Excel-G Product Line Details

KYB Excel-G is built on the same OE assembly lines KYB uses for original equipment supply and uses OE-quality components calibrated to return the vehicle to its original damping characteristics rather than change them. For Buick Regal owners, that means a replacement strut focused on factory-style ride control and predictable suspension response.

Detailed Description

KYB part number 339375 is an OE-style suspension strut for the front right position on the Buick Regal. It measures 13.93 inches compressed, 19.44 inches extended, and 5.51 inches of stroke, with an upper mount type of 14X1.50. This Excel-G strut is engineered to help maintain proper tire contact and steering response while supporting stable body motion during braking and lane changes. This part cross-references Monroe Shocks & Struts (e.g., 72183) for the same application.

What It Helps Address

• Excessive bounce or float from a worn front strut
• Reduced steering response on the Buick Regal
• Uneven tire contact caused by weak damping control
• Noise or vibration from suspension wear when paired with aged mounts
• Loss of alignment stability from flex in the strut assembly
