In a push to provide unparalleled ride quality and vehicle dynamics for everything from high-speed desert running to off the grid expedition, the RXT Rear Suspension System was born. The RXT Rear Suspension System is a combination of an all-new ICON multi-rate leaf spring, a hydraulic rear bump stop kit, and three RXT-specific 2.5 Aluminum Series rear shock options. Installation of this system replaces the aforementioned “limiting factors” and completely redefines the potential of the 2007-2021 Toyota Tundra with a 20% increase in wheel travel and the ability to adjust the leaf spring rate to compensate for varying vehicle setups.\u003c\/p\u003e\n\u003cp\u003eRecommended Aftermarket Tires: 35\" x 12.50\" (Larger tires may fit but fender trimming and modifications will be required.)\u003c\/p\u003e\n\u003cp\u003eAPPLICATION NOTE #17: THESE ARE STAND-ALONE KITS AND ARE NOT TO BE USED IN CONJUNCTION WITH ANY OTHER AFTERMARKET KITS\u003c\/p\u003e\n\u003cp\u003eAPPLICATION NOTE #55: SHOCKS ARE FULLY SERVICEABLE.
