Stage X Lightweight Ancillary Pulley Kit with Air Con 1992 - 2000

These Stage X lightweight auxiliary engine pulleys for Subaru Imprezas built from 1992 to 2000 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, power steering pulley, and a replacement nut and spring washer.
