It is compatible with 2005-2010 Chevrolet Cobalt, 2006-2011 Chevrolet HHR, 2007-2009 Pontiac G5, 2010 Pontiac G5, 2008-2009 Saturn Astra, and 2005-2006 Pontiac Pursuit in the rear position.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced damping control from worn shock absorbers
• Rear-end instability over uneven pavement
• Suspension noise related to degraded shock performance
• Uneven ride quality caused by aging rear shocks

Installation Notes and Tips

Verify rear fitment by year, make, model, and position before installation. Compare the compressed length, extended length, and travel length to the removed part to confirm proper suspension geometry. Inspect surrounding rear suspension components for wear, including mounts and bushings, so the new shock absorber can operate correctly after installation.

Unity 251030 is part of that suspension-focused catalog and is built to support consistent rear damping performance for the listed applications.
