We’ve paired our 4-Link Suspension Kit with a custom QA1 9" rear housing for enthusiasts seeking top-tier performance and hassle-free installation. Your time is valuable, so say goodbye to hunting for junkyard rear ends or struggling with endless measurements and mismatched components. Every piece in this package is tested by QA1 to fit the first time. This kit delivers the performance, ride quality, and adjustability you need to handle serious power and aggressive driving— without the frustration of piecing things together.
Ditch your leaf springs for QA1 MOD Series Coilovers, triangulated 4-link suspension and an all-new 9" rear end. QA1 4-link kits were fully engineered to provide ride height, ride quality and instant center adjustability. Whether you're after a lowered, aggressive look or need clearance for wider wheels and tires, QA1 systems deliver.
QA1 is committed to delivering products that make upgrading your car as simple as possible. The rear crossmember requires minimal, but easy MIG welding. Once in place, the rear end housing is a direct bolt-in.
