Unique design means NO tools are required to make adjustments to the spring. It also has finer adjustments and all aluminum parts have been anodized so it looks better and performs better than alternatives.

A boost gauge is required with this product so you can set/monitor you boost levels. Order the boost bolt to pair perfectly with your spool stick!
