Head Replacement Foam Right Side

The Kirkey Head Replacement Foam Right Side (Part No. 89HRS) is a direct-fit replacement head support pad engineered for Kirkey 78, 88, and 89 series racing and performance seats. This right-side foam insert restores comfort and lateral support where factory foam degrades from extended use, heat cycling, and moisture exposure typical in high-performance driving environments. Available as an individual replacement unit, this foam addresses the specific wear pattern that develops on the driver's side headrest in vehicles subjected to repeated g-loading and continuous seat time.

Designed as a bolt-on replacement component, this head pad maintains compatibility with the existing Kirkey seat structure without requiring seat removal or frame modification. The foam density and profile are matched to OEM specifications for the 89 series platform, ensuring proper neck and cervical spine support during lateral acceleration events. At 0.84 lbs and measuring 7 x 3.55 x 17.9 inches, the right-side unit fits precisely within the seat's contoured cavity. The black finish integrates seamlessly with standard Kirkey seat upholstery and resists fading from UV exposure and interior heat.

This replacement is essential for drivers operating road-race, autocross, and performance vehicles where factory seat comfort has deteriorated. Track-day competitors and professional drivers recognize deteriorating headrest foam as a symptom requiring immediate attention—compressed or disintegrating foam fails to stabilize the head during cornering, reducing control precision and increasing driver fatigue over long sessions. Kirkey's modular replacement approach eliminates the cost and downtime of full seat replacement while maintaining the engineering integrity of the original design. The 89 series is favored in club-level racing, vintage performance restoration, and serious track enthusiast builds where reliability and comfort are non-negotiable.
