Simpson Quick Release Sliding Tether Kit for HANS Devices

The Simpson Quick Release Sliding Tether Kit is an FIA-approved safety upgrade engineered to convert standard HANS devices into an instant-release system. If you are tired of wrestling with traditional slide-slot metal brackets inside a cramped cockpit, this kit offers a seamless path to effortless detachment. When combined with mandatory Simpson Quick Release helmet posts, this system allows you to completely sever the connection between your helmet and your HANS yoke with a simple, deliberate pull of an integrated release cord.

Unlike brand-exclusive upgrades, this universal kit is fully approved for installation on HANS devices from any manufacturer, making it a highly versatile modification for circuit racers, rally crews, and track day enthusiasts. The fluid sliding geometry allows the high-strength synthetic strap to glide smoothly through the rear channels of your HANS yoke, providing uncompromised lateral head rotation and wide peripheral vision when tracking apexes. Because maintaining correct tether slack is critical to your safety, this kit is available in three distinct, pre-measured lengths—allowing you to replace your current stock tethers like-for-like without altering your device's original safety parameters.

Key Features:

• Universal HANS Compatibility: Fully FIA approved to retro-fit onto any manufacturer's standard HANS device, instantly updating it to a modern quick-release configuration.
• Instant Tether Disconnection: Eliminates the classic hassle of twisting and angling rigid metal brackets to clear your helmet posts under tight time pressure.
• Three Fixed-Length Options: Available in 17-inch, 18-inch, and 19-inch variations to ensure you can replace your existing stock straps like-for-like, preserving engineered safety limits.
• Fluid Sliding Geometry: Keeps head movement free and natural, allowing smooth side-to-side head rotation without any binding or resistance through the yoke channels.
• Complete Installation Package: Supplied ready to fit with distinctive orange alignment clamps and high-tensile locking screws for a clean, secure hardware connection.

Frequently Asked Questions (FAQs):

How do I choose the correct tether length for my specific HANS device? It is vital for your safety that you match the length of your new quick-release straps exactly to the tethers currently fitted to your device. Lay your existing stock tether flat, measure its total operational length, and select the corresponding 17, 18, or 19-inch option from our sizing menu to ensure your head containment limits remain completely uncompromised.

• Can I use these tethers with the standard HANS posts that came on my helmet No. These specialized quick-release tethers feature a distinct mechanical locking profile and must be paired with Simpson Quick Release Helmet Posts (such as the M61 series). They will not lock onto or engage with standard, fixed-metal slide-slot HANS posts.
• When should I proactively replace my HANS tethers? Motorsport manufacturers strictly recommend that all safety tethers must be replaced immediately following any major crash or in-car fire event, even if no visible tearing is present. Over time, UV exposure and cockpit grit can also degrade the synthetic fibers; checking and replacing them every few seasons is best practice to guarantee complete structural integrity.
