ARK Racecar Chew Necklace - Sensory Chewelry for ADHD, Autism & Sensory Regulation

The ARK Racecar Chew Necklace is a wearable chew pendant made from medical-grade elastomer, designed for children, teenagers, and adults who benefit from safe, purposeful chewing as a tool for self-regulation. Manufactured by ARK Therapeutic in Columbia, South Carolina, USA, the Racecar is available in three colour-coded toughness levels to match individual chewing strength and need. It supports focus, calm, and sensory regulation for people with ADHD, Autism Spectrum Condition (ASC), and sensory processing differences.

A Safe Alternative to Destructive Chewing

Chewing on pencils, shirt collars, fingers, and nails is a common sensory-seeking behaviour across a wide range of neurodivergent profiles. The ARK Racecar Chew Necklace gives that oral input a safe, hygienic, and socially neutral outlet. The racecar shape features built-in aerodynamic textures that deliver additional proprioceptive feedback to the jaw and masseter muscles - the textures make chewing more satisfying and effective for sensory seekers. The cord threads ingeniously through the back wheels of the car, giving the pendant a natural hang point and making it easy to bring to the mouth.

The pendant measures approximately 6.4 cm tall, 3.0 cm wide (2.5 cm not including the wheels), and 1.5 cm thick at the centre. It comes on a 30-inch adjustable breakaway black cord with a safety clasp that releases under tension. It is suitable for front-teeth chewing and is a robust option for avid chewers.

Three Toughness Levels for Every Chewing Profile

Each Racecar pendant is available in one of three colour-coded toughness levels, making it straightforward for parents, SENCOs, occupational therapists, and workplace assessors to select the right resistance:

• Standard (softest) - Red, Dark Blue: recommended for mild chewers who do not chew through items.
• XT / Medium Firm - Lime Green, Bright Blue: the mid-range Xtra Tough level, firmer and longer-lasting, recommended for moderate chewers.
• XXT / Very Firm - Royal Blue, Forest Green, Orange: the Xtra Xtra Tough level, very firm and highly durable, recommended for avid or persistent chewers.

Who Benefits from the ARK Racecar Chew Necklace

• At home: gives children and teenagers a safe chewing outlet during homework, screen time, or periods of anxiety - reducing damage to clothing, stationery, and fingers.
• At school: discreet enough to wear throughout the school day; supports focus during lessons and reduces disruptive oral habits in the classroom. Compatible with sensory diets and EHCP provision. Suitable from EYFS through to sixth form and beyond.
• At work: a discreet and professional-looking tool for neurodivergent adults managing oral sensory needs at the desk, in meetings, or during periods of concentration.

Supporting ADHD, Autism, and Sensory Processing Differences

For people with ADHD, oral stimulation is a recognised self-regulation strategy. Chewing provides rhythmic proprioceptive input that can reduce restlessness, support sustained attention, and offer a healthy outlet for excess energy or anxiety. The ARK Racecar Chew Necklace is always to hand, requiring no set-up and no instruction - just wear it and use it when needed.

For autistic individuals, chewing is often part of a broader pattern of sensory-seeking or stimming behaviour that serves an important self-regulatory function. Providing a dedicated chew tool like the Racecar respects and supports that need, while keeping the behaviour safe. The familiar, predictable texture of the elastomer can also be soothing in itself.

For those with sensory processing differences who are oral sensory seekers, the Racecar's aerodynamic textures offer richer tactile feedback than a smooth chew - making it a particularly effective option for those who find smooth surfaces insufficient. The three toughness levels allow the resistance to be matched precisely to the individual's sensory threshold.

Medical-Grade Materials, Made in the USA

All ARK chew products are made from food-safe, medical-grade elastomer in ARK's own factory in Columbia, South Carolina - a manufacturing approach that ensures consistent quality and safety. The Racecar is latex-free and can be cleaned by handwashing or on the top rack of a dishwasher.

