ReadyLIFT 8" MAX3.3 Suspension System (42-39841) for 2019-2024 Silverado and Sierra 1500 4WD
The 42-39841 is one of two 8" MAX3.3 listings for 2019-2024 Chevy Silverado and GMC Sierra 1500 4WD trucks, alongside the 42-39840. It uses Falcon 3.3 front remote reservoir coilovers and rear piggyback shocks with a 3-position Fast Adjust knob. See lift kits.
DOM tubular steel upper control arms use high-angle proprietary ball joints. Boxed crossmembers, a full-width skid plate and 1/4" boxed differential drop brackets handle the structure, and 5" rear blocks carry integrated bump stop landings. The listing also mentions a coil spring compressor adjuster. Shop GMC Sierra parts.
2019-2024 Chevy Silverado and GMC Sierra 1500 4WD. On an AT4 or Trail Boss you net 6" over factory height. On an AT4X or ZR2 you net 6" and lose the Multimatic shocks. Not for diesel or Denali models, Adaptive Ride Control, rear mono-leaf springs or Super Cruise. Email support@nvmos.com with your year and trim if you are unsure between the 42-39841 and 42-39840.
