Fits late SA2005 Bell M2, M4, M4 Top Air, M4 Pro, BR-1, BR-1 Side Air, and Sport II Forced Air helmets with the SRV shield system. Bell reference number 280-SRV.
Bell introduced the SRV friction-lock system as a rolling change in 2005-06 on the SA2005 M4 and BR-1 helmets. Later SA05 versions of these models have the SRV system, but some of the early SA05 helmets have the original Bell Kam-Lok Shield detent system. The SRV shield has a smooth curved slot in front of the pivot. The Kam-Lok shield has a slot with three notches and takes a different shield.
Older M2, M2 Pro, M2 FA, M4, and M4 Pro helmets with the Kam-Lok detent can use this SRV shield with the addition of the Bell Kam-Lok to SRV Pivot Conversion Kit, Part No. 2239-010 (sold separately).
