Product Overview
The ReadyLIFT 3.5" SST 2.1 Suspension System is engineered for truck owners who want premium suspension performance, larger tire clearance, and improved off-road capability while maintaining factory ride quality and drivability. Available for applications including the 2015–2025 Ford F-150, 2019–2025 Ram 1500, and 2015–2022 Chevy Colorado/GMC Canyon, these premium SST2.1 systems combine ReadyLIFT Smart Suspension Technology with Falcon 2.1 dampers to create a refined suspension upgrade for both highway and off-road use.
The systems are built around Falcon 2.1 monotube struts and rear shocks, engineered specifically for each truck platform to improve ride comfort, suspension stability, and damping control. The rear Falcon shocks feature 3-position Fast Adjust tuning, allowing drivers to switch between daily driving, sport driving, or tow/haul settings depending on vehicle load and terrain conditions.
Additional features include heavy-duty DOM tubular steel upper control arms with corrected high-angle ball joints, differential drop components, rear lift blocks, sway bar relocation brackets, and geometry correction hardware engineered to maintain suspension performance after lifting. ReadyLIFT designed these systems to improve articulation and durability while maintaining OEM-style steering and ride characteristics.
The F-150 SST2.1 systems provide approximately 3.5 inches of front lift and 2–2.5 inches of rear lift, while the Ram 1500 and Colorado/Canyon systems use platform-specific rear block and spacer configurations to maintain proper rake and towing stability. Depending on application, ReadyLIFT states these systems support up to 35x12.50 tires with appropriate wheel offsets and minor trimming where required.
Engineered specifically for modern half-ton and midsize truck platforms, the ReadyLIFT 3.5" SST 2.1 Suspension System delivers premium ride quality, improved off-road capability, and aggressive styling while maintaining everyday drivability and towing comfort.
Installation is designed as a complete bolt-on suspension system using application-specific hardware and geometry correction components. ReadyLIFT recommends professional installation and alignment after installation.
Whether you're upgrading for larger tires, towing performance, overlanding, trail capability, or a more aggressive truck stance, the ReadyLIFT 3.5" SST 2.1 Suspension System delivers premium suspension performance for modern truck platforms. Now Available at LEER!
