Although Bell is phasing out the original style Kam-Lock (ratcheting) shields, owners of older helmets don't need to worry. This kit includes all of the hardware required to convert a Bell helmet with the older ratcheting Kam-Lock pivot to accept the newer SRV Friction-Lock Shields. The conversion is not permanent, so you don't have to replace all of your shields if you only need one new one. One kit converts one helmet. Black only.
