Koswork Hardened Suspension Shafts 3x31mm (2) KOS04502-1

The Koswork Yokomo YZ870C-YZ10 Hardened Suspension Shaft 3x31mm (2), part KOS04502-1, is a pair of hardened suspension shafts measuring 3x31mm. The shafts use a threaded steel hinge-pin design and are supplied with black aluminium locknuts. Their polished finish is intended to support smooth operation, while the threaded arrangement removes the need for separate E-clips.

For suggested compatibility, Koswork lists these shafts as a direct replacement and upgrade for the YZ-009O Yokomo outer suspension arm pins used with the YZ-870C. They are made in Taiwan and provide a threaded pin and locknut alternative for the suspension arm assembly. Cars, parts and accessories shown separately are not included.
