The Cognito Motorsports 6-Inch Performance Lift Kit delivers a complete suspension upgrade for 2007-2018 Silverado/Sierra 1500 trucks in both 2WD and 4WD configurations with OEM cast steel control arms. Engineered, manufactured, and assembled in the USA, this comprehensive kit combines precision-engineered Cognito components with premium Fox Performance Series shocks for superior ride quality and corrected geometry.
SM Series Ball Joint Upper Control Arms:
The included SM Series upper control arms feature boxed sheet metal construction with CNC robot welding for exceptional strength and durability. These arms correct ball joint angles specifically for lifted applications, improving droop travel for enhanced ride quality. Finished in semi-gloss black powder coating, each arm comes complete with ball joints, new crush sleeves, and polyurethane bushings.
Fox 2.0 Performance Series IFP Shocks:
Fox 2.0 Performance Series shocks deliver exceptional on-road comfort and predictable off-road handling. The IFP (Internal Floating Piston) design eliminates oil aeration for consistent performance, while the metal impact extruded aluminum body increases cooling capacity and resists corrosion. Factory-tuned precision valving ensures optimal damping in all conditions.
Rear Block Kit:
The 4-inch cast steel blocks are powder coated semi-gloss black and paired with heavy-duty zinc-plated U-bolts to level the vehicle front to rear while maintaining proper suspension geometry.
Kit Includes:
- 6-inch front lift components with corrected CV joint angles
- SM Series ball joint upper control arms with hardware
- 4-inch rear block and U-bolt kit
- Fox 2.0 Performance Series IFP coilovers (front)
- Fox 2.0 Performance Series IFP shocks (rear)
Performance Features:
- Maintains adequate droop travel for superior ride quality
- Levels vehicle front to rear for improved stance
- Accommodates up to 33x12.5 tires on 10-inch wide wheels with 4.75-inch backspacing
- Corrected geometry prevents premature CV joint wear
Installation Notes:
Estimated DIY installation time is 11 hours. A CV front driveline is required on 4WD models if operating in 4WD above 20 mph to prevent driveline vibration and component wear.
