The Adjustable EP3 Pulley kit is the newest addition to our ever growing parts line-up. Up until now, people that chose to use the oem Honda EP3 Idler pulley have encountered problems with over-tightened or loose accessory belts. This is because the original factory EP3 idler is fixed and not adjustable.
Our EP3 Pulley kit allows the user to correct the length of the accessory belt by manual adjustment, to keep tension in the perfect service window.
K24 / K20 engine combos will appreciate the adjustability of this part even more because of the parts mixing that occurs on these setups.
For some swaps, like a K24 engine swap into a 06-09 Civic, people have even started using the smaller K20 crank pulleys in an attempt to correct the accessory belt length.
Unlike our very popular A/C & P/S Eliminator Pulley Kit that relocates the alternator, the EP3 pulley kit also allows the user to keep A/C installed if desired.
However, as a default the kit is sold with the correct length belt to delete A/C.
Fits ALL K20 Engines / ALL K20 Heads
