Head Replacement Foam Left Side

The Head Replacement Foam Left Side (model 89HLS) from KIRKEY is a replacement padding component designed for use in racing seats. This foam is ideal for those who have upgraded their vehicle's seating to accommodate a racing harness or competition-grade bucket seat. As factory padding wears out under the demands of racing or spirited driving, this replacement foam provides a practical solution.

Constructed from high-density closed-cell foam, the 89HLS is engineered to maintain its shape and provide support during aggressive cornering. Its lightweight design, verified at 0.42 lbs, ensures minimal added mass while offering effective impact absorption to protect the cervical spine. The closed-cell structure also resists moisture and sweat, which helps prevent deterioration over time.

This left-side foam replacement is compatible with KIRKEY's modular seat architecture, allowing for incremental replacement of worn padding rather than a complete seat replacement. Mechanics and automotive enthusiasts often choose this foam to refresh their KIRKEY racing seats, making it suitable for various applications, from weekend track days to competitive racing.