Whether you are a parent looking for a practical solution, a SENCO sourcing tools for a sensory diet, or an employer supporting a neurodivergent team member, the ARK Racecar Chew Necklace is a robust, evidence-informed, and easy-to-use option.

• Racecar-shaped chew pendant with aerodynamic textures: the built-in textures provide additional proprioceptive feedback to the jaw, making it more satisfying and effective for oral sensory seekers than a plain smooth surface.

• What is the ARK Racecar Chew Necklace and who is it for?
  The ARK Racecar Chew Necklace is a wearable sensory chew pendant made from medical-grade elastomer, designed for anyone who benefits from safe chewing as a self-regulation tool. It is suitable for children aged 3 and above, teenagers, and adults who have ADHD, Autism, sensory processing differences, or other conditions involving oral sensory seeking. It can be worn at home, at school, or at work.
• Does the ARK Racecar Chew Necklace help with ADHD?
  Yes - the Racecar Chew Necklace is widely used to support focus and self-regulation in people with ADHD. Chewing provides rhythmic proprioceptive input to the jaw, which can help reduce restlessness, channel excess energy, and support sustained attention during tasks. It is a discreet, always-available tool that requires no instruction and no set-up time.
• Is the ARK Racecar Chew Necklace suitable for autistic children and adults?
  Yes - the Racecar is suitable for autistic individuals of all ages who chew or stim as part of their sensory regulation. Providing a dedicated, safe chew tool respects this need while keeping the behaviour hygienic and socially acceptable. The consistent elastomer texture can also be reassuring in itself for autistic users who value predictability.
• Can this chew necklace help with sensory processing differences?
  Yes - the ARK Racecar is particularly well suited to oral sensory seekers who have sensory processing differences. The built-in aerodynamic textures provide richer tactile feedback than a smooth pendant, and the three toughness levels allow the resistance to be precisely matched to an individual's sensory threshold, from mild to avid chewing need.
• Which toughness level should I choose?
  ARK Therapeutic uses a colour-coded system across all its chewelry. Standard (Red, Dark Blue) is the softest and is recommended for mild chewers who do not chew through items. XT/Medium Firm (Lime Green, Bright Blue) suits moderate chewers. XXT/Very Firm (Royal Blue, Forest Green, Orange) is the most durable level and is recommended for avid or persistent chewers. If in doubt, start with the next level up from your estimate of the chewing strength.
• Can children use the ARK Racecar Chew Necklace at school?
  Yes - the Racecar is designed to be worn throughout the school day. It is discreet enough not to draw attention in a classroom setting and can be included in a child's sensory diet or EHCP provision. It is suitable from EYFS through to sixth form and is frequently recommended by occupational therapists and SENCOs as an oral motor regulation tool.
• Is the ARK Racecar Chew Necklace suitable for adults at work?
  Yes - the racecar pendant has a compact, purposeful appearance that is appropriate for workplace settings. Neurodivergent adults who benefit from oral stimulation to maintain focus during meetings, desk work, or training will find it a discreet and effective option. It may be considered a reasonable adjustment under the Equality Act 2010 and could be included in a workplace needs assessment or Access to Work recommendation.
• What age is the ARK Racecar Chew Necklace suitable for?
  The Racecar is recommended for ages 3 and above, with direct supervision required for younger users. It is equally suitable for older children, teenagers, and adults - ARK designs its chewelry for lifelong use, not just childhood.
• Is the ARK Racecar Chew Necklace safe to use?
  The Racecar is made from food-safe, medical-grade elastomer and manufactured in ARK's own factory in Columbia, South Carolina, USA. The 30-inch cord features a breakaway safety clasp that releases under tension, reducing the risk of injury. Users should regularly inspect the pendant for signs of wear and replace it at the first sign of damage. The cord and clasp are not intended for chewing.
• How do I clean the ARK Racecar Chew Necklace?
  The pendant can be cleaned by handwashing with soap and warm water, or by placing it on the top rack of a dishwasher. Regular cleaning is recommended, especially when used daily.
