1978 Honda CB550K · Shock Absorbers Buying guide

Use mounting dimensions to narrow the shock choices

Length, eye width and lower mount pattern matter before colour or shrouds. Compare the set’s measurement method and contents with the retained mounting arrangement, then assess loose nuts, washers and joint rubbers separately.

Parts to consider

Resolve the two stock-style length descriptions

The 321 mm set is called stock-design, while several 335 mm sets are called stock-length. Those descriptions do not establish the same original length on this motorcycle. Use the actual measurements and mount details to choose, and confirm any mounting washers needed without guessing a shim quantity.

Distinguish short custom mounts from stock-pattern choices

The black-shrouded 290 mm option uses eye-to-clevis measurement and has its own upper-bushing specification. Another short option uses eye-to-eye mounts, so matching a length number alone is insufficient. Keep the custom suspension plan separate from selecting loose replacement nuts, washers and joint rubbers.

Common questions

What comes with the 335 mm chrome set?

Its description lists bushings, inserts, washers and a preload wrench with the shocks. Compare that package with the retained mounting pieces; the loose shock nut and washer products have their own references and purchase descriptions.

Do all 290 mm options have the same mounts?

No. The selected black-shrouded set is measured eye-to-clevis, while another short option is explicitly eye-to-eye. Compare the upper and lower mount styles and stated bushing dimensions before selecting a custom set.

Does two washers used mean a two-washer package?

The loose washer listing states two are used on the motorcycle without identifying a two-piece purchase package. Confirm the quantity supplied and inspect the retained usable washers before deciding how many to order.
