Stage X Super Lightweight Ancillary Pulley Kit with No Air Con V8+

This super light pulley set is designed specifically for V8+ Subaru Imprezas. The extra weight reduction comes from additional precision machining and removal of the air conditioning drive on the crankshaft pulley.

The pulleys are made from high-quality aluminium using CNC machining and anodised after machining to a military specification.

The set weighs just 850g, 2.33kg less than the OEM units. This lowers the engine's reciprocating mass, improving acceleration and engine response.

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

The kit comprises:

• Crank pulley
• Alternator pulley
• Power steering pulley
• Replacement nut and spring washer

Air conditioning cannot be run with this pulley arrangement.
