The Detent to SRV Conversion Kit allows helmets originally made for Detent Shields to be converted to accept the new SRV Shields. In 2006, the majority of Bell Racing helmets were converted from a Detent Shield Mechanism to the SRV Shield Mechanism.
The Converstion kit is a washer that is applied directly to the helmet, under the shield. Once the washer is applied, the SRV shield and sliders can be used.
The kit includes the washer and detailed instructions.
