1 Answered question

What "driveline modifications" are required to run this kit?

Asked by snake from United States on

Snake, Driveline modifications are not technically required however we do highly recommend replacing the drive shafts with longer ones designed for the 4" and up kits. Due to the differences with driveshaft lengths between years and body styles you will need to contact our sales team at 1-800-333-5535 and they will be able to get you a price. Please let us know if you have any other questions. Thanks!
