Upgrade your Toyota Tacoma’s rear suspension with the RAS Suspension Kit—engineered for 2005–2025 models with axle-on-top leaf spring configurations. This bolt-on RoadActive Suspension system strengthens your rear leaf springs, reduces rear-end squat, sway, and bounce, and delivers a smoother, more controlled ride whether towing, hauling, or driving daily.
Unlike air bag systems, RAS is fully mechanical and maintenance-free—no compressors, air lines, leaks, or constant adjustments required. Its progressive design provides extra support under load while maintaining factory-level comfort when unloaded. This 3-in-1 system acts as a helper spring, sway bar, and traction bar—at a fraction of the cost of other upgrades—and installs in approximately one hour.
