Our Recoil clutch weights are easily adjustable with simple magnets.  They have a custom AA profile, the BEST coating on the market (nitrocarburizing) which has increased wear resistance, improved fatigue strength, and added surface lubricity. These clutch weights also offer great performance, and the ability to tune for many different applications or modification in the future, without the need to buy extra parts.  The magnetic weights are the best option to properly place the mass where we need it on the weight for best performance for your application. Weights are sold in sets of 3 with enough magnets to fill the arm full No setup sheet is included as these are replacements for arms in our clutch kit, or those wanting to do their own clutch tuning
