Detailed Product Information

This rear suspension strut assembly is engineered for vehicles that need a complete replacement unit rather than individual suspension components. The assembly is designed around the fitment requirements of the Pontiac Grand Am, Chevrolet Malibu, Oldsmobile Alero, Oldsmobile Cutlass, and Chevrolet Classic, with coverage spanning 1998-2005 depending on model. For shoppers searching for a rear strut assembly for 2003 Pontiac Grand Am, rear strut replacement for 1999-2003 Chevrolet Malibu, or a complete rear suspension strut for 1999-2004 Oldsmobile Alero, Unity 15130 matches those applications directly.

Unity positions this line as an OEM-spec aftermarket suspension solution, and the brand’s focus is on consistent fit and dependable replacement performance. This part cross-references Monroe Shocks & Struts (e.g., 181686) for the same application.

Common Problems This Part Can Address

• Rear suspension noise from a worn strut assembly
• Reduced ride control or unstable handling over bumps
• Uneven rear suspension response caused by aging components
• Time-consuming repairs when the original strut, spring, and mount are replaced separately
• Loss of original ride height or damping performance on the rear suspension

Installation Notes

Verify rear fitment by year, make, and model before ordering. This assembly is listed for the rear position only, with a 1998 Chevrolet Malibu application requiring the 2nd design and 2.375" spacing between mounting bolts. Because the unit is fully assembled, installation is streamlined compared with rebuilding a strut, but final alignment checks are recommended after suspension service.
