This is the front right (passenger-side) strut from Bilstein's B6 Performance line, built as a monotube gas-pressure unit. The shocks and struts feature a monotube design which provides consistent fade free performance. They use a velocity sensitive, digressive piston that reacts to changing road conditions. Each unit is tuned for each specific application to assure optimal performance is achieved. Search terms that fit this part include BMW F22 228i xDrive front right monotube strut, Bilstein 35-264590, and B6 Performance passenger-side strut upgrade.
Compared with the stock strut, the B6 is positioned as a ride and handling upgrade, and the manufacturer describes a significant improvement in ride quality, handling, and comfort. The B6 Performance series also carries a Limited Lifetime Warranty, which helps justify the price over budget replacements. Because the valving is set for the vehicle rather than as a generic fit, it is a better match for spirited street driving and occasional track days than a cheaper strut that is not tuned to the application.
The fitment listed for this SKU is the 2015–2016 BMW 228i xDrive, and this listing is specific to vehicles without electronic suspension, so verify your car's configuration before ordering. The assembly weighs 11 lbs, which makes it manageable for a home mechanic. The manufacturer notes the B6 is easy to install like any other OE shock absorber thanks to its original design. Shoppers looking for a 228i xDrive without electronic suspension front strut replacement should buy one per side, and plan a wheel alignment afterward.
This listing is for vehicles without electronic suspension. Confirm your car's configuration with the manufacturer's fitment lookup before ordering, because the manufacturer's fitment list for this SKU covers the 2015–2016 228i xDrive.
The manufacturer lists a limited lifetime warranty for the B6 Performance series. Check the manufacturer's warranty terms for coverage details.
The B6 is designed to be swapped in much like the factory strut, so a competent DIY mechanic with standard suspension tools can handle a one-side replacement. Confirm the included hardware and any spring transfer steps against the manufacturer's installation instructions before starting. Have the front alignment checked afterward, since a strut change affects camber and toe.
