Now before anyone gets hurt feelings, I'll explain why. Let's start with the front suspension.

When you add taller coils or lift spacers, you change the geometry of the front control arms and track bar. A rule of thumb is for every 2 inches you move the front diff back about 3/4 inch and uncenter it under the frame about the same amount. So a 3 inch spacer will move the differential off center about an inch.

This results in A. Caster issues (high speed handling), B. Off tracking or "doglegging" of the vehicle, C. Changes the sway bar link angle causing deflection and loss of handling, and D. Accelerates wear on the track bar and ball joints.

Lastly, having the axle off center in the wheel wells can cause tire rub, defeating the entire purpose of the lift! BTW the off center can be noticable when the vehicle is viewed from the front.

A proper front suspension lift includes longer control arms, track bar bracketry or a better bar, and longer sway bar links or drop brackets for the bar. That way your components function and can be adjusted to factory settings.

For the rear, stacking blocks is a no no for a proper suspension. In addition to the danger of them popping out, they cause spring wrap which over time damages and de arches the springs causing them lose lift.
