1970 Honda CB450K Rear Shocks & Joint Hardware

The 321mm and 335mm families list different dimensions, and the 290mm shorty sets are for custom applications.

1970 Honda CB450K · Shock Absorbers Buying guide

Measure the shocks before deciding which set to purchase

The chrome 321mm set has five preload positions; the 335mm sets have four and list mounting hardware plus a wrench. The 290mm options require custom fit checks, including whether the lower end is a clevis or eye.

Compare each shock family without inferring factory geometry

The 321mm product is described as stock-design, and the 335mm products as stock-length. Use their actual measurements and references to assess the fitted motorcycle. These names do not verify one original CB450K dimension, unchanged ride height or clearance for a set of a different length.

Resolve the custom mounting details before purchase

The eye-to-clevis shorty listings specify their upper bushing but omit lower clevis width and lower bolt diameter. The separate eye-to-eye version gives 10mm ID × 21mm bushings at both ends. Confirm the complete intended mounts and clearances before ordering any 290mm custom set.

CB450K buying questions

Can I choose the 290mm set as an ordinary stock replacement?

These sets are expressly described as shorter-than-stock products for custom applications. Confirm the intended length, both mounting ends and required clearance. A CB450K application does not remove the custom fit checks or establish an unchanged suspension arrangement.

Do similar black shorty finishes mean the mounting ends are the same?

No. The eye-to-eye black shrouded version uses 10mm ID × 21mm bushings at both ends. The eye-to-clevis shorty versions instead specify a 12mm ID × 21mm upper bushing. Compare the exact product’s mounting style before choosing.

Does the joint rubber set establish the separate washer quantity supplied?

The joint rubbers explicitly come as two pieces. The OEM-type washer states two required per motorcycle but does not clearly give supplied package quantity. Check that detail separately and compare the washers already included with a chosen 335mm set.
