1972 Honda CB350K4 Rear Shock Mounts

Before replacing K4 rear shocks, separate worn mounting parts from the dampers themselves. The upper joint rubbers and retaining nuts have verified K4 references. Complete shock choices also require a check of length and lower-mount arrangement on the motorcycle.

1972 Honda CB350K4 · Rear Shock Mounts Buying guide

Renew the mounts with the correct quantities

The K4 uses two upper joint rubbers and two shock absorber nuts. The rubber product supplies a pair, while the nut order must reflect the number being replaced.

Parts to consider

Honda CB Shock Absorber Joint Rubber Set/2 ~ Replaces 52484-292-000 Upper shock joint rubbersSet of two rubbers replacing 52484-292-000; the K4 uses two at its upper shock joints.View part Honda CB OEM Type Shock Absorber Nut ~ Replaces 90309-315-000 Shock absorber nutOEM-type replacement for 90309-315-000. Two nuts are used on the K4; order the quantity required.View part

Upper rubbers and nuts are separate

The two-piece rubber set replaces 52484-292-000, matching the K4 upper shock-joint requirement. The OEM-type nut replaces 90309-315-000 and is ordered by required quantity. Inspect the fitted mounting parts rather than assuming complete shocks include the hardware you need.

Compare complete shocks carefully

The available catalog includes 290mm custom shocks and longer alternatives, with differing mounts and adjustment features. The K4 rear shock assembly was revised. Measure the fitted assembly and confirm an appropriate replacement before treating a multi-model stock-length description as a factory K4 specification.

Buying questions

Do I need two packs of upper shock rubbers?

One pack contains two rubbers, matching the K4’s two upper joint rubbers. Order based on the mounting parts being renewed, and inspect any altered shock arrangement separately.

How many shock nuts does the motorcycle use?

The K4 uses two nuts corresponding to 90309-315-000. The replacement is an OEM-type nut; order the number you need rather than assuming one line item supplies both.

Are the 290mm custom shocks direct stock replacements?

Treat them as custom choices requiring a full mounting and clearance assessment. Some use eye-to-clevis mounts and another uses eye-to-eye mounts, so the same length alone does not establish compatibility.

Not sure which part you need?

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