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

Competition-oriented cushion kit

The CY-08A cushion set from 3Racing is engineered for Hot Bodies Cyclone Sport and Racing differential units, offering four inserts designed to refine shock absorption inside the diff. These inserts moderate transient loads that reach the internal gears, helping to stabilise behaviour under aggressive driving and quick load shifts.

Each kit contains 4 pcs as direct replacements for worn or removed cushions. They are intended for service-level rebuilds and race-prep maintenance where controlled damping can be used as a tuning parameter. Install as part of routine maintenance to restore consistent damping characteristics.

Fitting follows standard diff service procedures: open the diff housing, remove old cushions, position the new inserts precisely, and reassemble while ensuring proper bearing and gear alignment. The inserts require no special tooling and are suitable for teams and experienced hobbyists focusing on predictable drivetrain response.

Tuning note: cushion compliance affects how impacts transmit to the differential gearset and can be used to fine tune traction transitions and corner exits. Confirm fit with Hot Bodies Cyclone Sport or Racing diff cases before committing to a race setup.
