Simpson Hybrid D-Ring Helmet Anchor Fitting Kit

The Simpson Hybrid D-Ring helmet anchor fitting kit supplies D-Ring-style helmet attachment hardware for a compatible Simpson Hybrid tether arrangement. It is a helmet-side fitting kit, not a complete frontal head restraint (FHR) device, and is different from standard post anchors and M61 quick-release anchors.

Match the helmet, anchor and tether system

Start with the exact helmet model and its existing FHR anchor provision, then check the tether attachment on your Hybrid device. The anchor, mounting hardware and device-side connection must be matched as a system. A Snell rating or a similar-looking fitting alone does not establish compatibility.

This kit is listed for use with the Simpson Hybrid Sport SFI D-Ring restraint. Confirm the supplied device's attachment configuration before ordering. Do not assume D-Rings, standard HANS-style posts and M61 quick-release anchors use interchangeable tethers.

Before fitting

• Identify the helmet model and its manufacturer-provided anchor provision.
• Check the mounting hardware and installation instructions for that exact helmet.
• Check that the Hybrid tether connection is intended for D-Ring anchors.
• Follow the helmet and restraint manufacturers' installation and inspection instructions.

Do not drill or alter a helmet's protective structure, improvise a thread or substitute hardware based only on a product photograph. Ask us to help identify the correct kit if the existing mounting provision is unclear. Any nut or retaining-washer arrangement must follow the instructions for the supplied kit and helmet, rather than being treated as a universal extra-security option.

Compare the different Simpson fittings

If you need to compare a different mounting arrangement, see the Simpson Hybrid 6mm helmet fitting kit. Do not assume an unthreaded helmet can accept it without checking manufacturer-approved provisions.

For a matching quick-release system, compare the Simpson M61 quick-release helmet anchors. The Simpson Hybrid post-clips tether set is another attachment arrangement, not an implied D-Ring-compatible accessory.

NZ and Australian motorsport selection

For circuit racing, rally, off-road and other motorsport applications, check the physical labels on your exact helmet and restraint, their configuration and your category's current rules. Have the event organiser confirm acceptance where needed. Fitting an anchor kit does not give an older helmet a newer certification or guarantee NZ or Australian event eligibility.

Frequently asked questions

What is included in this listing?

This is the D-Ring helmet anchor fitting kit, not a helmet or complete FHR device. Confirm the exact supplied fasteners and package contents before ordering.

Does a Snell rating prove the kit will fit?

No. Check the exact helmet model, its anchor provision and manufacturer instructions, along with the Hybrid tether arrangement.

Is it the same as M61 or standard post anchors?

No. These are different attachment systems. Match the helmet anchors to the correct device-side tethers.

Can I fit it to a helmet without an existing thread?

Do not assume so or improvise a mounting point. Check the helmet manufacturer's approved provision and the fitting-kit instructions before selecting hardware.

Does fitting the kit make my helmet eligible for racing?

No. Eligibility depends on the physical labels, complete configuration and current category and event rules. An anchor kit does not upgrade helmet certification.

Can Harris Race Radios help identify the right kit?

Yes. Send your helmet model, photos of the anchor provision and Hybrid device details so we can help compare compatible arrangements.
