The series 4-A is the replacement for the older 1-A using the lighter materials and updated design.
With multi-axis adjustments this advanced design head restraint system allows adjustment to shoulder width, arm angle and arm width.
Incorporating all of these adjustments gives it the ability to fit different body shapes and many different style race seats.
The dual compound frame is 25% lighter than previous models, featuring a fiberglass reinforced shoulder frame and arms manufactured with a modified alloy resulting in additional dampening in the event of a crash.
Kevlar tethers and stainless steel spring clip quick connectors are used for easy attachment/detachment from the helmet. Includes all hardware needed for attachment to helmet.
Meets SFI 38.1 specifications.
