Skyjacker C9661B 6-Inch Suspension Lift Kit Component Box - Rear/Secondary Kit

The Skyjacker C9661B is the secondary component box for Skyjacker's 6-inch suspension lift system designed for 1999–2002 Chevrolet K1500 and GMC Sierra 1500 4WD pickup trucks. This component box works in conjunction with the primary box (C9661A) to deliver the complete 6-inch lift when combined as the full C9661K lift system.

Skyjacker engineered this kit with a no-destruction philosophy — no cutting of the upper front differential housing mount is required, and no driveshaft replacement or modification is needed. This makes the system fully reversible and simpler to install compared to competing kits.

Key Features:

• 6-inch front and rear suspension lift height
• CNC machined steering knuckles for precise fitment and durability
• Integrated 2-piece, 4-point skid plate for undercarriage protection
• Drop bracketry for the front upper differential mounts
• Heavy-duty crossmembers that drop the lower control arms
• No cutting of the upper front differential housing mount required
• No driveshaft replacement or modification needed
• Components powder coated black to resist corrosion
• All necessary mounting hardware and detailed instructions included
• Estimated install time: 5–6 hours

When complete, the 6-inch lift system accommodates up to 35-inch tires mounted on wheels with a maximum backspace of 4.5 inches (stock wheels are not compatible). A steering stabilizer is strongly recommended but sold separately. Skyjacker suspension lift kits are backed by a limited lifetime warranty.

Note: This is a component box (Part 2 of 2). Shock absorbers and replacement rear leaf springs are available separately. Refer to the full C9661K kit listing for complete system contents.
