Cognito Motorsports 210-91023 CV Front Driveline Kit for 4-6 Inch Lift Silverado Sierra 2500 3500

The Cognito Motorsports CV Front Driveline Kit is engineered to restore proper driveline angles on lifted GM trucks, eliminating vibration and increasing suspension travel. This direct bolt-in kit is designed for 2001-2016 Silverado/Sierra 2500/3500 trucks with 4-6 inch lifts on Duramax engines or 4-12 inch lifts on gas engines, and 1999-2006 Silverado/Sierra 1500 trucks with 7-12 inch lifts.

Key Features:

• Complete direct bolt-in CV driveline system—no modifications required
• 1310 series double cardan constant velocity joint for smooth power transfer
• 1330 to 3R combo u-joint at differential end
• Includes Cognito Allison Transmission Bracket for proper fitment
• Maximizes suspension travel and eliminates driveline vibration
• Made in the USA with high-quality materials

This kit is specifically designed to handle the increased driveline angles that occur when lifting heavy-duty GM trucks. The double cardan CV joint maintains consistent rotational velocity throughout the driveline's range of motion, preventing the characteristic vibration that occurs with standard u-joint configurations on lifted applications.

Important Note: Trucks equipped with the six-speed Allison transmission require Cognito part number 110-90278 shift linkage relocation bracket (sold separately) for proper installation.
