Why are Portal-Tek Axles advantageous to a suspension lift?
. Suspension lifts increase the distance between the axle and the frame. This allows you to use larger tires, which in turn gives you some TRUE LIFT. EX: Lifting a truck 10″ will allow you to run a taller tire, but the TRUE LIFT is only equal to the radius or half of the height difference of your new tires verses your old tires. 36″ tires are 3″ taller than 33″ tires, but the radius of that is only 1.5″, thereby in order to gain 1.5″ of TRUE LIFT, you have to lift your vehicle tall enough to clear a larger diameter tire. The downside of this is by lifting your vehicle higher you sacrifice a low center of gravity and increase stress on suspension mounting points, drive shaft angles, and steering geometry. A Portal Axle running no suspension lift and a 33″ tire will give you 4.5″ of TRUE LIFT with no changes to suspension and/or steering geometry and minimal changes to center of gravity. 36″ tires will give you 6″ of TRUE LIFT with the same minimal negative effects.
