The Zamp Z-Tech Series 6A is an adjustable SFI 38.1 head and neck restraint with a high back built for taller drivers. In our video with Zamp Racing, Zamp explains that the 6A's higher back and V-shaped tether webbing give it more left-to-right range of motion than the Z-Tech 2A, while keeping the same wide adjustment. This review covers who the Z-Tech 6A fits, how its back and tether work, how to set it up and what comes in the box. To compare every brand we carry, see our HANS devices and head and neck restraints.
The Zamp Z-Tech 6A is built for taller drivers with longer necks who sit in a more upright seat and want more side-to-side head movement than the Z-Tech 2A allows. Zamp Racing says the 6A is oriented toward taller, longer drivers, and it does not recommend the 6A for younger or smaller drivers.
That advice can look odd next to the 6A's one-size frame, which adjusts wide enough for a teenager or a large adult. The frame width is not what drives the advice. Zamp ties it to the higher back, which it says is what makes the 6A different from its other devices and why it is oriented toward drivers with a longer neck and taller build. Smaller and younger drivers are better matched to the Z-Tech 2A or the sized Z-Tech 8A. New to frontal head restraints? Read what a HANS device is and how it works first.
The Zamp Z-Tech 6A improves range of motion in two ways. Its patent-pending high back gives a more natural pull angle on the helmet. Its tether webbing is laced in a V-shape, so the clip can slide. Together they give the 6A more left-to-right movement than the Z-Tech 2A, whose tethers run in line.
In practice, that means you can check a mirror, look into a corner or watch the car beside you with less resistance from the tether. Drivers who spend the whole race looking forward may never notice the difference. Drivers who turn their heads constantly, in traffic or off-road, are the ones most likely to notice the 6A's extra movement.
You adjust the Zamp Z-Tech 6A with Zamp's Advanced Axis Adjustment system, which sets shoulder width, arm angle and arm width. The frame widens or narrows between 12.75 and 15.25 inches. The gray arms move up or down to become more cup-shaped or flatter, so they follow your shoulders under the belts.
Zamp's Z-Tech owner's manual gives the starting points: set the shoulder adjustment 1 inch wider than your neck width, then set the arm angle in your race seat so both arms sit snug against your body at the same angle without pressing in. Adjust the tethers so the clips engage the straps 1.75 to 2 inches from your natural driving position. The 6A is designed to work across different race seat configurations, so do the final check sitting in your own seat with your 2-inch or 3-inch belts tightened. Replaceable padding lets you refresh comfort later without replacing the device.
The Zamp Z-Tech 6A comes with everything needed to connect it to one helmet with pre-installed M6 inserts. The box includes the device, the helmet hardware, the clips and a small bag of Loctite to lock the anchors into the M6 terminals. Each 6A also ships with a new, dated SFI 38.1 tag.
If you switch between two helmets, add the Zamp Z-Tech Series 2A/3A/6A Helmet Anchors Kit for the second one.

The most common concerns about the Zamp Z-Tech 6A are whether it suits drivers who are not tall, whether it is worth paying more than the Z-Tech 2A, and whether it fits a given seat and belt setup. Each concern has a direct answer below.
It may be. Zamp Racing recommends the 6A for taller drivers with longer necks and does not recommend it for younger or smaller drivers, and ties that advice to the 6A's higher back. The frame width still adjusts, so average-height adults are not ruled out. If you are on the shorter side, compare the 2A and the sized 8A in our Z-Tech 2A vs 6A vs 8A comparison.
Only if you need the extra head movement or the taller back. The 6A costs more than the 2A, and both carry the same SFI 38.1 certification, so the extra money does not buy a higher safety rating. It buys the high back and the sliding V-shaped tether. Tall drivers who turn their heads often get real value from both.
The Zamp Z-Tech 6A fits most upright-seat setups, the application it is designed for. Its belt channel accepts 2-inch or 3-inch shoulder belts, which go over the shoulders. The SFI Foundation's seatbelt guide for upright seats, up to 25 degrees of recline, sets shoulder belts at 0 to -20 degrees from horizontal (-10 optimum), with a clear path from the top of the restraint to the harness bar. See how to install a racing harness.
The Zamp Z-Tech 6A is worth it for taller, upright-seat drivers who want more side-to-side movement than the 2A gives, without moving to the sized 8A. You get the device, helmet hardware for one M6 helmet, quick-connect clips, Loctite and a new five-year SFI 38.1 tag, ready to fit from the box.
Orders over $50 ship free to the 48 contiguous US states and Washington, D.C. See our shipping policy for details. FAST RACER accepts returns and exchanges within 30 days of receiving your order for eligible items that are unused and in as-new condition, in the original packaging with all labels, tags and literature. Check the fit before you install anchors in a helmet, because modified items cannot be returned. See our warranty page for how claims work. FAST RACER can act on your behalf with Zamp on a claim. Zamp's Z-Tech owner's manual covers defects in materials and workmanship for one year from purchase, and Z-Tech also runs an accident replacement program for a device damaged within two years of purchase. After a significant accident, the manual says to return the restraint to the manufacturer for inspection or replace it.
Yes. The Zamp Z-Tech 6A is sold in one size that adjusts in width from 12.75 inches at its narrowest to 15.25 inches at its widest. The arms also adjust in angle and width. Zamp Racing still recommends the 6A mainly for taller drivers with longer necks, because of its higher back.
Yes. The Zamp Z-Tech 6A uses the same helmet anchor kit as the Z-Tech 2A and 3A, part number NZHC001A. One set of anchors comes in the box for one helmet with M6 inserts. For a second helmet, add the Zamp Z-Tech Series 2A/3A/6A Helmet Anchors Kit. That kit does not fit the Z-Tech 8A.
The Zamp Z-Tech 6A weighs approximately 900 grams, or about 2 pounds. That is the same listed weight as the Z-Tech 2A, even with the 6A's higher back. The 6A uses the same dual compound frame, with a fiberglass reinforced nylon shoulder frame and modified alloy arms that add a dampening characteristic in a crash.
The SFI 38.1 tag on a Zamp Z-Tech 6A is good for five years from the month and year printed on it. Zamp Racing explains in our video that each 6A ships with the most up-to-date tag. Note that date when your device arrives, and confirm your series rulebook's expiry rule before tech inspection.
The patent-pending high back on the Zamp Z-Tech 6A provides a more natural pull angle and easier side-to-side movement. It is the feature that separates the 6A from the Z-Tech 2A, which shares the same frame, width range and weight. The higher back is also why Zamp Racing positions the 6A for taller drivers with longer necks.
The Zamp Z-Tech 6A is the right head and neck restraint for taller drivers with longer necks who sit upright and want more side-to-side movement than the Z-Tech 2A allows. Its patent-pending high back and sliding V-shaped tether are the reasons to choose it, and it adjusts from 12.75 to 15.25 inches wide with SFI 38.1 certification. The Z-Tech 6A is not the best choice for younger or smaller drivers, who Zamp Racing steers away from it. Check the 6A's current price and availability below.
