Neapco's distinguished history begins soon after the invention of the automobile. Originally the New England Auto Products Corporation of Hartford, Connecticut, the trademark of Neapco was adopted in 1921 and the company moved its universal joint manufacturing to Pottstown, Pennsylvania, a few years later.


In the 1930s, the company became a key supplier of universal joints and shafts to the farm implement market. During World War II Neapco redirected its resources to supply the U.S. Navy with projectiles and pin & block universal joints — becoming one of the first companies to receive the Navy “E” award for excellence. Over the next two decades industrial joints and shafts and heavy-duty driveline components for over-the-highway trucks were added to the product line.

Opened in 1981, Neapco's Beatrice, Nebraska, facility has undergone four major expansions to accommodate manufacturing for CV joints and drivelines, universal joints and a complete line of driveline components.


Our driveline component designs are tested and validated as part of our commitment to providing aftermarket parts that meet or exceed OE quality and performance standards. Our driveline components are produced using state-of-the art technology and manufacturing processes that allow for precision machining and control of tight tolerances.

Our light-heavy duty driveline component offering includes a full complement of part types, including but not limited to weld yokes, slip yokes, stub shafts, flange yokes and flange socket yokes, end yokes, centering and H yokes, CV head assemblies, companion flanges and driveline tubing.

Neapco offers a broad array of aftermarket double-Cardan CV head assemblies, including many with our proprietary lubrication system in the critical centering mechanism. This design improves grease flow to the important linkage between the CV yokes. The universal joint lock-up relationship to the pilot diameter and ball stud tube diameter reduces driveshaft run-out, which eliminates vibrations that can contribute to NVH.


Slip yokes and stub shafts machined to tight tolerances — Minimizes axial movement and/or hinging. We are considered the industry leader in providing heavy duty slip yokes and stub shafts with superior fits.

Dynamically balanced heavy duty slip yokes — Reduces or eliminates imbalance issues when assembling or repairing a driveshaft.

Nylon coated stub shafts — Prevents premature wear and axial movement.

Ductile iron or forged steel components — High strength design reduces ear-and-plug deflection for reduced warranty and risk of leaks under load.

Broad array of aftermarket double-Cardan CV head assemblies — Many with Neapco's proprietary lubrication system for the linkage between the CV yokes.
