Restore rear ride height and factory-style control with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4037, a complete corner unit that combines the strut, mount and spring in one pre-assembled package. It installs as a direct-fit REAR replacement for the 2004-2005 Chevrolet Classic, 1998-2003 Chevrolet Malibu, 1999-2004 Oldsmobile Alero, 1998-1999 Oldsmobile Cutlass, and 1999-2005 Pontiac Grand Am — see the Buyer's Guide tab for engine-specific coverage.

As an original-equipment supplier, KYB engineers the Strut-Plus to help restore your vehicle's handling and control. Because it arrives assembled, no spring compressor is required for installation.

  • OE-Restoring strut: built on a KYB Excel-G strut with a stronger steel outer shell and application-specific, precision-designed damping valves.
  • Application-engineered spring: high-carbon steel coil spring designed to match the strut, help maintain proper ride height and control weight without sacrificing ride quality.
  • Electronic-safety aware: engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
  • Assembled in the USA and designed for proper ride height and original handling capabilities on the listed GM cars.

Sold individually; order two for a complete rear-axle replacement.

Frequently Asked Questions

What comes in this assembly?

It's a complete rear corner unit — the KYB Excel-G strut, the mount, and a high-carbon steel coil spring — pre-assembled into one bolt-in package.

Which vehicles does the SR4037 fit?

The 2004-2005 Chevrolet Classic, 1998-2003 Chevrolet Malibu, 1999-2004 Oldsmobile Alero, 1998-1999 Oldsmobile Cutlass, and 1999-2005 Pontiac Grand Am. Check the Buyer's Guide tab to confirm your vehicle.

Is this a front or rear unit?

This is a REAR strut and coil spring assembly. Confirm the application in the Buyer's Guide tab before ordering.

Do I need a spring compressor to install it?

No. Because the strut, mount, and spring arrive pre-assembled, no spring compressor is required for installation.

Should I replace both sides at once?

It's sold individually, so order two to service the full rear axle. Replacing both sides together helps keep ride height and handling balanced.
