  • Rigid Front Suspension– Deep Drop

Compromising the gap between engine sump and axle beam, and certain level of ground clearance; deep drop versions have been engineered to fit into the limited space, avoiding any collision at lowered engine position for flat floor passage in front.

Deep drop products are available for city-bus like applications, ready to fit to chassis.

  • Independent Front Suspension– Traditional

As known, IFS -the latest in axle technology for city buses and coaches offers improved roll stability, better comfort at ride & handling and wider aisle corridors compared to rigid suspensions.

BRIST independent front suspensions for “maintenance-free” concept based on patented T-joint design avoids the need of installing central lubrication system for greasing nipples. (Cost saving)
