The Timbren TORSEN04 Suspension Enhancement System is designed to improve rear suspension support on 2004-2016 Toyota Sienna models. Using Timbren’s patented Aeon® hollow rubber springs, this system helps control rear-end squat, reduce body roll, and limit sway when carrying passengers, cargo, or towing light loads. The progressive rubber springs engage when additional weight is applied, providing extra support while maintaining a smooth and comfortable ride when the vehicle is unloaded. The rear kit installs with a simple bolt-on design and requires no ongoing maintenance after installation. For long-term durability and reliability, the system is backed by Timbren’s lifetime warranty.
