2 pulley Subaru WRX kit, includes crank and alternator pulleys, and belts. This kit is for the MY01-02 WRX (MY02-03 in the U.S. – the “bugeye” model), and does not include the power steering pulley, as on these models it cannot be removed. This set can also be used for all Subaru EJ20, EJ22 and EJ25 turbo and non-turbo engines.

These 3-pulley Subaru kits, include replacement crank, alternator and power steering pulleys, and the required belts. These sets are under-driven, which reduces the parasitic losses from the driven accessories, resulting in more power. Their light weight aids engine response, giving better acceleration and a more free-revving feel.

Without trying to sound clichéd, the GFB SR20DET lightweight underdrive crank pulley is new and improved! Of course, it can't be both new AND improved, so we'll go with improved!

It has been re-designed to further reduce weight, and more importantly, a steel wear sleeve has been fitted to the oil seal running surface (shown below) to greatly increase pulley longevity and eliminate potential oil leaks caused by wear over time.

Suits SR20DE and SR20DET engine in rear-wheel drive configuration only.

Honda crank pulley, suits B16A engine.

Subaru crank pulley, non under-drive style. Once installed it is indistinguishable from the stock item, but is made from 6061 alloy and weighs a mere 550g, instead of the hefty 2180g of the factory WRX unit (2575g for the STi model). Fits ALL Subaru EJ type engines.

New from GFB is the Under-drive Crank Pulley for the Mitsubishi EVO IV through to IX. Like all GFB pulleys, the material used is 6000 series aluminium alloy billet, which nets a large weight saving of 1.4 kg over the factory pulley, without sacrificing strength or reliability.

The kit comes complete with the required serpentine belt, and installation is dead easy – no specialized tools are required and it can be done in as little as 30 minutes.

The accessories are under-driven by 20%, which does NOT compromise their performance at low RPM, but does help reduce parasitic losses at high RPM.

Like all GFB lightweight under-drive pulleys, the improvement to the car is felt in the form of sharper throttle response (particularly off boost), and the engine feels more willing to rev. A useful comparison is the difference between performance on a cool evening vs. a warm day, or having the A/C off vs. on.

This is a replacement alternator pulley to suit early 12A and 13B rotaries through to series 5 RX-7 (vehicles with 15 mm alternator shaft). It allows a second v-belt to be added for improved reliability, particularly on high-revving engines.

Two alternator belts of the same size as the original are required. Note - does not change the drive ratio of the alternator.
