1976 Honda CB550F · Stem nuts & bridge washers Buying guide

Order each washer for the correct steering location

The stem washer belongs with the steering stem nut; the bridge washers serve the fork-clamp positions. Compare the original references and mounting locations before selecting hardware or a different nut finish.

Compare the washer reference and service position

The stem washer replaces 90503-283-000 and is sold each. The bridge kit supplies two washers, reference 53235-300-000, for the fork-clamp locations. Inspect those separate positions when the top bridge is apart; a similar finish or general “triple tree” description does not make the washers interchangeable.

Choose the nut finish after checking the threads

The chrome nut and Joker Machine black alternative both list reference 90304-415-000 and a 30 mm hex. The black product is CNC-machined and made in the USA. Choose the finish after confirming the installed application, and use the Honda procedure for assembly and tightening; new hardware cannot repair damaged mating threads.

Steering Stem & Bridge Hardware FAQs

Is the stem washer included with the chrome nut?

The nut and stem washer are separate, individually sold products. Inspect the washer already installed, then add reference 90503-283-000 if a replacement is needed alongside the 90304-415-000 nut.

Will the bridge washer kit replace the stem washer?

The two-piece bridge kit serves the fork-clamp positions and references 53235-300-000. The individual stem washer references 90503-283-000. Choose by the removed part and its position instead of substituting one washer product for the other.

Is the black nut listed for the same CB550F application?

Yes. The Joker Machine black nut includes CB550F 1975–77 and reference 90304-415-000, with a 30 mm hex. Compare the fitted hardware first, then choose the chrome or black finish for the restoration.
