Transmission

We Know Quality

The NAPA Transmission range covers a wide selection of OE-matching parts and accessories designed to maintain the performance of a vehicle’s engine and handling. Every driveshaft and CV joint in the NAPA catalogue has been subjected to manufacturing-level tests to ensure product reliability that carries through from the factory to installation. We produce the entirety of our transmission range in a fully certified facility that meets ISO9001, IATF16949 and ISO14001 quality and manufacturing standards.

We Know Our Products

NAPA Transmission products are equipped to help every fitment find its mark.

High-Quality Materials

NAPA Driveshafts and CV Joints are all made out of CF53 grade carbon steel for improved durability against the elements. Our driveshafts are supplemented with a corrosion-resistant phosphate coating to ensure better performance under extreme conditions for longer.

Surcharge-Free

Each part in our transmission range is 100% surcharge-free, meaning that they are made entirely of new parts and not remanufactured units. This eliminates the need for core returns to ensure you have the most seamless purchasing and installation process possible.

Production Tested

The driveshafts and CV joints in our range undergo a thorough breadth of testing procedures to guarantee that only products of the highest quality leave the factory. These tests include:

• Appearance Inspection
• Allowable Slippage
• Strength Testing
• Salt Spray Testing
• Durability Testing
• Heat & Cold Resistance Testing

That is why our driveshafts and CV joints are sold with a 3 year/36,000-mile no quibble warranty guarantee to protect our buyers against the unexpected.

Our team of technical experts are on hand to provide support and guidance on our range of transmission products.
