Pro-werks 5/8-36 Spline X 3/4 Inch Bored Roller Bearing Steering U-Joint

5/8-36 Spline X 3/4 Inch Bored Roller Bearing Steering U-Joint, fits 6.4:1, 10:1, 12:1, 15:1 Stiletto Rack-n-Pinion The pressure angle of this spline is unique to Stiletto, this spline will not fit other 5/8-36 OEM type applications. 1/4-28 NF set screws on splined end   Precision in Motion These durable and smooth operating U-joints are engineered for high load applications. Precision machined alloy steel bodies are fitted with caged needle bearings and a slight pre-load to create a joint without backlash. This results in enhanced sensitivity at the steering wheel, making even the smallest amount of steering input more effective.  Designed for longevity without compromise, they are pre-greased and effectively sealed with hi temp O-rings to retain grease in severe conditions. Capable of a maximum of 32 degrees of operating angle, with a recommended angle not to exceed 20 degrees for the smoothest result. The splined ends of these U-joints are sized correctly; we have found that this is often not the case with competitive brands of U-joints, as they have designed their spline broaching tooling off of generations of parts in service and not to the original manufacturers specifications.
