Serpent 903666 Rear Solid Axle S988 Chassis Upgrade  [SER903666]

Serpent 903666 rear solid axle for reliable rear stability

The Serpent 903666 rear solid axle is made to suit the S988 chassis and improve stability under race loads. It is a pragmatic upgrade for drivers wanting consistent rear behaviour and straightforward durability.

Designed to Last in Racing Use

Built with endurance in mind, the axle reduces component wear and cuts down on frequent part swaps. That robustness keeps your car competitive across multiple events without extra downtime.

Smoother Power Delivery Under Load

Matched to the S988, the Serpent 903666 minimises differential slip so both rear wheels receive steady torque, which helps with traction and cleaner exits from corners.
