By HANS
Size

The industry's most trusted safety device just took a massive leap forward. The HANS IV is a complete redesign of the iconic Frontal Head Restraint (FHR), now 10% lighter than the outgoing HANS III, to significantly reduce neck fatigue. Beyond weight, comfort has been re-engineered from the ground up: new, custom-molded foam pads "nest" directly into the device to eliminate slippage and provide superior shoulder support. Now available in three precise sizes and a versatile 20-degree angle, the HANS IV offers professional-grade protection at a price point that makes elite safety accessible to every driver on the grid.

HANS Installation Instructions

Most modern Snell SA2015 and later and/or FIA8858/FIA8860/FIA8859 helmets have threaded mounting posts bonded into the helmet shell. This allows for very quick and easy installation without the need for specialty tools or helmet modification. If your helmet does not have these threaded mounting points, please get in touch with us for assistance.

Tools needed for installation:

  • 5/32 or 4mm Allen Key (put down your impact gun - either size will fit)
  • Hans Anchor Key/Wrench (not included) OR Hans Tether attached to your device

Instructions:

  1. Using the entire anchor, thread it onto the terminal on the helmet. Note that threadlocker has been pre-applied to the anchor's thread. If transferring the anchor to a new helmet, fresh threadlocker is recommended.
  2. Hand-tighten the screw until snug, making sure the point on the anchor faces rearward. When installing Quick-Click-style anchors, the opening hasp should point rearward. (Click here for sample image)
  3. Tighten the screw a ¼ turn past snug. You may need to hold the anchor still while tightening to ensure the point on the anchor remains facing rearward. This can be accomplished with the flat edge of a connected tether or using the specialty Hans Anchor Key (or similar flat spanner wrench). Note: Not a lot of force is needed to tighten this screw - if you are having problems keeping the point on the anchor in place, you're probably over-tightening! Overtightening can easily break the bonded anchor terminal and/or otherwise damage your helmet!
  4. Test your installation by connecting the Hans tether to the anchor and makeing sure it slides on/off with little resistance. If the anchor is installed too tightly, it will feel tight.
  5. That's it!
