The Straton Springer by Lowbrow Customs is inspired by Harley-Davidson springer front ends of the 1940s, but it’s been modernized where it matters. While it keeps the timeless antique styling, several improvements make installation cleaner, easier, and more builder-friendly.

LENGTHS

Straton Springers are based on a Standard length of 18″. This is measured from the underside of the lower tree (where the stem is welded) to the centerline of the axle. Any different in length is expressed in comparison to the standard length; for example, a 24″ long springer is considered +6″, as it is 6″ more than the standard 18″ length
