Raises the front of the truck 3 inches so it sits level with the rear instead of nose-down. These trucks use torsion bars up front, so the kit works by cranking the torsion keys and correcting the geometry with new upper control arms and front shock spacers. Cognito rates it for a 33x12.50 tire on a 9-inch wheel with 5 inches of backspacing.

why this one — Choose this over a cheap crank-only leveling kit because the included upper control arms fix the ball joint angle that torsion cranking throws off, which is what kills ball joints and ride quality on cranked trucks. The trade-off is money and time: a bare torsion key kit costs a fraction of this and installs in an hour. This one is for owners who plan to keep the truck and drive it loaded.

why no number is shown

Suspension leveling kit, not a power-related part.
