Does the BILSTEIN B4 Air Suspension Strut fit both front corners?

No. This B4 Air Suspension Strut is the front right strut only and is sold individually, one per box. The front left strut is a separate BILSTEIN part. Many owners replace both struts on an axle at once, so the two sides ride alike and the front of the A8 or Phaeton stays level.

Will the front right strut connect to the factory air suspension?

Yes. BILSTEIN supplies air suspension to carmakers as original equipment, and builds the B4 strut to connect directly to the original air line and electrical connector at the front right corner. The front right strut installs without modification, and the factory level control manages it as before.

Which cars does the front right strut fit?

For the front right corner, BILSTEIN lists the 2004 to 2010 Audi A8 L quattro and the 2005 to 2010 A8 quattro, both D3, and the 2004 to 2006 Volkswagen Phaeton V8 and W12, on the standard suspension. The A8 and Phaeton share this front strut because they share their platform and air suspension design.

What are the signs of a failing front air strut on an A8 or Phaeton?

Typical signs are the front right corner sitting low after the car has been parked, a compressor that runs for long periods, a suspension warning in the cluster and a bouncy or harsh ride over bumps. A leaking air spring is the usual cause, and the front right strut is replaced as one assembly.

What warranty comes with the front right strut?

BILSTEIN backs this front right B4 air strut with its Limited Lifetime Warranty, and the strut is made in Germany. Bulletproof Automotive handles any warranty claim with BILSTEIN for the owner, so the front right strut is supported by the same place it was bought.

Description

BILSTEIN B4 Air Suspension Strut for D3 Audi A8 and Volkswagen Phaeton, Front Right

BILSTEIN’s B4 Air Suspension Strut for D3 Audi A8 and Volkswagen Phaeton is the front right air strut for the 2004 to 2010 A8 quattro and A8 L and the 2004 to 2006 Phaeton V8 and W12. When this corner leaks, the car settles overnight and rides poorly over sharp bumps; a new BILSTEIN strut brings back the level stance and quiet ride both cars were engineered for.

Design and Performance

Inside the air spring sits a twintube damper, with a fork lower mount and the vehicle-specific upper mount. The strut uses the original connectors, so no wiring or air-line changes are needed.

About BILSTEIN

BILSTEIN was founded in 1873 by August Bilstein in Altenvoerde, now Ennepetal, Germany, where its engineers are still based. In 1957 it fitted the first monotube gas pressure shock absorber to a Mercedes-Benz series production car, and Audi, BMW, Porsche and Volkswagen are among the carmakers that have used its dampers as original equipment since. BILSTEIN develops its suspension on its own test circuit in Papenburg and on the Nürburgring Nordschleife, and it has been part of thyssenkrupp since 2005.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
