Finished in corrosion-resistant chrome\/powder coating and crafted from steel, it provides a compact connection with a 3-1\/4\" overall length and a 1-5\/8\" outside diameter. The coupling works with two 3\/4\" DD shafts (no splines) and is rated for working angles up to 35° and operating speeds up to 4,000 rpm, making it suitable for a wide range of light-vehicle and custom steering applications.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this coupler fit into a steering column repair?\u003c\/h3\u003e\n\n\u003cp\u003eThe RABROPAR coupler mates directly to steering shafts with 3\/4\" DD ends, allowing a straightforward swap when an original U-joint is damaged.
