Swivel Spline Coupler

The Winters Swivel Spline Coupler (Part Number 2975) is a precision coupling component designed for use in driveshaft assemblies. It is particularly useful in applications where shaft alignment and rotational flexibility are important. This coupler is ideal for custom builds, including drag racing and modified vehicles, where standard couplings may cause binding or vibration issues.

Constructed from hardened steel, the Winters Swivel Spline Coupler features internal spline geometry that allows for minor angular misalignment while maintaining reliable power transfer. The swivel action helps to distribute stress evenly across engagement surfaces, reducing wear and preventing the harsh clunk associated with solid couplers. This design is particularly beneficial in high-torque applications.

Mechanics and fabricators will appreciate the compact size of this coupler, which measures 4.55 x 3.6 x 6.5 inches and weighs 1.71 lbs, making it suitable for tight engine bays and custom configurations. The spline-lock design ensures positive engagement during acceleration and braking, enhancing performance and reliability in demanding conditions.
