The jounce bumper is the upward movement or compression of suspension components and
is used to stiffen the suspension gradually as it approaches the end of the jounce
travel and prevent metal-to-metal contact that could lead to suspension damage or
failure. Also called as “bump stop”. The jounce bumper absorbs impact and dampens
noise, vibration and harshness during shock impacts caused by heavy loads, potholes
or objects in the road. There are four types of jounce bumpers supported in the
Truck Library.
- Front/rear external jounce bumpers
- Front/rear internal jounce bumpers
- External bumpstops-property file based
- Internal bumpstops-property file based
