Built for serious truck owners who demand more performance, capability, and confidence - on or off the road. ReadyLIFT is raising the bar once again with the release of our all-new 6” MAX3.3 Premium Suspension Systems for the 2020–2025 Chevy Silverado and GMC Sierra 2500/3500 HD. Engineered from the ground up to deliver the ultimate blend of strength, handling, and ride quality, this system is powered by our vehicle-specific Falcon 3.3 Fast Adjust Piggyback Shocks - the most advanced shocks ever offered in a ReadyLIFT HD system.
With Falcon’s dual-knob adjustability, drivers can fine-tune compression and rebound independently for any terrain or load. From highway cruising to heavy towing to weekend off-road adventures, the MAX3.3 system gives you full control of your truck’s ride and handling characteristics.
Engineered to Perform, Built to Last
This system is more than just a lift; it’s a complete suspension upgrade designed with precision geometry and heavy-duty construction. Highlights include:
Laser-cut, CNC-formed crossmembers and full-coverage differential skid plate built from 3/16” steel.
OE-style cast iron knuckles with corrected geometry for proper steering and handling.
Xtreme-Duty 4130 chromoly steel upper control arms with corrected ball joint angles for long-term durability.
Cast rear lift blocks and taller fabricated torsion arm brackets for a level stance and reliable strength.
The system clears up to 37x12.50 tires on 20x9 wheels (0 offset) giving your GM HD truck the aggressive stance and capability it deserves without sacrificing drivability.
