  • As known, independent front suspension technology is the latest axle technology. It has been widely preffered by buses and now increasingly demanded by electric trucks. Compared to a rigid front suspension, an independent front suspension offers improved roll stability, better comfort at ride & handling; , lower weight and wider aisle corridor.
  • Various types of BRIST IFS has proven its performance through the vehicles of its well-known customers across the globe. (e.g. BYD, Arrival, Isuzu, Otokar, and many more)
  • BRIST categorises its IFS products under 2 main sub-categories as “Generation#1” and “Generation#2” types
  • The main difference between these 2 sub-categories is that they have different kinematics with their own advantages
