Product Details

The KYB Excel-G line is focused on restoring original suspension performance rather than altering it. For BMW X1 front left applications, part number 3358004 is calibrated to support proper ride control, lane-change response, and braking stability while working with the vehicle’s suspension geometry as intended. KYB also notes that electronic safety systems depend on suspension, brakes, and tires operating to manufacturer specifications, making correct strut performance important to overall vehicle behavior.

This part cross-references BMW 31316851335 and 31316851339 for the same application.

What This Strut Helps Address

• Excessive front-end bounce or float
