  • i.b. Rigid Front Suspension – Deep Drop Rigid

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.
