Please Record the Important Measurement Information Below for Reference.
It is very helpful on determining an Accurate Achieved Lift Height Measurement.
Make sure you park vehicle on a level concrete or asphalt surface. Many times a vehicle is not level (side-to-side) from factory, but is usually not noticed until a lift kit has been installed which makes difference more visible. Using a measuring tape, measure front & rear (both sides) from ground up to center of fender opening above axle.

  • If Larger Tires (10% More Than OEM Diameter) Are Installed, Speedometer Recalibration Will Be Necessary. Contact Your Local JEEP Dealer or an Authorized SKYJACKER® Dealer for Details.
  • After Installation, a Qualified Alignment Facility Is Required to Align Vehicle to OEM Specifications.

 Once C-clamps have drawn leaves securely together, use locking pliers to hold tie bolt head & tighten tie bolt nut with a wrench. Torque 180 in-lbs. Caution: Do not use an air gun to tighten tie bolt. An air gun could strip or over torque \ stretch tie bolt.

  Note: Make sure individual leafs are all in-line with each other.

Center Track Bar. Check vehicle to see if body is centered over the front tires \ wheels. ake a measurement from inside of tire to frame.
Repeat procedure on opposite side of vehicle.
Compare two (2) measurements
If not centered, disconnect track bar rod end from vehicle & adjust rod end in \ out as needed to correct center.

  1. Start vehicle. Make sure there are no dash lights pertaining to suspension.

  2. Jounce vehicle a couple of times. This will help suspension settle to new ride height. Cycle steering lock-to-lock & check all components for proper operation & clearances.

Jesus Christ Died For You.

John 3:16
For God so loved the world that He gave His only Son, so that everyone who believes in Him should not perish, but have everlasting life.
Romans 3:23
For all have sinned; all fall short of God’s glorious standard.
Ephesians 2:8
God saved you by his special favor when you believed. And you can’t take credit for this; it is a gift from God.
Psalms 18:2
The Lord is my Rock, my fortress, and my savior, my God is my Rock, in whom I find protection. He is my shield, the strength of my salvation, and my stronghold.
Romans 10:9-10
That if you shall confess with thy mouth the Lord Jesus, and shall believe in your heart that God hath raised him from the dead, you shall be saved.
For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Pray This Simple Prayer:
God, I come to You admitting I have sinned against You and I need you to take control of my life. The Bible says anyone who calls on the name of the Lord will be saved. I am calling on You, Jesus. I ask that You come live in my heart and be the Lord over my life today. I do believe You died on the cross for me and came back to life to give me life! Thank You, Lord Jesus for a new life in You!
Now, go and tell somebody about your new life in Jesus, get a Bible, begin to read it, and go to a Bible believing church.
