CNC machined from 6061 billet aluminum and anodized red, the iShock travel reducer's split core design is easily installed and removed by the rider allowing for travel changes to accommodate different tire sizes. A perfect example of this is the need to reduce the travel on the front of an ATV when equipped for small tires for motocross and then within seconds, remove the travel reducer when prepping for off-road and trail. Another perfect use is an UTV application; when running oversized tires in combination with aftermarket suspension, it is often necessary to reduce the travel to allow for adequate tire clearance. Available in 12, 14 and 16mm.
