Excel-G Product Line Details

The KYB Excel-G line is built on the same OE assembly lines used for original equipment supply and uses OE-quality components. It is calibrated to return the vehicle to its original designed performance rather than changing the ride character, making it a practical choice for BMW 3 Series front suspension service.

Detailed Description

KYB Excel-G 334615 is engineered as an OE-style replacement for the front left position on select BMW 3 Series models. With a compressed length of 12.63 inches, extended length of 16.79 inches, and 4.16 inches of stroke, this strut is built to match the suspension geometry and control requirements of the listed applications. The 14x1.50 upper mount type supports proper fitment where specified, while the twin-tube gas-charged design helps maintain consistent damping performance.

This part cross-references Monroe Shocks & Struts 71582 for the same application. It is also associated with BMW OE part numbers 31311096855 and 31312282101. For drivers searching for a front left BMW 325Ci strut replacement, a BMW 330i front left strut, or a BMW 328i sport suspension strut, KYB 334615 is built for the listed fitments.

What It Helps Address

• Excessive bounce or reduced damping control
• Loose steering feel during lane changes
• Uneven tire contact from worn suspension damping
• Body movement that affects braking and cornering stability
• Noise or leakage associated with worn strut seals
