Swivel Insert 32 Spline

The Winters Swivel Insert 32 Spline (part number 2976-32) is a precision driveline component engineered for high-performance automotive and racing applications where torque delivery and shaft alignment demand reliability. This swivel spline insert facilitates smooth power transmission by allowing controlled angular movement between drive shafts, making it essential in performance differentials, transfer cases, and custom drivetrain assemblies where misalignment or cyclic stress occurs.

Manufactured from steel with a polished finish, this component resists corrosion and oxidation while providing the hardness required for repeated torque cycles. The 32-spline configuration matches common OEM and aftermarket differential designs, ensuring compatibility with standard driveline architectures. Each insert includes a snap ring for secure retention, eliminating the need for secondary fasteners and simplifying installation. At 0.48 pounds with compact dimensions (2.5 × 1.4 × 3.55 inches), the Winters swivel insert integrates cleanly into tight packaging environments without compromising performance or longevity.

This component is designed for serious off-road enthusiasts, racing teams, and performance shops building custom drivelines for trucks, buggies, and competition vehicles. The polished steel construction and engineered spline geometry make it ideal for applications where articulation, torque multiplication, or shaft angularity challenges stock driveline geometry. Winters' reputation in the racing and 4x4 community reflects decades of validation in demanding conditions—from desert racing to rock crawling to oval-track competition.
