HYBRID RACING K SERIES IDLER BRACKET & PULLEY KIT K20 K24

Strength & Flexibility

We tackle one of the most common K-Swap issues with a new look and fresh idea. Our idler bracket and pulley kit was designed to take the guesswork out of a reliable belt tensioner system.

It's simple. Keep the OEM belt tensioner and alternator in place. Our bracket replaces the power steering pump and our guide helps you find the right belt that puts it in the OEM system in the proper tension window. No more worries about your alternator falling, belt walking, or charging issues. We also altered the geometry.

We created two kits for the modern K-Swap. One for pretty much all engines sold in the USA, Japan, and Europe and another kit specifically for the common JDM K24A engine.

HYB-IDB-01-02

This kit will be the most common setup used. Since it fits nearly all of the known K-Series water pump housings and engines it will likely be the most popular. Known to fit the K20A, A2, A3, Z1, Z3, Z4 & K24A1, A2, A4, A8 means you will just need to measure your crank pulley to have a bolt-on solution. This kit requires no modifications to your water pump housing or any other accessory part.

Improved hood clearance saving over 1.5" compared to a stock power steering pulley. It's also .5" shorter than the OEM EP3 idler bracket and pulley.

How to choose the correct belt:

This kit does not include a belt. You will need to follow these steps to determine which belt to use on your specific engine.

Determine what engine you are using. (K20 or K24)
Determine if you are using AC or not.
Measure the outside diameter of the crank pulley.
Refer to the belt sizing chart to pick the correct size based on which kit you have and the diameter of the crank pulley.

*If your crank pulley is not listed, we do not offer a belt size. The process to find a belt is the same, you'll just need to source it on your own.

PS & AC Delete Belt Sizes

These belts are sized specifically for the Hybrid Racing Idler Bracket & Pulley Kit. We offer four sizes that fit nearly all K-Series engines without AC.
