1971 Honda CB350K3 · Shock Mounting Parts Buying guide

Renew the upper mounts with the correct quantities

Honda lists two upper joint rubbers and two 90309-315-000 nuts for the K3. The rubbers come as a set of two; the nut order needs the quantity required for the job.

Parts to consider

Use the K3 upper-mount references

The K3 upper nuts reference 90309-315-000, and the joint rubbers reference 52484-292-000. The featured rubber set contains two, matching the original bike’s two upper joint positions. Inspect the adjoining washers and mounts rather than treating these items as a complete shock installation kit.

Choose complete dampers by fit, not finish

A chrome or black finish does not answer the mounting questions. Check mounting-center length, upper-eye bush dimensions and lower attachment, then verify clearance through suspension movement. The catalog includes custom lengths and differing end styles, so obtain confirmed K3 fit before ordering complete replacement shocks.

Buying questions

How many upper joint rubbers do I need?

The original K3 uses two upper joint rubbers, and the featured product supplies a set of two. Confirm that the installed shocks retain the corresponding upper joint arrangement before ordering.

Are two upper nuts required on the original K3?

Yes. Honda lists two 90309-315-000 upper nuts for the K3, one for each shock position. Select the number you need and inspect the associated mounting hardware separately.

Can I choose a shorter shock just because its upper bush fits?

No. Length, lower attachment and available clearance all matter. A matching upper bush establishes only one dimension. Have the complete installation checked before choosing custom-length shocks for a changed ride height.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
