Complete and accurate reproduction of the classic H-D Springer fork as used by the factory on Big Twins 1936-49 and on 45” models from 1941–57. Manufactured just like back in the good old times, i.e. with forged legs and connecting components, which makes them equal to the original counterpart concerning stability and service life.
Use these top-quality forks as stock replacement for your restauration or as a part of your chopper or bobber project-bike.
Length is measured from axle center line to seat of lower steering head bearing.
1.) The pivot point of the brake shackle on the backing plate or caliper bracket must not be positioned vertically above or in front of the wheel axle (driving direction). In this case the moving forces in your fork parallelogram will be reversed and the fork will rebound instead of being compressed when you apply the brake. This will generate very high forces to impact on your rigid fork leg with possible damage.2.) Caliper bracket or drum brake backing plate must float on the wheel axle. If not, the fork will rebound as well when applying the brake. Result: see above.

Inline vs. Offset
Classic Springer Forks are produced for different frame rakes.
- In the beginning, both the main tubes and the steering stem were in the same plane. This is called "inline". The rake is 0°. Of this type were all 45” Springer forks 1936-1957 and all Big Twin forks 1936-1945.
- From 1946 onwards the Big Twins had the neck angle increased to 30°. To maintain fork inclination and ground clearance, the steering stem was tilted to the rear by 3°. We call these forks Offset -3°, they were stock on 1946-1948 Big Twins.
- When building a bike with ≥+8” extra long forks you don’t want the steering neck so high and inclined that the bike is difficult to steer. Therefore such forks are manufactured with a positive rake, i.e. the steering stem is inclined to the front by 3°. We call these forks Offset +3°.
Chromed Springer Forks
Springer forks are pretty complex products which are still manufactured on old style machinery to period specs. They feature lots of tight bends, numerous connections and many hard-to-reach spots which simply cannot be polished to a mirror-like finish with resulting imperfect chrome surface.
Moreover, the applied welding and soldering techniques make the forks prone to oxidation in the aforementioned spots, if not attended regularly. Sometimes even new forks can already show light oxidation here.To make a long story short: it´s a good idea to frequently apply a little WD40 into the dark corners of your fork, especially after wet rides or steam cleaning, in order to conserve your shiny chrome.
