Product Overview

 

The ReadyLIFT 8" MAX3.3 Suspension System is engineered for 2019–2025 Chevrolet Silverado 1500 and GMC Sierra 1500 4WD trucks seeking premium ride quality, advanced suspension adjustability, and aggressive lifted styling without compromising drivability. Designed around Falcon’s premium 3.3 Fast Adjust dampers, the MAX3.3 system combines heavy-duty geometry correction with advanced suspension tuning capability for highway driving, towing, and off-road performance.

The system also includes heavy-duty DOM tubular upper control arms, boxed steel crossmembers, differential drop brackets, fabricated rear lift blocks, and a full-width skid plate engineered specifically for the GM 1500 platform.

ReadyLIFT engineered the MAX3.3 system to preserve factory ride comfort, steering feel, and turning radius while supporting up to 37x12.50-inch tires on compatible wheel setups. Extensive highway and off-road testing ensure improved suspension control, ride stability, and premium drivability across multiple terrain conditions. Now Available at LEER!
