2019–2024 CHEVY SILVERADO & GMC SIERRA 1500 4WD – MAX3.3 8" SUSPENSION SYSTEM

ReadyLIFT proudly introduces the next evolution in full-size truck performance — the all-new MAX3.3 8" Suspension System, now available for 2019–2024 Chevy Silverado and GMC Sierra 1500 4WD trucks. Engineered for GM enthusiasts who demand top-tier ride quality, aggressive stance, and premium off-road capability, this system is built around the all-new Falcon 3.3 Fast Adjust Front Remote Reservoir Coilovers and Rear Piggyback Shocks — delivering comfort, control, and custom tuning at your fingertips.

Thousands of miles of testing on highways, trails, and everything in between prove this isn't just a lift kit — it's a complete performance upgrade. From the 6061-T6 aluminum shock architecture to the heavy-duty DOM tubular steel upper control arms with proprietary high-angle ball joints, every component is engineered to outperform generic lift kits. Boxed steel front and rear crossmembers, a full-width 3/16" x 8" front skid plate, 1/4" boxed plate steel differential drop brackets with double gussets, and 5" fabricated rear lift blocks with integrated bump stop landings round out one of the most robust 8" systems on the market.

The result? A GM 1500 that drives better than stock — with the aggressive stance and 37" tire clearance to match.

Key Highlights:

  • 8" of lift with a purpose-built, balanced stance
  • Falcon 3.3 Fast Adjust remote reservoir front coilovers included
  • Falcon 3.3 rear piggyback shocks with 8-position micro tuning
  • 3-position Fast Adjust Knob (Soft / Custom / Firm) for on-the-fly tuning
  • Heavy-duty DOM tubular steel Upper Control Arms with high-angle ball joints
  • Boxed steel front and rear crossmembers

  • Factory ride quality and turning radius retained

Get ready to elevate, tune, and dominate — the ReadyLIFT MAX3.3 is the ultimate suspension system for your GM 1500.
