Jounce Bumpers: Everything You Need to Know
1/14/2014
Your tuck’s got ’em. Our air springs have ’em. They’re important in protecting your truck.
The jounce bumper.
Commonly known as a “bump stop,” the jounce bumper was initially used to prevent the abrupt and harsh bottoming-out of the suspension when under full compression.
Over the years this original design has changed and the jounce bumper has been integrated into the vehicle’s suspension design.
Commonly manufactured from closed-cell foam, the jounce bumper absorbs impact and dampens noise, vibration, and harshness by preventing the suspension components from fully compacting during shock impacts caused by heavy loads, potholes, curbs, or objects in the road.
The modern jounce bumper also acts as a progressive compression spring under loads that are approaching full compression, offering a smoother ride and improved handling over a wide range of driving and load conditions.
