This 1.5″ lift system for the 2019–24 Chevy Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 4WD is engineered for owners who want additional ride height and proper clearance for full-size 33/12.50R18 or 33/12.50R20 tires. Since these models come with a factory 2″ lift, the added 1.5″ from this kit brings the vehicle to the same overall height as a standard model running a 3.5″ lift—allowing smooth fitment of 33″ tall tires without compromising drivability.
This premium lift package features Fabtech’s legendary stainless steel Dirt Logic 2.5 Coilovers. Built from the highest-grade materials, including a stainless steel shock body and a NitroSteel® piston rod, these Coilovers offer unmatched corrosion resistance and durability. They deliver exceptional ride quality both on and off road, making them ideal for drivers who demand maximum performance.
Fabtech’s tubular Upper Control Arms with heavy-duty ball joints correct the suspension geometry for the new ride height, ensuring proper alignment capability and stable handling. Thanks to GM’s updated suspension design, no differential drop brackets are required for proper CV axle angles, helping maintain factory-like reliability and reducing installation complexity.
Rear lift comes from 1″ blocks and U-bolts, though owners seeking a level stance may choose to leave the rear blocks uninstalled. To complement the front Coilovers, the rear suspension utilizes Fabtech’s legendary Dirt Logic 2.25 shocks—constructed with a stainless steel body and NitroSteel® piston rod for maximum corrosion resistance, long life, and superior damping performance in all conditions.
