Hot Bodies Cyclone Diff Cushion Inserts CY-08A (4 pcs) by 3Racing  [CY-08A]

Cyclone diff cushion insert kit

This CY-08A kit from 3Racing contains four cushion inserts designed for Hot Bodies Cyclone Sport and Racing differential assemblies. The inserts serve as internal shock absorbers to reduce the transmission of impact forces through the diff during hard landings and load changes.

The kit includes 4 pcs supplied as direct replacements. Fit them while rebuilding a diff or during regular servicing to restore damping where old cushions have degraded and created lash or unwanted noise. They are offered as an aftermarket maintenance part for hobbyists tuning their models.

Installation is straight forward for those familiar with differential work: open the diff case, remove any existing cushions, locate the new inserts in the correct positions, and reassemble while confirming smooth gear engagement. Only common hand tools are required, and careful attention to bearing and gear alignment is recommended.

Cushion stiffness affects how impacts feed into the gear train; changing to different inserts can modify acceleration and cornering feel. Verify fitment with Hot Bodies Cyclone Sport or Racing diff cases for the intended performance outcome.
