What happens to your turning diameter once Quigley installs your Independent Front Suspension (IFS) 4×4 system? You actually get a small improvement.
The diagram on this page illustrates how turning diameter is calculated, and the table shows that for a given wheelbase, the Quigley 4×4 conversion gains about 1.5 feet on average. The left-turning diameter and the right turning diameter are not always the same; therefore, you must calculate it as an average of the two turns.
