Peugeot 309 GTI-16 Billet Alloy Bottom Pulley - Underdrive - Silver
Peugeot 309 GTI-16 XU9J4 Billet Alloy Underdrive Bottom Engine Pulley
Designed specifically for high revving applications.
Maintains the optimum alternator speed when crank exceeds the factory limit. Suitable for up to 9,500rpm.
The Spoox Racing Developments billet pulley will increase the engines responsiveness to throttle inputs and will allow the engine to rev more freely, our lightweight pulley reduces the engine’s parasitic losses – namely, the amount of power that is absorbed accelerating the internal mass of the motor. They are also the only pulleys on the market to be statically and dynamically balanced to prevent engine wear from excessive vibration.
The Spoox Racing Developments bottom pulley has been precision CNC machined from one piece HE30 aluminium billet, they are then hard anodised to prevent corrosion & premature wear and also have the timing hole present.
The Spoox Racing Developments alloy bottom pulleys are designed as direct replacements for the Peugeot cast iron versions, but they weigh less than half the weight of a standard pulley - just 178 grams.
The billet pulleys are available from stock for immediate despatch and are supplied with four probolt titanium retaining bolts & washers.
Ideal for use on Peugeot 205 & Peugeot 309 Mi16 conversions.
