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

No. This B4 Air Suspension Strut is the front left strut only and is sold individually, one per box. The front right strut is a separate BILSTEIN part, and owners replacing both sides need one of each. Doing the pair together keeps the front of the vehicle level and the two sides riding alike.

Will the front left strut connect to the AIRMATIC system?

Yes. BILSTEIN builds the B4 strut to connect directly to the original air and electrical connectors at the front left corner, so it installs without modification and the factory air suspension controller manages it exactly as it managed the original strut.

Which vehicles does the front left strut fit?

BILSTEIN lists the W166 ML250, ML350, ML400 and ML550 from 2012 to 2015, the W166 GLE300d, GLE400, GLE550 and GLE550e from 2016 to 2019 and the X166 GLS550 from 2017 to 2019, all with air suspension. Check the exact model year against the Applications list before ordering.

What does a failing front left air strut feel like?

The front left corner sits low after the vehicle has been parked, the air compressor runs longer than it should, a suspension message appears on the dash and the ride turns harsh or bouncy over bumps. A leaking air spring is the usual cause, and the front left strut is replaced as one assembly.

What warranty comes with the front left strut?

BILSTEIN covers this front left B4 air strut with its Limited Lifetime Warranty, and the strut is made in Germany. Bulletproof Automotive handles any claim with BILSTEIN for the owner, so the front left strut for the W166 or X166 is supported by the place it was bought.

Description

BILSTEIN B4 Air Suspension Strut for W166 Mercedes-Benz ML / GLE and X166 GLS, Front Left

BILSTEIN’s B4 Air Suspension Strut for W166 Mercedes-Benz ML / GLE and X166 GLS replaces the front left air strut on vehicles built with the factory air suspension, from the 2012 ML350 to the 2019 GLS550. A sagging front corner on a large SUV upsets its stance and its ride; this BILSTEIN strut, built to original-equipment standards, puts the vehicle back on an even keel.

Design and Performance

The strut combines the air spring and a monotube damper in one assembly, with a fork-type lower mount and the vehicle-specific upper mount, and it uses the original connectors.

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.
