Built from premium polypropylene webbing with high-grade steel hardware, the 394004 provides a secure, adjustable fit for adult drivers and is a required piece of safety equipment in numerous professional and amateur sanctioned racing series.\u003c\/p\u003e\n\n\u003ch4\u003eSFI 3.3 Certification and Why Arm Restraints Are Required\u003c\/h4\u003e\n\n\u003cp\u003eArm restraints serve a specific and critical safety function: they prevent a driver's arms from exiting the cockpit in the event of a rollover or impact. In open wheel and open cockpit racing, an unrestrained arm that exits the vehicle during a crash can suffer catastrophic injuries. Sanctioning bodies including NHRA, NASCAR, and numerous regional and club-level open wheel and open cockpit series mandate arm restraints meeting SFI 3.3 specifications as a condition of competition.\u003c\/p\u003e\n\n\u003cp\u003eSFI 3.3 is the SFI Foundation's standard for arm restraints. A product carrying this certification has been tested to verify it meets SFI's requirements for construction strength and performance. The 394004 carries the SFI 3.3 rating, making it compliant with the rules of organizations that reference this standard. Drivers should always confirm that their specific sanctioning body accepts the 394004 and that the SFI tag on their unit is within the required date range, as SFI-rated equipment carries expiration guidelines.\u003c\/p\u003e\n\n\u003ch4\u003eAdult Sizing vs. Junior Sizing\u003c\/h4\u003e\n\n\u003cp\u003eThe 394004 is sized for adult drivers. The cuffs on this model adjust from 10 inches to 15 inches in circumference, and the tethers extend out to 20 inches, accommodating the proportions of most adult arms. This range covers a wide variety of adult builds from smaller-framed adults through larger-framed drivers.\u003c\/p\u003e\n\n\u003cp\u003eFor junior and youth drivers, RaceQuip offers part number \u003cstrong\u003e3930093\u003c\/strong\u003e, which is built to smaller proportions with cuff circumference ranging from 7 to 10 inches and tether lengths up to 19 inches. If you are fitting a younger or smaller driver, the 3930093 is the appropriate choice. Both models carry SFI 3.3 certification. Never use adult-sized arm restraints on a junior or youth driver; proper fit is essential for the restraints to function correctly in a crash event.\u003c\/p\u003e\n\n\u003ch4\u003eConstruction Detail\u003c\/h4\u003e\n\n\u003cp\u003eThe 394004 uses premium polypropylene webbing throughout, with 2-inch width webbing for the cuffs and 1-inch width webbing for the tethers. Polypropylene webbing delivers the combination of strength and flexibility needed for a functional arm restraint: firm enough to contain the arm effectively, and pliable enough to allow normal driving motion. The hook-and-loop cuff closure allows drivers to adjust the fit to their specific wrist and forearm circumference without tools, and to don and doff the restraints quickly.\u003c\/p\u003e\n\n\u003cp\u003eThe tethers terminate in a high-grade steel ring. This steel ring is designed to slide over the shoulder harness end link, which means the arm restraints release automatically when the driver releases the shoulder harness. This integration with the harness release system is a safety-critical design feature: in an emergency, the driver or an extractor should only need to work the harness buckle, and the arm restraints will come free at the same time.\u003c\/p\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 pair of SFI 3.3 arm restraints (2 individual straps, each with an adjustable cuff and tether): one for the left arm and one for the right arm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFull Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e394004\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e887753138354\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSFI Rating\u003c\/td\u003e\n\u003ctd\u003eSFI 3.3\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCuff Circumference\u003c\/td\u003e\n\u003ctd\u003e10 to 15 in.

