1978 Honda CB400TII Hawk II · Swingarm Service Parts Buying guide

Identify the pivot cover or shock mount first

The genuine Honda dust cap protects the swingarm pivot area. The rubber-and-metal bushing belongs at the lower shock mounting point on the swingarm. Both products are sold individually, so count the positions being serviced.

Separate the two rear suspension locations

The original swingarm uses four pivot dust caps and two lower shock mounting bushings. A split cap and a loose shock attachment therefore need different parts and order quantities. Identify the position first, then inspect the mating hardware before deciding how much of the assembly to renew.

Check altered rear suspension carefully

Replacement swingarms or shocks can change mounting requirements. Compare the lower bushing dimensions with the installed joint and inspect the pivot arrangement before choosing dust caps. Follow the Honda manual for supporting the motorcycle and servicing the assembly; do not work from product dimensions alone.

Common buying questions

Is the swingarm dust cap genuine Honda?

Yes. The featured cap is genuine Honda 52144-356-005 and is sold individually. It protects the pivot area; inspect the number of cap positions being serviced before choosing your quantity.

Where does the rubber-and-metal bushing go?

It belongs at the lower rear-shock mounting point on the swingarm, using reference 40548-268-000. Its dimensions are 19 mm long, 22 mm outside diameter and 10 mm inside diameter.

Does ordering one supply both sides?

Each item is sold individually. The original 1978 Hawk II uses four pivot dust caps and two lower shock bushings. Order to the positions being serviced, checking any changed suspension separately.

Not sure which part you need?

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