We used a 22-degree ramp-travel-index (RTI) ramp provided by Mike Duncan of Four X Doctor to test the travel of the suspension before and after the 6-inch kit was installed. A ramp is a great measuring device for axle articulation and can help you determine what is limiting travel. Notice that we retained the 33x12.50-15 tires: This keeps the tires from hitting the fenders with the 6-inch lift, although it doesn’t increase the clearance under the axles.