NHRA mandates arm restraints for open wheel cars including Top Fuel dragsters and certain other classes. Many open wheel circle track series, sprint car organizations, and open cockpit sports car series also require them. The specific requirement depends on the car type and series rulebook. Always review the current rulebook for your sanctioning body and car class to confirm whether arm restraints are required and what SFI rating is accepted.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I know if the 394004 fits me, or if I need the junior version?\u003c\/strong\u003e\u003cbr\u003eThe 394004 is sized for adults, with cuffs adjustable from 10 to 15 inches in circumference and tethers up to 20 inches. If your forearm circumference falls within that 10 to 15 inch range, the adult model fits. For younger or smaller-framed drivers whose forearms measure 7 to 10 inches in circumference, the junior\/youth model 3930093 is the correct choice. Using the wrong size can compromise the function of the restraint in a crash, so correct sizing matters.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I install the 394004 in my car?\u003c\/strong\u003e\u003cbr\u003eThe tether at the end of each arm restraint uses a steel ring that slips over the shoulder harness end link, attaching the arm restraint to the harness release system. The cuff wraps around the driver's forearm and is secured with the hook-and-loop closure. The tether length should be adjusted so that the driver's arms are held within the cockpit in the normal driving position without restricting steering movement. Specific installation details, including tether routing and attachment points, may vary by car and roll cage configuration. Consult your sanctioning body's technical regulations and a qualified fabricator or technical inspector if you are unsure of the correct installation for your specific vehicle.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo SFI-rated arm restraints expire?\u003c\/strong\u003e\u003cbr\u003eYes. SFI-rated equipment carries a date code, and many sanctioning bodies specify a maximum age for certified equipment. The SFI 3.3 certification tag on the 394004 will display a manufacture or certification date. Check your series rulebook for the specific expiration window, as it varies by organization. Expired SFI tags are generally not accepted at tech inspection even if the physical equipment is still in good condition.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre the 394004 arm restraints compatible with a HANS device?\u003c\/strong\u003e\u003cbr\u003eYes. The 394004 is designed to work alongside a HANS (Head and Neck Support) device. The arm restraints attach to the shoulder harness end links and do not interfere with the HANS tether connections to the helmet, which attach at the helmet's HANS posts. Both systems operate independently and can be used together. In fact, many sanctioning bodies that require arm restraints also require HANS devices, so compatibility between the two is a standard design consideration for products like the 394004.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the package include one restraint or two?\u003c\/strong\u003e\u003cbr\u003eThe 394004 includes a full pair: one left-arm restraint and one right-arm restraint, sold together as a set. Each restraint consists of an adjustable cuff and a tether with a steel attachment ring.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre the left and right arm restraints different from each other?\u003c\/strong\u003e\u003cbr\u003eThe two restraints included in the 394004 package are typically identical in construction and are not specifically handed (dedicated left vs. right). Each is installed on the corresponding arm with the cuff facing the same direction. Confirm orientation during installation to ensure the tether routing matches your harness attachment points on each side.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat do NHRA rules say about arm restraints?\u003c\/strong\u003e\u003cbr\u003eNHRA rules require arm restraints in certain open wheel and dragster classes. The NHRA Rulebook specifies that arm restraints must meet SFI 3.3 specifications for the applicable car classes. Rule requirements are updated annually, and the specific classes mandated to use arm restraints can change from year to year. Drivers should always refer to the current NHRA Rulebook for their specific class and consult with NHRA technical officials if they have questions about compliance. The 394004 carries SFI 3.3 certification, which is the standard referenced in NHRA arm restraint requirements.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use the 394004 in a closed cockpit car?\u003c\/strong\u003e\u003cbr\u003eArm restraints are primarily required and used in open cockpit applications where the driver's arms would otherwise be exposed outside the vehicle in a crash. In a closed cockpit car with a full roll cage and window net, arm restraints are generally not required and are not commonly used, as the window net serves the arm containment function. However, some series and car classes may have specific requirements. Check your rulebook to confirm whether arm restraints are required, optional, or not applicable for your car configuration.\u003c\/p\u003e","brand":"Racequip","offers":[{"title":"Default Title","offer_id":45948272181327,"sku":"RQP394004","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/racequip-394004-sfi-3-3-adult-arm-restraints-black.jpg?v=1782237915","url":"https:\/\/www.blackopsautoworks.com\/products\/racequip-394004-sfi-3-3-adult-arm-restraints-black","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
