Fabtech K1131 Uniball Upper Control Arm Lift System GM - 3 2019-2020 1500

The Fabtech K1131 is a complete 3.5-inch lift system engineered specifically for 2019-2020 GM C/K1500 pickups, including the Sierra Denali. This system delivers increased ride height and enhanced off-road capability while maintaining factory ride quality and preventing suspension bind at full droop.

Uniball Upper Control Arms:

The centerpiece of this system is the heavy-duty uniball upper control arms, constructed from premium .120-inch wall, 1.50-inch OD 4130 chromoly tubing. These UCAs utilize high-quality 1-inch FK stainless steel PTFE-lined uniball bearings in place of traditional ball joints, providing exceptional durability in rugged off-road conditions and a more positive on-road driving feel with improved steering response.

Front Lift Components:

The 3.5-inch front lift is achieved using precision-engineered steel spacers that work with your factory coilover shocks, preserving the stock adaptive damping system and smooth ride characteristics.

Rear Lift Components:

The rear of the vehicle is lifted 1.5 inches using included lift blocks and u-bolts, maintaining compatibility with the factory Adaptive Ride Control shocks for consistent performance front to rear.

Key Features:

• Increased ground clearance for improved off-road capability
• Increased fender clearance accommodates up to 33-inch tall tires
• Superior uniball design offers extended lifespan over ball joint systems
• Retains factory shock absorbers and adaptive suspension systems
• Fully reversible to stock configuration if needed
• Straightforward installation process

This system is ideal for truck owners seeking enhanced off-road performance and aggressive tire fitment while maintaining daily drivability and factory ride control technology.
