A Bellow Kit, also known as a Drive Shaft Boot Kit or CV Boot Kit, is designed to protect the constant velocity (CV) joint on the drive shaft. It covers the CV joint and keeps grease sealed inside while preventing dust, dirt, and water from entering. This ensures smooth rotation, proper lubrication, and extends the life of the CV joint.
A complete Bellow Kit usually includes:
Rubber or thermoplastic boot (bellow)
Grease packet (for lubrication of the CV joint)
Clamps or clips (for securing the boot ends)
Sometimes circlips or fasteners (depending on design)
All components are designed for OEM fitment and easy installation.
Replace the bellow kit if you notice:
Cracks, splits, or tears in the boot rubber
Grease leakage around the wheel hub or suspension
Clicking noise when turning (sign of CV joint contamination)
Early replacement of a damaged boot prevents costly CV joint failure and ensures drivetrain reliability.
Check your vehicle make, model, year, and engine type, and match it with the OEM part number or CV joint type (inner or outer). You should also verify:
Drive type: Front-wheel drive (FWD), Rear-wheel drive (RWD), or All-wheel drive (AWD)
Boot dimensions: Inner diameter, outer diameter, and length
Joint position: Inner or outer side of the drive shaft
If you’re unsure, contact us with your chassis/VIN number for fitment confirmation.
Yes. A torn or leaking boot allows dirt and moisture into the CV joint, causing grease contamination and metal wear. If left unrepaired, the joint can fail completely, leading to vibration, noise, and eventual loss of power transmission. Replacing the boot early is much more cost-effective than replacing the full CV joint or drive shaft.
Yes. Our Bellow Kits are manufactured to OEM specifications, ensuring perfect fit, flexibility, and temperature resistance. Each kit includes all necessary clamps and grease for quick installation. All products are tested for durability and sealing performance, and come with a warranty against manufacturing defects.
