JLWF sponsor Icon Vehicle Dynamics offers a 2.5″ suspension system for all levels of use. They’re able to cover all bases because there are no less than 8 stages to their suspension system!
While that sounds like it could get confusing, the various stages are all explained in this suspension system stages diagram.
There’s also an accompanying video which not only provides an explanation but some cool looks at the Icon Vehicle Dynamics JLUR in action!
