Understanding the issues associated with "big lift" (3-6 inches)

Larger lifts ranging from 3-6 inches may or may not be legal in your state.  Every state has its own lifted truck laws, and no two states are exactly alike. Please be sure to check your local laws.

With lifts this high, a number of components become affected which can cause possible driveline vibration and steering geometry issues. These lifts may require gearbox/driveline spacers, adjustable upper and lower control arms both front and rear, adjustable pan hard rods, caster correction kits and brake line extensions… the list goes on!

Larger lifts also have a greater effect on vehicle handling due to the increased center of gravity which needs to be addressed to avoid issues with cornering and braking.
