This lift kit is more than just a simple lift; it's a complete suspension upgrade engineered with heavy-duty construction and precision geometry. Highlights of this kit include:
OE-style cast iron knuckles with corrected geometry for proper steering and handling.
Laser-cut, CNC-formed crossmembers and full-coverage differential skid plate built from 3/16" steel.
Cast rear lift blocks and taller fabricated torsion arm brackets for a level stance and reliable strength.
Xtreme-Duty 4130 chromoly steel upper control arms with corrected ball joint angles for long-term durability.
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.
The Falcon 3.3 Fast Adjust Performance shocks are built for every job and feature an 8-position micro-adjust dial to fine-tune rebound damping with precision. The Compression Knob has 3 positions to provide soft, custom, or firm ride quality to instantly change ride feel. Reservoir Design of these shocks allows for a high-capacity reservoir to maintain consistent damping across a broad temperature range. For consistent performance at extreme temperatures (-50F to 450F), these Falcon shocks use Red Line High VI Shock Oil. Hard-anodized 6061-T6 Aluminum bodies resist corrosion while the VOD (Volume Optimized Damping) piston technology reduces body roll, enhances control, and curtails bottom-out in extreme conditions.
When it comes to towing, hauling, backcountry exploration, or simply wanting the best HD stance for everyday driving, the ReadyLIFT 6" MAX3.3 offers unparalleled versatility, excellent ride quality, and significant strength.
