Frequently Asked Questions

Get answers to the most common inquiries about our products and services.

What is the difference between a CV axle and a drive shaft?

A CV (constant velocity) axle is a type of drive shaft that uses CV joints to transmit power smoothly even when the suspension moves up and down. All CV axles are drive shafts, but not all drive shafts are CV axles.

Are your CV axles compatible with OEM specifications?

Yes, all AxleCV products are engineered to meet or exceed original equipment manufacturer (OEM) specifications in terms of dimensions, materials, and performance.

What does "EXTREME Weather Unit" mean?

Our EXTREME Weather Unit designation means the CV axle features TPEE boots and specially sealed joints that can withstand temperatures from -40°C to +150°C, making them ideal for harsh climates.

Do you offer custom OEM/ODM solutions?

Yes, we specialize in OEM and ODM manufacturing. Our R&D team in Los Angeles works closely with clients to develop customized CV axle solutions for specific vehicle models and market requirements.

What materials are used in your CV joints?

We use high-grade materials including 20CrMnTi steel for cages, CR steel for dampers, and 20Cr steel for tripods. All materials undergo proper heat treatment for maximum durability.
