Questions and Answers

On this lift kit, it says 4" backspace on wheel. What does that mean?
View Staff Answer 
Answer
Backspacing is the measurement from the hub mounting surface, to the back edge of the wheel typically in inches. This can be measured by putting the wheel face down, and measuring the length from the mounting surface to a straight edge laid across the back.
