What happens to your turning diameter once Quigley install your Independent Front Suspension (IFS) 4x4 system? Nothing, your turning diameter remains the same as the 2-wheel drive OEM GM vans. The diagram below shows you how a turning diameter is calculated and corresponding table shows you the comparison between our 4x4 IFS system and GM’s OEM 2-wheel drive. The left turning diameter and the right turning diameter are not always the same; therefore you must calculate it as an average of the 2 turns.
