Key Cone Rear Spring Upper Isolators (Metal-tech 4x4 exclusive) sold in pairs

Key Cones

Dual Rate high-performance polyurethane upper spring cones for rear mount applications. Toyota calls these “Secondary Springs" (commonly mistakenly called isolators by some). Key Cones were developed by Metal-tech 4x4 and Energy Suspension over a 3yr collaboration. This dual rate secondary spring is featuring Energy Suspensions proprietary polyurethane in two different durometers. The top accordion tip is soft when engaged and the lower body is firmer as your suspension nears the end of travel. Far superior to the single rate basic rubber found in the OEM application. Key Cones unlock hidden performance on your truck.

100% designed, engineered, tested, and made in the USA.   **Patent Pending**
