons are labeled with item numbers and quantities for convenient warehouse handling, and palletized loading is available for container orders. Minimum quantities for mixed container orders are flexible, and the sales team can suggest a balanced assortment of sizes and OE references based on recent demand from similar markets. For urgent replenishment, stock references can usually leave the factory earlier than full production runs, which helps distributors stabilize inventory during peak service seasons.
It is the rear spring bumper for a wide range of Toyota front-wheel-drive models, including the Corolla E120, E140, and E170 generations such as ZZE122, ZRE142, and ZRE172, the Corolla Fielder and Axio NZE14 and ZRE14 series, the Matrix, Premio, Allion, OPA, Spacio, Sienta, and Vista Ardeo, and the Prius NHW11 and NHW20 generations. One buffer is fitted per side on the rear axle.
The buffer measures Φ18 × Φ52 × 60.4 mm. The 18 mm inner hole slides over the damper piston rod, the 52 mm body carries the compression load, and the 60.4 mm height matches the original Toyota part. The material is micro-cellular polyurethane, and each piece is molded with a smooth, closed surface.
Yes. Trial orders and sample requests are accepted so that buyers can check fitment and quality before committing to container quantities. Send the OE number, the destination port, and the estimated annual volume to receive a quotation and sample terms.
Standard delivery time is 15 to 30 days after order confirmation, and the warranty is one year under normal use. Neutral export packaging is included as standard, and OEM packaging can be arranged for private label customers.
