Motorcycle Shock Absorber Body Parts

The rear coilover on your motorbike has a cast aluminium main body that ties all the other suspension assemblies together - available in bare alloy or anodized with a performance Kashima coating.

At the top, shock bodies bolt to the bike's chassis via mounting bearings and grease seals to keep the travel smooth. The outer case has a cylinder inside for the damping piston to slide in, sometimes with an extra tube piggybacking on the casting for holding a gas bladder and giving a larger oil volume that is great for cooling. At the bottom end surrounding the shaft is a stopper cap that acts as an armoured plate protecting the delicate Seal Case Assembly from stone strikes and corrosive mud. Rebuildable non-piggyback shocks often have a service port or bolt drilled into the body so you can drain the old oil and regas the damper after servicing. Threaded onto the outside of the shock casing are large preload nuts that the coil spring collar seats against - they are adjustable to allow the bike to change for different rider and luggage weights.

We sell naked cases, as well as all the individual components attached - bleed screws, o-rings, collars, retaining c-clips, etc.
