Why Upgrade?

While Toyota’s factory suspension offers a balanced ride, it’s limited in adjustability and off-road performance once you start modifying tire size, weight, or ride height. The Peak 2.5” DSC Coilover System solves those issues with fully rebuildable, height-adjustable dampers and Dual Speed Compression (DSC) adjusters — allowing you to fine-tune both low- and high-speed compression for the perfect balance of on-road comfort and off-road capability.
