The dual pulley design of the K-Tuned pulley kit provides perfect belt alignment and stability unlike some competitor’s knock-off designs. We also use billet construction on all parts. In our continued effort to perfect our pulley kit we are now including our lightweight billet alternator pulley with all kits. The alternator pulley converts the alternator from the oem 7 rib to a 6 rib design and completely eliminates belt movement. The result is a belt that is now routed 100% in line with the outside edge of the factory crank pulley. The belt itself is a high-quality Dayco poly-rib belt that ensures quiet, non-slip operation. With a K-Tuned pulley kit you no longer need to buy the EP3 idler pulley setup from Honda to complete a K-series engine swap.
The K-Tuned pulley kit eliminates both P/S and A/C from the engine as well as the factory belt tensioner. The alternator is relocated lower on the engine, giving lots of clearance on even the tightest K swap chassis. This part is particularly useful for EF K-swaps because it offers much needed headlight clearance. You can even cut off the oem mounting tab used for the original tensioner if you want. Doing this, allows ITB’s and most of the high-end custom intake manifolds to be fitted very easily. A true must have K-swap part.
This kit eliminates both A/C and P/S. There is no way to keep them with this pulley kit.

- NTN bearing (identical to oem Honda bearing)
- Belt tension is fully adjustable
- Includes a standard Dayco belt
- Allows proper clearance for the EF chassis
- Includes all hardware
Please select crank pulley type being used on your K-series engine. Note that a K24Ax crank pulley is larger diameter than a K20Ax pulley.
2017 Update: Kit has been updated with two steel brackets now (replacing previous billet bracket) and additional mounting hardware.
2016 Update: Kit has been slightly revised. Now includes a nut w/threaded knob to help with manual tensioning. Once tension has been set the top bolt dose not need to be used and can be removed. You can also cut the bottom of the bolt if you want to lower it as well.
2016 Note: light modifications may be required for proper fitment - K24 alternator 'lip' may have to be grinded down a bit in order for proper alignment of pulley kit.
