    Pre-Assembled Kit - fits lift type
    Spring Lift or Leveling Kit [1 to 3.5-inch lift]

    Spacer Lift, Leveling kit, and Spring lift kit

    These kits cause the upper arms to angle downward toward the ball joints. The Leveling kit or strut lift removes the factory rake angle by lifting the front level with the rear of the vehicle.

    Spring kits remove the factory rake angle and lift the rear of the vehicle about 1.5" - 2.5"

    These kits cause the upper arms to angle downward toward the ball joints. The cradle drop lift, cross-member drop, or drop bracket lift kit with spring kits.

    Example: 4" cradle drop lift with a 2" spring/coil over lift = 6" lift kit. 6" cradle drop lift with a 2" spring/coil over lift = 8" lift kit. When the mounting holes are offset by 4" and the kit is a 6" kit, the other 2 inches are made up from the strut lift or spring lift.
