2020 Chevrolet Silverado 3500 HD

Product Features

  • Fits 2020-2024 GM HD 2500/3500
  • SST lift-specific Forged Torsion Keys
  • Xtreme-Duty fabricated 4130 chromoly steel upper control arms
  • Front inner fender bracket to fit larger tires
  • Allows for no-trim 20x9 0 offset on a 35x12.50 tire.
  • *Max with trimming: 20x10 -18 offset - 35x12.50. Some fender well trim variances may be experienced between Silverado and Sierra models.
  • Vehicle-specific performance-tuned Falcon 2.1 monotube dampers on all four corners.
  • Improved dynamic roll control and low-speed damping.
  • Dramatic improvement in on-road comfort and off-road performance.
  • Optimized fitment for unobstructed suspension travel and articulation.
  • 6061-T6 aluminum alloy shock body resists Impact to protect internal components.
  • Exceeding this will overlift the vehicle creating a top-off condition, meaning the suspension has little to no down travel. The result is poor ride quality and premature wear of components.

Product Overview

 

The ReadyLIFT 3" SST 2.1 Suspension System is engineered for drivers who want premium ride quality, improved off-road capability, and larger tire clearance without sacrificing daily drivability. Available for platforms including the Toyota 4Runner, Toyota Land Cruiser, Toyota Tacoma, Toyota Tundra, Ram 2500 Diesel, Chevy Colorado, and GM Silverado/Sierra 2500HD & 3500HD, these systems combine ReadyLIFT Smart Suspension Technology with Falcon 2.1 monotube dampers for enhanced comfort and control.

Built around Falcon 2.1 monotube shocks and struts, the SST2.1 systems are designed to deliver improved highway stability, smoother off-road damping, and consistent suspension performance across changing terrain conditions. ReadyLIFT specifically tuned the Falcon 2.1 dampers for each platform to balance comfort, control, and durability for both street and trail use.

Additional features include heavy-duty tubular or fabricated upper control arms, corrected ball joint geometry, skid plates, sway bar relocation components, and application-specific suspension correction hardware. The Toyota 4Runner and Land Cruiser systems include DOM tubular upper control arms with corrected high-angle geometry, while GM HD systems include fabricated heavy-duty control arms designed for towing and oversized wheel/tire combinations.

Depending on application, the ReadyLIFT SST2.1 systems support tire fitments ranging from 33-inch tires on 4Runner and Colorado applications to 35-inch tires on Tacoma, Tundra, Land Cruiser, Ram 2500, and GM HD applications with proper wheel setup and minor trimming where required.

The systems are engineered specifically for each platform using vehicle-specific spring rates, shock valving, and geometry correction components to maintain OEM-style ride quality while significantly improving ground clearance and suspension capability. Installation is designed as a complete bolt-on suspension system with no cutting required on most applications. ReadyLIFT recommends professional installation and alignment after installation.

Whether you're upgrading for overlanding, towing, larger tires, trail capability, or a more aggressive stance, the ReadyLIFT 3" SST 2.1 Suspension System delivers premium suspension performance across a wide range of modern trucks and SUVs. Now Available at LEER!
