Ironhead Sportster Narrow Glide to Wide Glide Neck Cup Conversion Set
This kit is designed and CNC machined from cold-rolled 1018 raw steel to convert 1952-1981 Harley Davidson Sportsters to accept wide glide front ends. This is the correct way to convert your Ironhead to run your favorite wide glide front end, aftermarket front end, or aftermarket springer front end. These neck cups are machined to press into your stock Ironhead frame, but to use Harley big twin style 1" ID tapered bearings. The cup height is designed to equal that of a big twin once properly installed. The contour of the neck cups provide excellent fit and finish while maintaining ideal structural integrity.
CNC machined for exact tolerances
Includes tapered bearings and races (races already installed)
Raw steel machine finish
Knurled at internal sleeve area to inhibit unwanted cup rotation
Made in the USA
