Universal Joints
Neapco universal joints are available for most domestic and import light-duty vehicle applications in a variety of series, sizes, and configurations, including conversion U-joints. We also provide universal joints for medium and heavy-duty trucks, buses and RV vehicles, construction and off-highway, agricultural, small vehicle and industrial applications. Neapco U-joints are designed and engineered to be serviceable, fit the vehicle, and perform like original equipment. We understand the need for superior quality to ensure long life, reduce downtime and save maintenance costs.
Our product offering includes permanently lubricated and greaseable universal joints for 1000–1810 series (light to heavy-duty), 2C–15C (wing style), AAM 1355–1485 series (light to medium duty), 1200–2600 series (domestic agricultural applications) and series 1–10 (metric agricultural).
Neapco’s universal joints, sold through driveline specialists and warehouse distributors, are designed by Neapco in the U.S. and manufactured globally. All Neapco U-joints are designed and produced to Neapco’s tight tolerances. As a primary U-joint supplier, we control critical design specifications and processes that are critical to the fitment, strength, and life of a universal joint.
Neapco Performance Series
Neapco Performance Series Universal Joints are the next generation of u-joints and outperform the leading competitor’s joints in ultimate strength and fatigue tests. Neapco Performance Series U-joints achieve this exceptional performance by paying close attention to the details that make big differences.
Features and Benefits
Enhanced design thrust washer with a low-friction additive to the material decreases stick-slip and provides lower heat generation, friction, and wear due to new geometry.
Increased trunnion diameter for optimum strength – The addition of a needle bearing and a reduction in grease reservoir depth increases the overall strength and improves stress distribution along the trunnion.
A quad-lip seal prevents grease purging and outside contaminants from entering the u-joints.
The journal/spider body configuration is optimized to provide smoother transitions – ultimately decreasing stress risers throughout the u-joints.
Neapco Performance Series Ultra-Performance Universal Joint Grease provides superior durability, greater water resistance, and is stable across a wide range of temperatures.
