2002-2006 Acura RSX, 2002-2005 Honda Civic Si, and 2004-2008 Acura TSX K-Series Idler Bracket & Pulley Kit by Hybrid Racing

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 too.

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 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 0.5" shorter than the OEM EP3 idler bracket and pulley.

HYB-IDB-01-04: This kit was specifically designed to fit the JDM K24A engine. This engine was never offered in the USA, however, has become very popular with engine importers. The HYB-IDB-01-04 includes a specific spacer bracket designed to be used on this engine only. From our research, there is no other engine like this in the US, therefore no other OEM option that we have tested worked.

Our kit improves hood clearance by being 1.81" shorter than the factory K24A power steering pump.
