Features
Upgrade your Toyota Tundra’s towing and hauling performance with the RAS HD Suspension Kit—engineered specifically for 1999–2021 models. Designed to improve rear suspension strength and control, this RoadActive Suspension system enhances stability, reduces squat, and delivers a smoother, more confident ride whether your truck is loaded or unloaded.
Unlike air bag systems, RAS is a fully mechanical, maintenance-free solution. There are no compressors, air lines, leaks, or ongoing adjustments required. Its progressive design automatically increases support as load increases, helping maintain proper ride height and improved handling when towing an RV, hauling equipment, or handling daily workloads.
Built as a 3-in-1 solution, it combines the benefits of a helper spring, sway control, and traction support—delivering performance without sacrificing comfort. Fully assembled and ready for bolt-on installation, this kit provides fast results you can feel.
Key Features:
• Fits 1999–2021 Toyota Tundra models
• Strengthens rear leaf springs by up to 50%
• 3-in-1 system: helper spring, sway control, and traction support
• Reduces rear squat, body roll, axle wrap, and bounce
• Progressive load response for towing and hauling
• Maintenance-free design—no air lines or readjustments
• Fully assembled for quick bolt-on installation (~45–60 minutes)
• Proven RoadActive Suspension performance since 1998
