NAPA CV Joint (NCV1239) Fits: Mazda

This NAPA CV Joint (NCV1239) Fits: Mazda and is designed and manufactured to meet or exceed the quality of the original part, with each part rigorously tested to OE specifications.

A CV (constant-velocity) joint lets a driveshaft deliver smooth, constant torque while the shaft is steering and/or moving up and down with the suspension. Unlike a simple U-joint, a CV joint keeps the output speed equal to the input speed even at sharp angles, so you don’t get vibration or shudder.
