CV Boots for OE & Aftermarket Manufacturers

KOK manufactures CV boots designed to protect driveline and transmission assemblies from contamination, supporting reliable joint operation and long service life.

We supply CV boots for passenger cars, motorcycles, ATVs, and industrial and agricultural equipment, with coverage across Japanese, European, and US vehicle platforms. Our products are developed for OE supply and aftermarket manufacturing, with a focus on consistent quality, fit, and material performance.

Engineered for Quality and Consistency

Our CV boots are manufactured using validated materials and controlled processes to meet the quality and consistency requirements of OE and aftermarket manufacturers. All materials and finished products are produced under strict quality controls and aligned with OE-level performance expectations.

In-house Design, Materials, and Testing

KOK provides in-house CV boot design, material selection, and validation support. We work with customer teams to develop new designs or optimise existing ones based on application requirements.

Available materials include neoprene, EPDM, TPE, and TPV, selected to balance flexibility, chemical resistance, durability, and temperature performance.

Finished designs are validated through in-house testing to confirm performance under representative operating conditions and to ensure compliance with customer and OE requirements.

Our vertically integrated design and testing capabilities enable efficient development, validation, and supply of CV boots for demanding driveline applications.
