Engineered for street and occasional track use, H&R Coil-Overs feature a fully-threaded shock body (not an imitation sleeve-over) that allows you to precisely dial in height adjustment to achieve optimum weight transfer, or simply get the aggressive look you've been looking for. Featuring H&R's exclusive dynamic damper technology, each shock is engineered to work in harmony with a progressive-rate spring, together creating a finely-tuned suspension system. H&R Coilovers are stiffer than most, providing a more aggressive ride and lower drop range for performance-oriented enthusiasts. Need an Installer? The Tire Rack's List of Recommended Installers are a great installation option. You can drop-ship to their location, too! H&R Products ship directly from H&R North America.
