It accepts a 3\/4\" spline on one end (36 splines) and a 3\/4\" double-D (DD) bore on the other, providing a simple mechanical connection for steering columns, rock crawlers, street rods, and small industrial drives. The piece is engineered to operate up to 4000 rpm and offers a working angle up to 35° for moderate misalignment while maintaining a small footprint for tight installations.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the exact dimensions and mechanical ratings of this coupling?\u003c\/h3\u003e\n\n\u003cp\u003eThe coupling measures 3-1\/4\" overall length with an outside diameter of approximately 1-5\/8\". One end accepts a 3\/4\" maximum spline diameter with 36 splines, the opposite end accepts a 3\/4\" maximum DD bore. Maximum recommended operating speed is 4000 rpm and the maximum working angle is 35°.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eOverall length: 3-1\/4\" (82.6 mm)\u003c\/li\u003e\n  \u003cli\u003eOutside diameter: 1-5\/8\" (approx.)\u003c\/li\u003e\n  \u003cli\u003eEnds: 3\/4\"–36 spline on one side, 3\/4\" DD on the other\u003c\/li\u003e\n  \u003cli\u003eMax operating speed: 4000 rpm; max working angle: 35°\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does this coupling install and what should I verify before fitting?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation is straightforward: slide the correct shaft into the matching bore (spline end or DD end) and secure per your vehicle or equipment's retaining method.
