If your ride is feeling bumpy or unstable, it might be time for new struts. This AutoShack set includes four complete strut assemblies (front and rear) that come pre-assembled with everything you need: strut, coil spring, mount, boot, bumper, and isolator. Designed as a direct fit for 2005-2009 Buick Allure/LaCrosse and 2004-2005 Chevrolet Impala with 3.4L, 3.6L, or 3.8L V6 FWD engines. They're built to resist corrosion and maintain proper alignment for better handling and a smoother ride. Made to ISO/IATF 16949 standards, these are quality replacements that restore your suspension's performance. Professional installation is recommended, and hardware isn't included, so check what you need beforehand. Use Amazon's 'Confirm Fit' tool to double-check compatibility for your specific vehicle. Backed by a 6-month warranty, this set helps you get back on the road with confidence and comfort.
