Stage X Lightweight Ancillary Pulley Kit with Air Con V8+

These Stage X lightweight auxiliary engine pulleys for the V8+ Subaru Impreza are made from high-quality aluminium, machined with the CNC techniques used by leading Formula 1 teams, then anodised to military specification.

The set weighs just 1.18 kg, 1.95 kg less than the OEM units. This weight reduction lowers the engine's rotating mass, improving acceleration and engine response.

The kit keeps the standard pulley diameters, so the existing auxiliary drive belt can be used and the power steering and alternator speeds remain standard.

Kit contents: crank pulley, alternator pulley and power steering pulley.
