EVS R4 Adult Race Neck Protector

Weighing just 635 grams, the EVS R4 Race Collar is a lightweight, low-profile safety restraint designed to protect drivers from severe neck and collarbone injuries. This form-fitting protection system sits comfortably between the helmet and shoulders, working to disperse high-energy impact forces away from the cervical spine during a heavy landing, roll, or collision.

Engineered with a multi-layered defensive shell, the R4 features a high-impact polymer outer shield that deflects flying debris and roost. Beneath this sits a hard-moulded upper surface that channels impact forces into a high-tensile, closed-cell Polyurethane (PU) core and an energy-absorbing bio-foam liner. Equipped with an adjustable rear strut for a tailored fit, a front-entry Rapid Lock closure system, and an elastic cross-body strapping network, the R4 delivers reliable, non-restrictive safety for intensive short-circuit racing.

Key Technical Features:

• Multi-Stage Impact Core: Combines a high-impact tested polymer exterior, a closed-cell PU core, and a plush bio-foam underlay to absorb and redistribute impact energy.
• Cross-Body Elastic Strapping: Outfitted with EVS’s specialized elastic Cross Strap system to lock the collar securely against the torso, preventing shifting or riding up during high-speed heats.
• Rapid Lock System: Features a heavy-duty, fast-acting front push-button lock mechanism that enables quick, hassle-free entry and exit in the paddock.
• Adjustable Rear Strut: The rear support fin can be fully adjusted to customize the angle and seating depth against your back protector and racing harness profile.

Frequently Asked Questions (FAQs)

Q: Can this collar be worn comfortably with an Autograss high-back race seat?

A: Yes. The R4 features a highly compact, low-profile rear design and an adjustable rear strut, allowing it to sit cleanly against your back and neck without pushing your helmet awkwardly forward against a high-back competition seat.

Q: How do the cross straps connect to secure the unit?

A: The included elastic cross straps loop over the sides of the collar and cross under your arms, anchoring the frame flat onto your shoulders to keep it stabilized through rough ruts and vibrations.
